I really dislike the "chef" moniker when it comes to Android, since we are more of an open-source community. I think it implies a "file pusher" mentality. But then again, I am biased against proprietary versions of Android like Sense, so feel free to disregard all of this.
Here's my advice for those looking to make their own Android ROMs.. Stop. Write an app or two first, learn how the system works from a developer standpoint. Learn some Java. Read the developer documentation. Learn how to use Git. Then learn how to build AOSP from source. Read the porting guides, and learn how the build system works (the links below have almost everything you could possibly want to know). Now try to put your new found skills to work on enhancing the platform by writing code or making theme overlays. And share! And put that **** on your resume. There is a *ton* of information out there but any kind of "step-by-step rom cooking guide" is going to be a complete fail- it's too broad of a subject.

How To Create A Community Rom

Hey recentrly i made the " b6gsix gude for noobs: how to theme a rom " and one reply from a guy said SO YOU ARE TRYING TO MAKE A COMMUNITY ROM ?
i wasnt but thats sounds nice. ive seen one community rom b4 and i like the concept but im no dev lol so how do i go about doing so?
You don't. Don't hop right into making a ROM. You need to at least know how to program it. Let me quote something cyanogen said:

I'm seeing you're having problems themeing. Understandable - you're new. However, if you can't even theme, you need to just take it slow. Master Android deving little by little until you can write an app - as useful one at that - and can write it well.
As for starting a community ROM - I don't think many people will just hop on it with you if you yourself can't even program the ROM.

Topics and questions regarding compiling AOSP based Roms vs other sources like CM

I have decided to rework the thread to ovoid any confusion as the intent of posting this thread was to ask questions about compiling custom Roms from AOSP source that someone like myself who gained their development experience on other devices that building from pure AOSP code was not an option and are not as familiar working with AOSP. In the past my own experience comes from using and modifying for example the Cyanogenmod source so after attempting to now base my Rom on AOSP this time around with Lollipop have run into a few unfamiliar differences. As each question or topic is addressed I will update the Op. The hope is not only will I find solutions or answers to my own questions but that others in the same position will also be able to find use of the discussions posted in this thread.
Compiling the AOSP source into a format that can be safely flashed using a custom recovery. This was a 3 part question the first was just simply how to compile AOSP in a format other then .img files that can be flashed using a custom recovery without the need of flashing through fastboot or needing to use the adb sideload option.
1, Compiling AOSP into the for of an update.zip.
This was answered in short by know.patience by suggesting to use the “make otapackage” command in place of "make" to start the build. Was also made aware that a few modifications would need to be made to avoid producing an update package that does not use the new block format but instead the old style zips we are most used to seeing.
2, Now can create an update.zip using the “make otapackage” command ran into an issue that by flashing the update.zip produced would in the process replace the custom recovery used to flash with the Nexus Stock recovery. This was answered by Lethargy who suggested and provided a Link for the following commit.
For getting rid of the AOSP recovery:
https://github.com/Lethargy/android_build/commit/48521e167c642db76c9d4f52b1c63f9abc7f707f
https://github.com/Lethargy/android_build/commit/1d9224bd45ef2b4f5601a157de2bfe3bb1c95558
3, Now can create an update.zip using the “make otapackage” and after applying the above commit are now able to flash the update.zip without replacing the recovery Lethargy also provided links for the following commits.
To get rid of the block-based zip format:
https://github.com/Lethargy/android_build/commit/4d458300d935a3a9d893a590286cb578dcf54db2
You'll also want to make sure you have this commit so it doesn't flash awfully slow in recovery (8~ minutes, but only around 1-2 minutes with this commit):
https://github.com/Lethargy/android_system_extras/commit/52f8d5fc3edfacd112827d0a41516c1dc5f4a468
This one isn't required but you may as well:
https://github.com/Lethargy/android_build/commit/242be9ae4f05e3cb1d39d635cac7147ff904700c
Compiling using the AOSP Master branch vs release branches. In following the directions provided on the Google development site are given the command for downloading the source code using the Master branch. Using the Master branch as apposed to a release branch such as android-5.0.2_r1 or lower have found that the source compiles just fine but have run into one issue and just a general question that a little explanation would be helpful for general understanding of the AOSP Master branch.
The issue is that after flashing a Rom compiled using the Master branch everything in the Rom works as expected other than the radio. I have so far using the same exact vendor blobs as compiling a release branch have not had a signal and baseband version is listed under about phone as unknown.
The general question is that the android version listed compiling a Rom using the Master branch is version 5.0.50.50.50.50. In general I have yet to understand what this version number represents and very little to no information available via the Google Box.
Between the both I now wounder if the Master branch is intended for actual use or if so what changes are required so the baseband version is recognized and radio / Ril will work?
Quick Answer:
Google first commits new code into master and then is later tagged with an update for realease so in generall many things can be broken and the master branch is and not intended to be stable so if building from master expect that things will be broke or buggy.
Compiling Rom and Kernel together. For those of us again used to compiling using say the CM code are now used to compiling the Kernel along with the rest of the code. I know it is easy to just compile the Kernel and include in the device tree but for those of us who would still like the Kernel compiles with the rest of the code there is no information available on the Google Developers site for doing so and there seems to be a few differences as have tried just using the lines used in the CM Hammerhead device repository. I have come across these commits from Cl3Kener that should help. Hate posting other developers code but is on Github so is there for the public at large. So far have only tested as is so will update if finding not all changes are necessary or can be modified.

