Help Compiling Launcher.apk from Cyanogen Source Code

The title says it all, here is what I have done so far:
1. Installed Eclipse 3.5, ADT 0.95, SDK1.6r4 (all platform updates and tools), Java JDK 1.5, all additional suggest downloads from AOSP.
2. Set up repo via:
Code:
curl http://android.git.kernel.org/repo >~/bin/repo
chmod a+x ~/bin/repo
repo init -u git://android.git.kernel.org/platform/manifest.git
repo sync
wait..................
3. I then moved the HTC recovery image to ~/mydroid and copied the proprietary bits via
Code:
cd /vendor/htc/dream-open
./unzip-files.sh
4. I then entered
Code:
source build/envsetup.sh
lunch
and on different attempts have tried 5. aosp_dream_us-userdebug, and 7. aosp_dream_us-eng.
5. Finally, I entered (from ~/mydroid)
Code:
make Launcher
mmm packages/apps/Launcher
From here everything compiles, and a Launcher.apk appears in ~/mydroid/out/target/product/dream-open/system/app
When I push this to /system/app in my G1, I have a blank screen, so obviously the Launcher is not compiled correctly. My goal is to have a 3 screen browser (which is the default in launcher.java) so I have changed nothing in the source files. I am quite a noob when it comes to compiling source code, so I am at a loss here. Any help would be greatly appreciated.

Anyone, I know this is not hard for a real dev, but how many actually look in Q&A? I am starting to see why people post questions elsewhere.

[Dev] Modify stock image script

In case someone would like to build an own image based on the stock firmware,
I wrote a script that performs the neccessary steps (which where mostly described at the xda-forums) automatically on a linux based system.
It is very raw, and is not well optimized. It also is using many sudo calls for creating and modifying the image. Maybe someone has another, better solution.
Usage:
Download and unpack the ExtractAOS archive:
Code:
tar xfj ExtractAOS.tar.bz2
At first you need to place a AOS update file (firmware_archos_it4.aos) into the "dl" folder.
Then copy a busybox.tar.bz2 file, which contains the statically linked binaries of busybox (no subdirectories) inside the archive:
Code:
ash
busybox
cat
chgrp
...
Also make sure that following tools are installed on your system:
unsquash
unzip
tar
Then start the main script:
Code:
./unpackAOS
You will see a menu like this:
Code:
---------- Unpack and Modify Archos image -----------
1 Cleanup: Umount all mounted devices and delete all created files.
2 Download needed packages
3 Setup build directory
4 Create new Ext4 loop image and mount it to MOUNT_DIR
5 Extract AOS image
6 Copy AOS image contens into /data/ExtractAOS/archos_update_folder
7 Modify image in /data/ExtractAOS/archos_update_folder
8 Finish image and unmount it
88 Perform step 3-8 automatically
99 Exit
Then download needed tools via menu item "2".
If the download are successfully done, then you can enter "88"
to build your own archos.ext4.update image file.
Notes:
I'm on a 64 bit system. Letama seems to provide binaries also for 32 bit sytems. In that case, you can modify and set the correct binary within the script file.
This script is intended to provide a base for developers which want their own customisations
Special thanks to:

Thanks i will try it next weekend

On which firmwares did you test this script?
There was an error in squashfs header in 4.0.5-4.0.6 FW (including test releases)- androidmerged.squashfs.secure could be mounted as loop but not extracted

Hi,
I builded my image based on the current 4.0.7 aos-update file.
I'm using archlinux 64 bit.
Which arch are you using? Can you please verify that the correct extractAOS binaries are downloaded within the script?
The script doesn't mount the androidmerged.squashfs.secure as loop device, but copies all the data from androidmerged.squashfs to a temporary folder named "output_folder".
Can you please provide a console output? Maybe there is some more information?...

I didn't test the script (I stick to 3.2.80).
For modifying I use LeTamas' "manual" method- correct binaries are present (linux 32bit). Unpacking .aos file works fine but I had problems with unsquashfs (header error in =<4.0.6 fw) so the only option was mount -o loop.
If it works for 4.0.7= Archos corrected the error

Hi!
I've just downloaded the 4.0.6 version from archos servers.
Code:
h**p:// update.archos.com/9/gen9/gen9_4.0.6/firmware_archos_it4.aos
Unpacking of the squashfs still works here...
Maybe you missed the needed steps:
Code:
cd $BASEPATH/firmware_archos_it4/root/data
dd if=androidmerged.squashfs.secure of=androidmerged.squashfs bs=256 skip=1
if [ -d output_folder ]; then
rm -f output_folder
fi
unsquashfs -d output_folder androidmerged.squashfs

Maybe stupid question but why we need this busybox ( this archive actually is missing)? I think there is busybox already from the archive is that archive is rooted or give us something more?

Hi,
I saw that another customized roms contains an updated busybox, which can provide more features.
(Honestly, I don't know which feature is it worth to replace the builtin busybox... . :angel
If you want to build an image without this step, just comment out the busybox call.
The busybox archive is missing, because I don't know If I have the permission to include a compiled (from other people) busybox by default.

[Dev] CM9 Mod Extension
Help!
I can't wait to try out the final build from Anybody interested in testing a CM9 super-alpha build in a week or so?, so I decided to try out a modification of the stock rom with CM9 by myself. And yes, today zygote has startet and I got a screen =)
I would like to share with you, what I did and I hope that you can give some code extensions to build a better mod script.
So, let's go:
1) Compile cyanogen mod
Install prerequisites
(I used Ubuntu Precise 32bit in a chrooted environment)
Then perform like suggested a repo init/sync:
Code:
repo init -u git://github.com/CyanogenMod/android.git -b ics
repo sync
Then perform a compile action:
Code:
. build/envsetup.sh
lunch full_panda-eng
mka
PS: I had to modify the cyanogen_root/external/webkit/Android.mk
because there where build errors:
Code:
# Build the performance command line tool.
#include $(WEBKIT_PATH)/android/benchmark/Android.mk
Get some coffee I full build will take about an hour (on my system).
2) Unpack Archos stock image
You can use my tool at #1 of this thread!
PS: I used 407 stock image...
3) Create a loop image and mount it into a folder
You can use my script for that.
4) Get my new archive and unpack it.
Go into that folder and modify the bash script Porting.sh to match the folder paths:
Code:
export CYANOGEN=/cynogen_mod/out/target/product/panda
export STOCK=/ExtractAOS/firmware_archos_it4/root/data/output_folder/
export OUT=/Android/Development/mount
Run the script as root!
Code:
sudo ./Porting.sh
You get a file system contents in $OUT. Unmount the loop directory and
load it into the media update path as usual:
Code:
adb push archos.ext4.update /data/media/ && adb reboot
That's it! You should get a CM9 desktop.
------------ ------------ ------------ ------------ ------------ ------------ ------------ ------------ ------------
That was the good news! The bad:
The current state is a proof of concept.
I'm really hope that you can contribute to the modding script: I'm not an android expert!
Dirty technical details:
I had to use the existing vendor libraries especially the graphics drivers (I tried to use the panda binaries, with no luck :-/ ).
I moved them into the /system/vendor/lib folder and symlinked the libraries to /system/lib. This way it seems to much cleaner.
I modify the init.rc script to mount the data directory into /data2 to not interfere with existing archos installation. Later we should be able to point to that directory again. (Hint: to update the development you must use a adapted adb update command:
Code:
adb push archos.ext4.update /data2/media/ && adb reboot
From the first test, I saw that I have no real touchscreen, it worked like a "mouse" controlled environment. Maybe because the panda board has an mouse as input device.
Thanks.
PS: I'm curious how JackpotCalvin has solved the CM9 integration, It sounds way better than my solution...