Adding Pre-Built APK's
Seems Sprint users need a few apk's for updating prl and what not that are included into the Stock release but are not part of the AOSP code. For some reason through vendor or even device have tried adding these apk's into the build. First try I created a sprint vendor section and received a few errors untill learning would need to add sprint into a vendor white list found in build. Will post link to file later. After found the extra "Services.jar" I found in the stock image not found in the aosp compiled Rom did copy into the build but the apk's had not. Looking in the other vendor blobs noticed lge adds "qcrilmsgtunnel.apk" so followed the example and even tried just adding the other spk's into lge expanding the list used for adding in "qcrilmsgtunnel.apk" but still no luck. Also have tried adding through the device files for Hammerhead just to get them into the Rom for testing and still no luck. If this was CM or any other Rom not using pure aosp this would have been a 5 minut project so need to do some aditional homework.
Again think this thread could be a good resource for developers who are new to building their Roms around AOSP so wanted to include everything I run into during the process of moving away from using a heavily modified CM based code as the base of my Rom to using AOSP in its place so developers who are or in the same process or for those in the future can use as a resource to quickly adjusting. I have been building CM based Roms like Starship for years and after hours of working on other aspects to suddenly be stumped by these small differences between platforms can be very frustrating.
to the OP:
answer to your first question comes in two parts.
a) use 'make -j# otapackage' will generate a zip that is flashable in custom recovery.
b) if you plan on adding other files after the zip is made, you will need this info here:
https://github.com/android/platform_build/commit/26e6619c37e294fe2ee63aaa759e0ac861775ce8
There are some modifications needed to generate the OG zip files instead of the new "block" format.
Google hasn't released the 5.0.1 image for the N5 but that doesn't mean you can't build it and install it yourself. I'm running it and it seems okay to me so far although I'm hardly an expert.