Nice one
Some thoughts:
-why do you copy $STOCK/usr/bin/[binary name] when later all $STOCK/usr dir is copied?
-there should be no need to place PowerVR in /system/vendor/lib/[...], /system/lib/[...] should work fine
-check prelinks for existing libs and adjust prelink map for [repo path]/device/ (this may not be necessary, last system I compiled was Froyo)

I'm stopping my efford because I'm at a point, where I learned that just replacing the files between both sources (Panda Board CM9 builded binaries and Archos Stock ROM) is not a 100% solution.
I resolved my input devices setup, by copying the corresponding icd (and other) foles to the output folder. Then I had unresolved issues by getting WLAN to work. I found out, that in libandroid.so and libandroid_legacy.so are coded the modules which are needed for WIFI. Panda board is compiled w/o WIFI, so there are no
wifi modules loaded. (After I load wl12xx_sdio.ko manually by using insmod, the wlan was functional!).
The solution IMHO must be, to compile an adapted CM9 with all hardware specific settings. Maybe the customized files can also moved inside the device configuration directory so that the merge script is obsolete (my hope).
So I decided to either to wait until JackpotClavin is posting his CM9 configuration files
Code:
http://forum.xda-developers.com/showpost.php?p=28439197&postcount=80
or to learn how to make a new device on CM which maches our Archos device. (Maybe someone else can give me some archos specific instructions).
Update: Great! JackpoClavin has provided sources =)

[GUIDE] How to build CM10.1 (Android 4.2.1) for the Nexus 4 (mako)

This is a guide to build cyanogenmod 10.1 (Android 4.2.1) for Google Nexus 4. This guide is for linux. I will add a guide to build on mac soon, but the basic principle is the same.
Preparation
You need a fully working build environment. If you don't have one running already, you can follow the official android guide on how to set up build environment. Follow the easy steps in the guide.
Check this guide by sylentprofet about how to get the build environment set up.
Your build environment is now set? Good, let's start!
Get the sources
Start by creating a new working directory for CM10.1. You can create this anywhere on your workstation.
Code:
$ mkdir ~/cm10.1
$ cd ~/cm10.1
£ mkdir -p bin
Initialize Repo for Android CM10.1 (Android 4.2.1):
Code:
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ repo init -u git://github.com/CyanogenMod/android.git -b cm-10.1
and enter your credentials if needed.
Download the sources:
Code:
$ repo sync
Wait until it is finished. It will take a long time, depending on your internet connection.
Obtain the device build files and proprietary files:
To do this create a file named 'local_manifest.xml" in the .repo folder. This is a hidden folder, so you have to allow your visualisation of hidden files, alternatively run "open .repo" code from terminal. Or you can just run the code below to create the file directly into the folder.
Code:
$ gedit ~/cm10.1/.repo/local_manifest.xml
For Mac you can use:
Code:
$ touch ~/cm10.1/.repo/local_manifest.xml
Paste the following lines into the file:
Code:
<manifest>
<project name="TheMuppets/proprietary_vendor_lge.git" path="vendor/lge" remote="github" revision="cm-10.1"/>
<project name="CyanogenMod/android_device_lge_mako" path="device/lge/mako" remote="github" revision="cm-10.1"/>
<project name="CyanogenMod/lge-kernel-mako" path="kernel/lge/mako" remote="github" revision="jellybean"/>
</manifest>
Save the file. And rerun the code:
Code:
$ repo sync
Download the necessary pre-builts:
Code:
$ ~/cm10.1/vendor/cm/get-prebuilts
That's all the sources ready now.
Edits for mac only
If you try building now you will get elf errors when the kernel is being compiled. There are different way for fix this, but I'm using this method.
Go to /kernel/lge/mako/scripts/mod/ folder, open the file 'mk_elfconfig.c' and replace
Code:
#include <elf.h>
with
Code:
#include "elf.h"
. Do the same in the file named 'modpost.h'. Next download the attached file named 'elf.h' and copy to the same folder. You are now ready to build.
Building CyanogenMod
Run the following command:
Code:
$ . build/envsetup.sh
and build by running:
Code:
$ brunch mako

Go go the gerritt review site, click on 'cherry-pick' and the copy the code displayed underneath. On terminal direct to the required folder and then paste the code on terminal. So if the change is in 'frameworks_base', do 'cd ~/cm10.1/frameworks/base' and then paste the code.

This might help..

I finally got Cm10.1 to build correctly on my own after days and days of troubleshooting. I wish I would have seen this guide earlier! I am having one slight problem though. Every time I sync, it hangs at 99%(353/356). It always hangs up on the last 3 projects. Everything builds fine. I think it has something to do with prop files. I've tried pulling them from the phone and using "The Muppets" github in local_manifest.xml, but it makes no difference. It hangs every time. I've let it sit for hours and nothing. It was syncing all the way through just fine, but a couple days ago it stopped and hasn't synced properly since. If anyone has any ideas I'd greatly appreciate it! Thanks.

how do i move the file when it is done compiling? it says" The file "cm-10.1-20121222-UNOFFICIAL-mako.zip" cannot be handled because you do not have permissions to read it."

Anyone having luck building in Ubuntu 12.04, Just curious as I am on 10.4 (x64) as advised by Google but that update button is begging me to press it. Also will upgrading from 10.4 to 12.04 destroy my Android/CM build enviroments or will everything remain in tact??

It should work on 12.04, as the cyanogenmod official guides are written for that version of ubuntu. I can't say whether the build environment will remain the same or not.

There are different packages to set up the build environment in 12.04 that are listed on googles site. They work. You can upgrade, but you would have to install the new packages. They also work on 12.10 fyi.
I was wondering if anyone has successfully set up the build environment in Mint 14? The packages for 12.04 won't install. If anyone can help, I would be grateful.

[GUIDE]Development for GalaxyTab 7.7 and Plus. How hard could it be?

Planning this for sometimes. So much work ahead. Just studying the new code cause me a lot of time. I think I have to rush it out so that someone may share my burden. Don't have much time to polish it. I'm trying to provide all commands, files and links. Please correct me if something is wrong or missing. Hoping this could be a stepping stone for those interested. If you like challenge, it'll be fun!
1. Introduction
If you have watched "Top Gear", you would have heard Jeremy Clarkson said "How hard could it be?". Why is it so hard to build a rom for our tab?
When I first play with rom building, it was quite straightforward. I recuilt my retired PC (Celeron 1.2G with 3G RAM, 40G HD) and follow the guild for building PA. Installing Ubuntu 12.04 and then the necessary packages. Everything is ready in a few hours. It was really challenging your patience to repo sync the source. After a few retries, I finally completed the download in two days! After two hours, my harddisk is full! Then I collected another retired 80G HD from a friend. Re-install everything and build again. Building requried 7 hours on my antique PC. With only a few minor errors to correct, my first rom pa2.55 was out. So how hard could it be? It was our predecessors ( @ohanar, @locerra, etc.) :good: who had already done lots of hardwork on device trees and kernel! If Samsung has really released the hardware related sources, there will not be so much troubles for us. At the time Android 4.2 launch, we have a new problem. Our tab's CSR chip doesn't support Bluedroid. See the Nexus family, everything is ready. Rom building will never be so pain in the ass as us.
1.1 What's wrong with our hardware
GT-7.7 and Plus use the exynos4 smdk4210 board with Mali-400 GPU. Quite a number of devices have similar hardware. The main problem we have would be:
1.1.1 CSR bluetooth chip.
CSR chip doesn't support bluedroid which become standard after Android 4.2. Bluez.org has provide a solution for 4.2 early this year but porting to 4.3 and 4.4 may take some time.Working on it now. Anyone has experience on bluetooth are welcome to help.. Bluez working now. See my Thread How to port Bluez to Android 4.4. Cheers!:highfive:
1.1.2 Athero wifi chip.
Samusng's wifi driver has issues on 5G support and SOD. I'm using the modified kernel driver from Samsung's 4.1.2 source. Athero provide drivers for 3.1 to 3.10 linux kernels but they have no wakelock support. I also wrote a drive base on Athero's source and add wakelock support but have no time to polish it now. Athero's chip doesn't have firmware for AP as Boardcom. Which is also the way Android platform providing wifi tethering in framework. To support wifi tethering we have to change the framework and the driver. Anyone has experience in linux HostAP are welcome to help. Wifi tethering is ok now! Tutorial will be in Post#2 soon.
1.1.3 modem chip (xm6260).
RIL stand for (radio interface library). Most of the phone manufacturer would provide their own vendor lib. The only working blob now is Samsung's ICS propietry libsec-ril.so which is obselete now. The one from stock 4.1.2 not working but no time to trace. It also don't seems to have much difference. This library handle the AT commands issuing to the (baseband to) modem chip. xm6260 has a complete set of command manual. It should not be too hard to rewrite if we can hack the ports. However it is not worth to splend too much time on this. Those has experience in AT commands are welcome to help.
RIL details: http://www.kandroid.org/online-pdk/guide/telephony.html
1.2 Where to get the source?
1.2.1 Samsung's source for our tab
The best source would be from Samsung http://opensource.samsung.com/. Sadly, the source from Samsung only cover the kernel. Our tab only have source up to 4.1.2 and kernel source 3.0.31 from Samsung.
1.2.2 Samsung's source for other devices
Luckly, we have similar architecture to some newer Samsung models. Their source is our major source now. eg. We can use the Mali driver from Note8 and/or i9300.
1.2.3 Manufacturere's web site.
The other source would be from the chip manufacturer. eg. Athero has source for linux.
1.3 What is going on at boot?
1.3.1 Power ON
a) When power button is long pressed (should be released after the logo shows otherwise it will reboot again every 6 seconds). The manufacturer's bootloader would show the vendor's logo. At that moment, bootloader would sense if there are key being pressed. Standard Android will go to boot menu when pwr + vol- is pressed. Samsung would go to download mode (something like fastboot) and accept pwr + vol+ to start recovery mode. If no other key is pressed, it would be a normal boot.
b) When USB is plug in (PC usb port or charger) at power off, the tab will be turn on silently. It is in the LPM (low power mode). According to lpm.rc (executed by Init, will be explained in 1.3.3), CPU will be set to POWERSAVING and the program charger is running. It should only handle simple tasks like Detecting the pwr button to show the charging images. If the pwr is long press when showing the charging image, it will reboot as in a).
3) Lollipop LPM: charger is link to the program /sbin/healthd. The process is similar to b) but lpm.rc is merged to init.rc.
1.3.2 Boot image
For our tab, there are two parts for a boot.img or a recovery.img. kernel binary and initramfs. As the name imply, Init-Ram-FS is the initial file system loaded into ram when the devices boot. Kernel binary provide the hardware drivers libraies which communicate with the hardware and baseband. At normal boot or recovery mode, the image (in /boot or /recovery partition) will be decompressed and loaded to memory. Initramfs will be loaded in root(/). It would consume a few hundreds MB of RAM and that's why our free ram is only 7xxM.
In LPM, it would depends on the last boot state. If it was powered off from recovery, recovery.img will be loaded and handle the LPM. If it was powered off from platform, boot.img will be loaded and handle LPM. That's why It might show different charging images if the charging images for reovery.img and boot.img are different.
Stock cook roms can unpack and modified the initramfs from the existing zImage. It is created in system/core if we build it from source. Here is a tool which can unpack/repack our boot.img or recovery.img.
1.3.3 Init
There is the Init program in every initramfs. This is the first program to run according to the sequence in the init.rc (or lpm.rc when in LPM). Partitions will be mounted and symlinked, default values and permissions are assigned, services will be started, etc. The source of Init is in system/core. The last thing Init do would be the continuous eventloop to process events.
2. Getting Start
To start building, we need the building environment. Many tutorials have alreay covered the details so I just list my suggestions. The guide from Google is a bit outdated but really helpful. http://source.android.com/source/building.html
Basic knowledge of linux is required. All commands are run in a terminal.
2.1 Hardware
A decent PC with as much ram as possible. Thanks for the donations, I can upgrade to a better i5 notebook with 4G ram and a 500G partition only for building. It would take 3+hrs. for a clean build. RAM and Harddisk speed are essential. A desktop PC with same configuration will be faster since notebook harddisk is slower. I plan to add more RAM when the price drop (seems to be a long wait )
RAM: 4G or above is recommended.
Harddisk space: 30G+ for system, 60G+ per rom, size of ccache (50G-100G), Roughly, a partition with at least 120G for one rom. Bigger is better.
A decent internet connection is essential. It will take days to sync the source if you only have bandwidth of 2M or less .
2.2 OS
64bit Ubuntu Desktop 12.04 or above. Recommend 13.04 or above. I'm using the latest 14.04.
2.3 Install the required packages
These packages are required during building and packing. (eg. gzip is required to compress the kernel binary)
type command: (have a beer or coffee. It will take a while)
Code:
[I][COLOR="Green"]For Ubuntu 12.x and 13.x:[/COLOR][/I]
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 \

2.4 Insatll android-sdk
Download (for Linux 64-bit of course): http://developer.android.com/sdk/index.html
Extract the file to a directory (eg. ~/android-sdk)
Add the path to ~/.bashrc
type command:
Code:
sudo gedit ~/.bashrc
at the bottom add the path
Code:
export PATH=~/bin:~/android-sdk/tools:~/android-sdk/platform-tools:$PATH
Quit and restart terminal to commit the changes.
Verify the path and update the SDK
type command:
Code:
android
2.5 Install java
If you have installed eclipse, openJAVA is ready. Some say it is not suitable for android development.
I've tried both and I found no appearing difference.
To install SUN JAVA (Ubuntu 13.04 or above)
type command:
Code:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java6-installer
For Lollipop: openjdk 7 is required
Code:
sudo apt-get install openjdk-7-jdk
2.6 Install repo
type command:
Code:
mkdir -p ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
2.7 Add usb dev rules
Which are required for adb and fastboot, eg. View attachment 51-android.zip
type command:
Code:
sudo cp 51-android.rules /etc/udev/rules.d
sudo chmod 0644 /etc/udev/rules.d/51-android.rules
2.8 Enable ccache
type command:
Code:
sudo gedit ~/.bashrc
add lines for CCACHE
Code:
export USE_CCACHE=1
export CCACHE_DIR=~/android/.ccache
Quit and launch the terminal again to commit the changes
ccache will cache the object files of gcc for next build, it would increase the speed of subsequent builds alot.
After source is sync in 2.11 and before build, we can set the size of ccache first.
type command:
Code:
~/android/rom/prebuilts/misc/linux-x86/ccache -M<size>
2.9 Init the source
Make a new working driectory for your rom
type command: (eg. ~/android/rom)
Code:
mkdir -p ~/android/rom
Each rom has its own manifest.xml listing all the required projects.
It is usually in the project android (manifest for PA). The readme of this project would provide the command to init.
eg. CM11.0: https://github.com/CyanogenMod/android/tree/cm-11.0
type command:
Code:
repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0
It will fetch the manifest.xml and put it into a hidden directory .repo in the current directory (~/android/rom/.repo)
2.10 preparing local_manifest.xml
It is not a good pratice to change the manifest.xml directly. If the ROM has change its manifest, you would require to init again. The right way is putting everything your device needed in a seperate file .repo/local_manifests/local_manifest.xml. The device trees and kernel source for GalaxyTab 7.7 and Plus : https://github.com/danielhk?tab=repositories
eg. cm11.0 for p6800
Code:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="danielhk/android_hardware_atheros_wlan" path="hardware/atheros/wlan" />
<project name="danielhk/android_device_samsung_p6800" path="device/samsung/p6800" />
<project name="danielhk/android_device_samsung_smdk4210-tab" path="device/samsung/smdk4210-tab" />
<project name="danielhk/android_kernel_samsung_smdk4210" path="kernel/samsung/smdk4210" />
<project name="danielhk/proprietary_vendor_samsung_smdk4210" path="vendor/samsung" />
<project name="CyanogenMod/android_hardware_samsung" path="hardware/samsung" />
</manifest>
Note: Settings will follow manifest.xml. cm-11.0's manifest has default remote="github" and revision="refs/heads/cm-11.0" so we can omit the same entries here. For other roms, see the defined names in manifest.xml and change accordingly. You can also add other devices trees here if you want to build them for the same rom.
2.11 sync and build
To fetch the source (specified in manifest.xml and local_manifest.xml) to working directory (~/android/rom)
type command:
Code:
repo sync -j32
-J specify the no. of threads to download. I have a few trials. Seems 32 works for me.
When it is done. You will find that ~/android/rom is not empty now.
You may set the ccache size now:
type command: (eg. 50G)
Code:
~/android/rom/prebuilts/misc/linux-x86/ccache -M50G
Only if you want to change size, otherwise it only requires once.
To build a rom, change to the rom directory. Usual commands: (eg. for CM roms)
Code:
cd ~/android/rom
. build/envsetup.sh
lunch cm_p6800-userdebug
mka bacon
CM need to download a prebuilt (Termianl.apk). To simplify this routines, I modified the build script from PA to cm View attachment rom-build.zip.
Copy it to the rom directory, type command:
Code:
cd ~/android/rom
./rom-build.sh p6800
After building is complete with no error, the rom will be output to ~/android/rom/out/target/product/p6800.
3. What can we do? :laugh:
3.1 Kernel
Since Samsung provide the complete kernel source, working on kernel would be comparatively speaking much easier.
When we say kernel, we mean the boot.img or zImage which already include the initramfs. This image will be flash to the /kernel (/dev/block/mmcblk0p5)
Hardware and flags are defined in defconfig inside <kernel dir>/arch/arm/config. It is the Linux standard.
3.1.1 difference between stock kernel and the kernel in custom rom
The main difference between the two kernels is the location of kernel library modules. Libray modules are mainly for network and storage drivers. By building them as modules, they can be stoped and restarted in case of critical errors.
Stock kernel put it in /lib which is part of the initramfs. We need to do extra steps to manually copy them to the initramfs after the first build and rebuild again. If you want to build the stock kernel, there is a very good tutorial.
Custom rom put the kernel library modules in /system/lib. Thus boot.img need to match those modules, otherwise they will not work properly.
For custom roms, which defconfig to be used is defined in device tree.
eg. For p6800, in the file device/samsung/p6800/BoardConfig.mk. There is the line:
Code:
TARGET_KERNEL_CONFIG := cyanogenmod_p6800_defconfig
It specify which defconfig file for the kernel
I wrote a View attachment build-k.zip scirpt to simplify the building of kernel alone. Copy it to the rom working directory (~/android/rom)
eg. For p6800, type command:
Code:
./build-k p6800
New boot.img will be output to the same directory as rom if no error.
3.1.2 Add/modify O/C, U/V, GOVERNORS, hardware drivers, etc.
As mentioned in 1.2, we can copy/modified the source from i9100 and n7000 kernels. For example, Dorimanx and Slyahkernel provide many useful code for us. The source of i9300 from Samsung may also provide some drivers update (eg. Mali)
Ref: Exynos4210 cpu menu., Mirror download
3.1.3 Default Orientation
Why the incall screen always landscape?
Many apks assume the default orientation is portrait but our tab's default orientation is landscape. It is a kernel behaviour so that recoveries (including the stock 3e recovery) are all in landscape.
To avoid this odd behaviour of apks like inCall screen, changing the default orientation in kernel is the ultimate solution.
It is already in my do list for a long time but trying to keep up with the android plaftform already occupy all my spare time...
I already have some idea how to do. Anyone interested to help on this can PM me. Already fixed in the platform
3.1.4 Update the kernel source
The existing kernel is base on Linux 3.0.x. It is outdated but I don't think Samsung would bother to update it. I had tried starting with the 3.4 source from Google but don't have enough time to carry on. I have filled some drivers already. Will take another shot later if I have time...
Anyone have experience in Linux kernel are welcome to help. No more guides are there, this would be a great challenge but fun!
3.2 device tree
Every device requires a device tree which:
a) Specify the hardware
b) define some overrided library. (eg. sensor, camera)
c) provide the extra files to be put in the initramfs. (init.<device>.rc, fstab.<device>, etc.)
If there are a few models variants, common parts would be put in a seperate common device tree (eg. smdk4210-tab for our tab). In this way, changing can be made once for all variants.
Most of the work on porting for a specific ROM would be on the device tree. Same as the kernel, we can get some update by modifying from other devices. CM's device tree for i9100, n7000 and i9300, etc. With a good device tree, we can port to any ROM.
3.3 Bluetooth support after 4.2.
In 4.2.2, I changed the source of framework, system_core, phone apk and device tree to work with bluez. It was a huge job! Hundreds of lines had been changed. Many files are replaced. It was quite clumsy but was the only way then. This way may not work for 4.3 onward.
Here are the details of both stack:
Bluedriod : http://source.android.com/devices/bluetooth.html
Bluez : http://www.kandroid.org/online-pdk/guide/bluetooth.html
3.3.1 We may modify the bluedroid to support our chip.
3.3.2 Working on the bluez support. I'm trying now.
　　Bluez5 is OK now. See my thread: How to port Bluez to Android 4.4
3.4 Recoveries
With the device tree and kernel, we can build the recovery from source. CWM would be a side product of CM roms and TWRP has a tutorial.
The same View attachment build-k.zip script can be used to build recovery alone. In the rom working direcotry, to build recovery only
type command:
Code:
./build-k p6800 recovery
With no error, recovery.img will be at the same output directory as rom.

Local manifest
https://github.com/danielhk/local_manifest
All model share the same local_manifest.xml

Thanks!
It nice to see someone interested in our development!
I have look into your changes briefly.
1. Some changes in media which I'll leave the user to decide. I rather keep the builds as genuie as possible.
2. Some of them are new commit of the original source which will automatically updated in a sync.
3. I forgot to upload a few minor projects to github.
One of which was android_build which will include the files like hciattach building from source. If you study the source of exteranl/bluetooth/bluez, they are there. That means it might have update later. No need to add as a blob.
Actually the best way is including them in PROJECT_PACKAGES section of the device.mk. It would have the same result without touching the original source. Less touch to the original source means fewer conflict later. I was caught up and did't have time to tidy up everything so I leave it there. Also, files from bluetooth should be put in the smdk4210-tab device tree. All model share the same source.
vendor_pac should be upload to official PAC's git. They already gave me an account but they use Google+ which I have trouble to login here. I was working on a job and I hadn't follow up. Now I'm working on 4.4 which PAC haven't release yet. So I put aside first.
You probably didn't have to waste you time if you PM me first.
Everytime I upload to github is a challenge, it always break before complete. I have to monitor it from time to time. Annoying! So I can only upload once a while when everything is ready...
To be honest, I really don't have time to keep up with the old source. The new ports already occupy all my spare times. With limited resource, I can only focus on major issues. Bluetooth after 4.3 is my first priorty. If it can be done, means we can go much further.
If you are interested, you may pick one of the thing I mentioned in this thread to start. Wifi-tethering or the vendor ril library is needed too. You may try it in 4.2.2 first. See what you are good at and interested to. PM me or post again if you have any questions and/or suggestion.
Thanks again for your effort.

Thanks to you Daniel for your immense effort on detailing all this! I'm far from a dev status like you and @UpInTheAir. But my support will always go to you developers. Both of you has done an impressive work for an outdated hardware and keep us happy with your Rom and Kernel. Again, thanks a lot.

Thanks, all hail daniel_hk for this!

Daniel,
I can only thank you for all the work he is having to keep our equipment (62xx, 68xx, TXX) alive and really Kitkat will give a new breath, for even in an experimental state already see how the device works smoother. A feather can not help, but I'm looking forward to seeing this in functional status.
As a suggestion, I honestly do not know the procedures, but it would be interesting to ask an official support OmniROM (ROM promising, others liked) and CM. The Galaxy SII has the same hardware, in which the use OmniROM and this magnifies the ROM. Maybe they (Team OmniROM) may offer official support or at least help in these matters!
I'm almost begging for support OmniROM, and Entropy512 (http://forum.xda-developers.com/member.php?u=591147&nocache=1&z=3487892739940434) Kindly reply me: "Someone who is working with one of Those devices and has it working needs to submit it. "
Sorry for my english

Hi Daniel,
Whe I try to repo sync, I was stopped by the error:
"fatal: Couldn't find remote ref refs/heads/cm-10.2"
"Cannot fetch danielhk/proprietary_vendor_samsung_smdk4210."
I was trying to build a cm-10.2 version.
I checked your repository and the folder was right there.
I am new to building android rom. There must be something obvious that I missed.
Thanks.

I think you get this line from my PAC manifest.
That was base on cm-10.1, default is cm-10.1. If you take a look of the project danielhk/proprietary_vendor_samsung_smdk4210 on github, you will find only one tree cm-10.1. cm-10.2 can use the same tree. I'll find time to update it later.
When you build cm-10.2, default tree is cm-10.2. The line without a revision will assume the default. That's why you can find it.
Your solution: Add the revision=cm-10.1 at the end of the project.
Code:
.... danielhk/proprietary_vendor_samsung_smdk4210" revision="cm-10.1" />
Good luck!

Thank you for your help. Working on it. Its a big learning curve for me.

I made up to now the most progress with Ubuntu 13.04 64bit version building the cm 10.1 version.
With Ubuntu 12.04 and 13.10, I have been stopped much earlier than on 13.04.
Now I encountered the error below when running build-k p6800:
target thumb C++: libstagefright <= frameworks/av/media/libstagefright/ACodec.cpp
frameworks/av/media/libstagefright/ACodec.cpp:53:24: fatal error: sec_format.h: No such file or directory

I downloaded the folder that contains the sec_format.h file from https://android.googlesource.com/device/samsung/crespo/. But It is not clear to me where to place the folder.
Thanks.

Not much I can tell. You have to provide the manifest.xml and local_manifest.xml if exist. And device tree changes if exist.
1. build-k is for kernel building only. frameworks_av seems not relevant.
2. crespo is another device. Not the right way to get missing file there.
3. With proper settings and manifest, Ubuntu 12.04 to 13.10 (which I'm using) have no apparent different for building.
If you are building cm-10.1, it is mature. No way there is missing file.
With no other info., I guest there is something wrong with your manifest or device tree. Mixing version projects, wrong flags in device tree, etc.
You might need more reading on what is device tree and manifest first.
Good luck!

Hi,
can you help me with integrating device to manifest.xml? I think there's the problem because everything runs fine until I write luch cm_p6200-userdebug, becuase it shows me that the device isn't found and in /android/rom/device, there isn't any folder called /samsung/p6200. I did everything by the guide, I only changed the local_manifest device info to p6200, because I own it. I'm using Ubuntu 14.04. Thanks for your help.

Not much details. next time provide detail. At least, send me your local_manifest.xml. It is definitely the source of your problem. You haven't tell which cm you built too.
I don't know what's wrong because I can't see anything in your side.
But I can tell you that device tree of p6200 didn't download. Check the typings of your local_manifest.xml. It should match the one in github.
Good luck!
TO ANYONE, YOU HAVE TO PROVIDE DETAILS. OTHERWISE, I DON'T KNOW HOW TO HELP!
I really don't have time to guess. You have to forgive me if I ignor your post.

Okay, sorry for it, I didn't know you need it. I want to build a Cm-11. I looked at my local_manifest and I think it's correct. Here is it

edify question for our 815's
Taken from one of your script's
mount("ext4", "EMMC", "/dev/block/mmcblk0p9", "/system");
Installing a .txt into sdcard0/data through .zip in recovery.
I used linux command to find paths for each of the memblocks - but didnt know which path, partition, I am looking for here. /system /userdata etc UHHHH
so to mount to the "sdcard0 /data"directory to install a plain .txt file would be ???
mount("ext4", "EMMC", "??????????????", "/data");
also can I call "/data" anything - like "/datadog" - since this is just a reference to a mount point and is temporary?
One other quicky
First I found this in an edify tutorial -
"/system partition is automatically mounted. this command is needed when you need to mount another partition beside /system or in any condition when recovery mode failed to mount your system partition. the system's location is /dev/stl9, cache /dev/stl10, and data /dev/stl11 (all partition type commonly rfs, will be differ if you have custom kernel or rom)."
since this is a custom rom does /system still auto mount - meaning in ref to to your code above - was it unnecessary but probably good practice or because this is a custom rom there are changes that move the location for /system. I noticed that " the system's location is /dev/stl9, cache /dev/stl10, and data /dev/stl11" was not in the memblock paths??
Start my intro to kernels tomorrow - Oh boy
Off subject - I knew Brazil - tough break with the injury though. Next wins - Argentina and Costa(CoastBaby)!! Going to bed now 6:00 AM WHAT.

I don't know what's your objective.
Some points to note:
1. command in updater-script use the function defined in updater-binary. Which are not necessarily a Linux executable command. These commands only valid in the updater-script.
2. You can only mount to an existing directory (mount point) which has not been mounted before. The mount command in Linux is a shell command which is executed by /bin/bash.
3. /system is mount by init following the sequence in .rc files. In recovery, a program is running to provide the interface for I/O. It doesn't require /system partition.
4. No matter which rom (stock or custom), the content of /dev are defined in kernel. Partitions info. is read from the PIT (partition info. table). Kernel will initialize the device at boot accordingly. They are similar to a harddisk partition.
5. our tab has emulated int. sdcard. It is part of the /data, at /data/media.
Hope these might help

earlier question simplified
My problem is with the mount command in a zip file to be used on our Carbon ROM partitions.
My goal is to make 4 different .zip files that can be installed with the recovery software. Each zip places one (the same) simple.txt file into a different folder then the previous zip did.
After I install the 4 zips I should be able to use my file manager app to view the simple.txt in each of the following folders
/sdcard0/data so the ????????? in => mount("ext4", "EMMC", "????????????", "/NAMEOFMOUNT"); would be ==>
/sdcard0/Download so the ????????? in => mount("ext4", "EMMC", "????????????", "/NAMEOFMOUNT"); would be ==>
/Root/data so the ????????? in => mount("ext4", "EMMC", "????????????", "/NAMEOFMOUNT"); would be ==>
/Root/system so the ????????? in => mount("ext4", "EMMC", "????????????", "/NAMEOFMOUNT"); would be ==>
This should give me what i need to fill in what I am missing on understanding this.
Thanks - I hope that this understandable
Off subject - Argentina taken care of biz - Costa is dead to me - Next winners Argentina and Germany

Just about there
6GB with intel I5 -1TB- is now setup as a dual boot with Windows 8.1 and Ubuntu 14.4. All the packages are installed etc.
My linux flavor is ARCH or Manjaro (arch based) - Not a big fan of unity, but since I did not want any pitfalls for support reasons I will use Ubuntu for now.
I now have a descent grasp on GIT and repo, as well as installing cyanogen on one supported device. It would appear that to install on our device any of the custom roms I would just need to provide a local manifest with the proper projects.
I am a little fuzzy on a few things but I think if you could please post two (i815's) local manifest's for two of our newer kitkat roms say Omni & Slim I should be able to figure out my answers or at least narrow down my misunderstandings to exact questions.
Thanks
All Hail GERMANY - - that final game was a real snooze fest.

Guide: How To Build AOSP 4.4.3 From Source With Linux Mint 16 - Nexus 5 KTU84M

Guide: How To Build AOSP 4.4.3 From Source With Linux Mint 16 - Nexus 5 KTU84M
Important Note: Do not use Linux Mint 16 KDE to do this guide. Removing the old Java will seriously mess up your desktop and programs menu. This guide has been tested with Linux Mint 16 Cinnamon and Linux Mint 16 Mate.
Link to PA Gapps: http://forum.xda-developers.com/showthread.php?t=2397942
Link To SuperSu: http://download.chainfire.eu/supersu
Link to zip of completely unaltered build of AOSP 4.4.3. https://drive.google.com/file/d/0ByOOg6Qw8gHZMXBWVDRyVmVuRWc/edit?usp=sharing
I started this guide as I could not find a step by step detailed guide to build a stock AOSP from source with Linux Mint 16.
All the steps should work in Ubuntu but I haven't tried so not 100% sure of that.
All this assumes your phone is already unlocked.
Here goes:
Important note: Anything that is bolded text other then section titles are command line entries that are done in Terminal in Linux Mint. I thought it would be simpler to do it this way then say 'in Terminal' for every entry.
First we need to remove Icedtea Java or OpenJDK.
In Terminal: sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
Then in Terminal: sudo add-apt-repository ppa:webupd8team/java
Next: sudo apt-get update && sudo apt-get install oracle-java6-installer
Be sure to accept the licence agreement to install java when it prompts you.
Next: sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 libc6-dev lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 lib32z-dev libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc readline-common libreadline6-dev libreadline6 lib32readline-gplv2-dev libncurses5-dev lib32readline5 lib32readline6 libreadline-dev libreadline6-dev:i386 libreadline6:i386 bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev lib32bz2-dev libsdl1.2-dev libesd0-dev squashfs-tools pngcrush schedtool libwxgtk2.8-dev python
Follow this with: sudo apt-get install -f
This should fix any dependency errors.
Now: sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
Next download the SDK Tools For Linux x64 from this link. https://developer.android.com/sdk/index.html
Then: cd ~/Downloads
And: tar -xvf android-sdk_r22.6.2-linux.tgz
or tab the latest 'android-sdk_xxx.tgz file it they update it and it is a newer version then the one I downloaded to do this.
You can rename the android.sdk_xxx.tgz folder you extracted to SDK.
Then: cd ~/Downloads/SDK/tools
Next: ./android sdk
It will show you the tools that can be installed, just install the highest version API of 'Platform Tools' and 'Tools' for the latest android version '4.4.x' it shows.
Make sure you install the repo tool, in Terminal: mkdir ~/bin
Then: curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
And: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
Now: sudo chmod a+x ~/bin/repo
Now sudo nano ~/.bashrc
Add this to the bottom of the text: export PATH=~/bin:$PATH
Then hit Ctrl-O and enter, it should say it saved the file followed by Ctrl-X to exit.
Then restart bash: source ~/.bashrc
Now lets Initialize the Repository for GIT configuration
First : git config --global user.name {Your Name}
Then: git config --global user.email {[email protected]}
If you have not registered with the GitHub website just doing these two steps works fine.
If you have registered with the GitHub website create a file called .netrc in your home directory, add your GitHub password to it with no spaces on the first line and change the permissions to '600' or you will have to continually authenticate when building the source.
In Terminal:nano ~/.netrc
Then add just your GitHub password (like I said you only need to do this if you have registered with GitHub).
Then 'Ctrl-O' and enter and it'll say it saved it, then 'Ctrl-X' to exit nano.
And: chmod 0600 ~/.netrc
Now: mkdir ~/AOSP
Then: cd ~/AOSP
Now you get the source code etc: repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.3_r1.1
Followed by: repo sync -j12
Use repo sync -j12 for a quad core CPU or Intel I5 or if you have say an quad core I7 with 8 threads you can use repo sync -j24 to speed things up etc.
I have a I7 3930k with 12 threads so I used repo sync -j36. This gives you three threads per logical CPU and speeds things along quite well.
It may take several hours for the sync to finish.
After the sync finishes go to https://developers.google.com/android/nexus/drivers#hammerheadktu84m and download the KTU84Mdrivers (binaries) for the Nexus 5.
If you have closed the Terminal after the sync remember to first do this when you reopen it: cd ~/AOSP
when you open Terminal again before doing the cp and tar commands.
In Terminal: cp ~/Downloads/broadcom-hammerhead-ktu84m-175c1204.tgz ~/AOSP
Then: cp ~/Downloads/lge-hammerhead-ktu84m-716c9c42.tgz ~/AOSP
And: cp ~/Downloads/qcom-hammerhead-ktu84m-06019566.tgz ~/AOSP
In Terminal: tar -xvf broadcom-hammerhead-ktu84m-175c1204.tgz
And: tar -xvf lge-hammerhead-ktu84m-716c9c42.tgz
then: tar -xvf qcom-hammerhead-ktu84m-06019566.tgz
They should be the file names of the binaries for KTU84M that you are extracting but if for any reason the file names are different use the Tab key and tab the correct names in after 'tar -xvf'.
If the names ARE different I'd really check to make sure you downloaded the correct hammerhead binaries.
Now also in Terminal: ./extract-broadcom-hammerhead.sh
Then: ./extract-lge-hammerhead.sh
And: ./extract-qcom-hammerhead.sh
Hint: It will show you a really long licence agreement for each binary that you scroll by hitting the Enter key that takes forever to scroll one line at a time, it has 8 sections and several subsections. Hold the Enter key until you just get past Part 8, section D of the licence and stop there. Now hit enter a few more time one key stroke at a time until you finish Part 8 section E and see the 'Type 'I ACCEPT' to agree to the licence.' and type I ACCEPT If you just scroll by holding the Enter key all the way to the bottom of the licence you'll get an error you never accepted the licence. Then close Terminal.
Building the Sources
Now open Terminal: cd ~/AOSP
Then: . ./build/envsetup.sh
Now to select the type of device we give the following command: lunch
Choose: 9. aosp_hammerhead-userdebug
by entering '9' or whatever number aosp_hammerhead is after your enter the 'lunch' command (it was number 9 on mine).
Now: make -j12 for a quad core cpu or I5 or make -j24 for an I7 etc.
With your phone connected to your USB cable and the PC: adb root
Then: adb reboot bootloader
And: cd out/target/product/hammerhead
Lastly: fastboot -w flashall
If you get an error on the 'adb' and 'fastboot' commands do these first:
sudo apt-get install android-tools-adb
And: sudo apt-get install android-tools-fastboot
If you get an error when you fastboot -w flashall to do with a '-p' flag needed or 'android-info.txt' is missing it means you forgot to to the 'lunch' command before building the source. Go back to the 'Building The Sources' section.
If you already have a custom recovery installed like TWRP and would rather build a zip file to install with the recovery rather Then flash it in adb instead of make -j12 do: make -j12 otapackage
In the /home/"yourusername"/AOSP/out/target/product/hammerhead you have an aosp_hammerhead-ota-eng.___.zip file to flash in your custom recovery.
You will need to wipe/reset data in recovery before flashing it and re-install all your apps etc.
Installing Custom Recovery, Rooting and Google Apps
If you want to install a custom recovery download TWRP http://techerrata.com/browse/twrp2/hammerhead
Rename the file in Downloads to recovery.img
Then in Terminal with your phone connected by USB to your PC: adb root
And: adb reboot bootloader
Then: cd ~/Downloads
And: fastboot flash recovery recovery.img
Use the volume buttons on your phone to scroll onto "Restart Bootloader" and hit the powerbutton to select it. After the bootloader reloads, use the volume buttons to scroll to "Recovery Mode" and hit power button again to select it. You should then be in your custom recovery.
If for any reason you get a red android and no recovery just boot into fastboot mode again and reinstall the recovery.img.
And finally, to root your phone download SuperSu http://download.chainfire.eu/supersu and install the supersu.zip in recovery mode.
Download PA GAPPS from here http://forum.xda-developers.com/showthread.php?t=2397942 if you want the zip to install Google Apps in recovery.
You now have your own rooted vanilla AOSP you compiled yourself, congrats!
P.S. Very likely a good idea wipe/reset data in recovery and start with a clean install, you'll need to install all your programs and stuff anyways I'm sure.
P.P.S. I also installed the Xposed Framwork apk from this link http://forum.xda-developers.com/xposed/framework-xposed-rom-modding-modifying-t1574401/post24267797 so I could install the Advanced Reboot Menu and some other useful mods.

Hi man great tutorial.
I followed your tutorial exactly and it compiles very good and everything works great with flashing it to device to.
I start the rom and everything is working but then if i reboot i get wrong date and time for 20sec and it goes back to current time and date.
but i get like 10 notifications from all my google apps and it very anoying. and google now dont work till it gets synced.
i thougt it was my build that had issues but i flashed your rom that you had compiled and it has the same issues.
Did y have that issue?

No, I've never had that issue. Did you wipe/reset data in recovery. If you never you need to do that. If you did I would try and do it again, it might fix the issue. You'll have to re-install all your apps etc. when you do though.
Also you can try to flash the zip I have to download in the OP, it is a completely unaltered stock AOSP build. DO wipe/reset in recovery before you do and you'll have to install the recovery in the guide to flash the zip.

Edit: Sorry, just now saw you flashed my ROM. The wipe data should fix it though.

Of course i wiped before flashing. The thing is it works on first boot. time and everything no notifications from google apps but as soon as i reboot time and date resets and i get 10 notifications from my google apps sayin time and date error and syncing problem.
I decided to make a clean repo sync again by removing everything and start from the begining. Let ypu know how it goes.

I'd try wipe data again and I checked the Date/Time settings, I have 'Automatic date & time' and 'Automatic time zone' enabled. If it does it with my zip and your sync I doubt it is the build that is the trouble. You also might want to try disabling the auto time and date and setting it manually, it might be it is taking a minute to sync with your cell provider, hence the errors. Manually setting the auto time zone as well.
Also you might want to try a different Google Apps package from the link I provided. I use the micro one then if I have to add anything I just do it by Google Play.
Found this link, I'd try the flashable zip a few posts down or manually editing like one guy suggests.

Thank you for that. But its just a patch to fix. How come its broken if it comes from google repo ? :S
i compiled CM11 and no time issues there.

This is a perfect guide. Thank you VERY much.

The guide has been updated to the KTV49L build which has several bug fixes from the old build. I'm not sure if the date issue has been fixed but if you want to try to build AOSP again just letting you know it is an option.

You need to delete your /home/yourusername/AOSP and /home/yourusername/bin folders you made.
So do: rm -rf ~/AOSP
And: rm -rf ~/bin
Then just:
Make sure you install the repo tool, in Terminal: mkdir ~/bin
Then: curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
And: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
Now: sudo chmod a+x ~/bin/repo
Now: mkdir ~/AOSP
Then: cd ~/AOSP
Now you get the source code etc: repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.2_r2
Followed by: repo sync -j12
Use repo sync -j12 for a quad core CPU or Intel I5 or if you have say an quad core I7 with 8 threads you can use repo sync -j24 to speed things up etc.
I have a I7 3930k with 12 threads so I used repo sync -j36. This gives you three threads per logical CPU and speeds things along quite well.
And the rest following that. You do not need to do the other steps though, but the recompiling and build you do so it takes some time.

Thanks alot my friend. Just did as you said. And i can see in settings that it KVT build but the time issue is still there. I dont get it at all.
im pissed.
its like building a car and the wipers don't work.

Sorry, only fix I know is the patch in the link I provided earlier. I have read of other people with the AOSP build have that issue, it's in that link. I don't why it never affected me, might be the settings I use for Time/Date but I've had zero issues that way.

Yeah i would like to share the rom with friend and it would not be nice if the time resets and getting those notifications error all the time.
Thx alot

i've downloaded this(http://forum.xda-developers.com/showthread.php?t=2585828) build environment from xda so i can start building a rom for my phone and, if i'm not mistaken, i can start your tutorial from the github part right?

I'm not 100% sure t'll work in Xubuntu. I know when I removed the old java in Linux Mint KDE it really messed up the programs menu, even Terminal itself was removed from it. But if it doesn't mess anything up it should work I believe. or just install Linux Mint 16 Cinnamon or MATE in the virtual box instead of Xubuntu, then it'll work I'm sure. Might build much slower though running in a virtual box. You'd have to do everything from the start of the guide, the linux installed in a virtual box is just a clean fresh install of any linux just like a regular new install on any PC.
Hope that helps.

when I had the galaxy s I tried to create a buildmachine but even following every step, there was always something missing, that's why i gave the vm sugestion.
i'll try with the vm but if it doesn't work i'll start from scratch...
thanks
ps: it's a virtual machine but it is running in a i7 with 4 cores and 8gb of ram dedicated to it(if needed i can go for 10gb)

By start from scratch I mean you just do all the steps in the guide on the fresh virtual machine install. The only time you don't need to do all the steps is if you've done a build and need to do a second build like I did for my Nexus 7 after my Nexus 5 or when the repos update to a new version after you've done a build already. In post #13 it says what to do if you're doing a second build. If it's your first build or a new install of linux or a new virtual box install of linux do all the steps right from the beginning of the guide. Hope that clarifies things.
P.S. Should be pretty fast with your virtual machine but it takes me close to an hour to download the source from the repo then another hour to actually build AOSP with a 6 core 12 thread I7 3930k and 32 gigs of ram.
P.P.S. Sorry for the late night responses, I get home from work around 11 p.m. EST and like to game and stuff a bit before I do other things. Really busy at work, not much time to check here very often.