I am building a customized AOSP Rom I am interested in sharing so was looking for help or direction in creating an update zip that can be flashed in a custom recovery like TWRP. I am not used to compiling AOSP and with the help of know.patience in the first reply am now able to compile an update.zip I can flash in TWRP but in doing so it also replaces TWRP with the Stock recovery. I have still been using the .img files to flash personally but am still trying to figure out how to solve the recovery replacement issue. I still have other features I am adding and testing before I would like to post my work but before I get to that point I still need to figure out my recovery replacement issue. Maybe using the words personal use may have been confusing but at the moment until ready I have only been using my work personally but would like to at some point post and share. I also have work that is not AOSP based I am sharing in the Android Development section but I have been building CM and other source based Roms and sharing for years. This is the first device I have been able to build AOSP and still have a few things to figure out before sharing any of my AOSP based work. I am otherwise not sure why you think these are questions for general Q&A.
I started this thread in Android Development as there was only about 4 posts in this section and I see many AOSP based Roms in Android Development who's developers obviously know the answers to my questions so tried to get away posting there in hope one of these developers could help or like in the first response point me in the direction of a commit before the thread was moved by a mod into this section. Do you think someone in the general Q&A section is better equipped to help answer questions about compiling an AOSP based Rom in the form of an update.zip that can be flashed in TWRP without also replacing TWRP with the Stock recovery?? Would also be nice knowing what changes in the code need to be made in compiling an old style update.zip that does not use the new block format. This would be a bonus but overall not %100 needed as instead of moving files around after the code has been compiled have added init.d support and first have all the files I want moved into a staging directory and then form an init,d bash script to move the files during first boot and remove those that are not needed like this example I used in my CM based version of the Rom I am trying to update for AOSP for 5.0.
https://github.com/Starship-Android/android_device_starship-common/blob/cm-11.0/app-update
https://github.com/Starship-Android/android_device_starship-common/blob/cm-11.0/cleanup
I must seriously be underestimating the knowledge and in general the types of questions being asked and answered in the general Q&A section.
Honestly if not for the amount of times thanked I would think this comment was not so much about helping or community but more about someone trying to puff themselves up by trying to appear important by making decisions about what questions are worthy of being asked but judging by the number of times they have been helpful I am thinking its either a case of not reading or understanding the question being asked or my own inability to express my questions in the proper manor. Either way its definitely not about taking up resources in a section with less than 10 total posts. The frustrating part as a community as I like to believe we are all in is that why I worked on other parts in updating my Rom had expected that at least more than one developer out of all the AOSP based Roms posted in the development section would have helped me with this one part. Its not like I am asking how to be a developer just a resource to help with two simple things I am sure I could have figured out and will most likely still figure out without any help. Overall my thoughts behind posting this question was that why I am working to figure out something a bit more time consuming at least more than one person would be helpful enough to copy and past a commit.
XDA is weird in that with other devices all the developers would join a team and start a shared group of repository’s for one another to use in trying to make the best possible experience and options for everyone. For example in the op I posted an example of hours of work I did showing what libraries are needed by one another just so others could use it also in trying to port as much as possible for in that case the Galaxy Mini. Then with other devices like seems to be the case with the N5 its all about competition and what I am starting to call the smartest person in the room syndrome. Its just a shame there are only 5 maybe 6 threads posted in this section and I think that says allot about the community in general. So many good things could come about if we just tried to be helpful and pull as much knowledge together as we could. Anyhow think its time for ending this rant.

Thank you this is well beyond what I was looking for and don’t worry I make it a point not to send out PM's with questions that can be helpful for others as well. Otherwise would have blown up the AOSP Rom posters in development but thanks for the information.

If you mean "I'll probably ignore you if you try asking for support over PM.", that's part of my forum signature.
If you need anything else feel free to @‬‬mention me in a thread, though.
I reworked the Op to avoid confusion as Mods have been moving the thread around into different sections. I personalty believe these questions are more geared towered development than general Q&A but at least at the moment I appear to be wrong about that. Never know though as in the past one day one of the mods may decide to move the thread back into its intended location but until then I guess these topics will be of better use to general users than developers.

You should include the other commit (https://github.com/Lethargy/android_build/commit/1d9224bd45ef2b4f5601a157de2bfe3bb1c95558) which fixes building since the first one results in "IndentationError: unexpected indent".

Thanks for the heads up, when testing these I also cherry picked a few other things that looked related. Have to double check but may have forked the repository’s from you so would receive credit if anyone decided to look over my repository’s. Well overall my personal Github has been pretty bare as in the past most work was done on more obscure Virgin Mobile devices with only a few developers so we would pretty much create an organization for all the developers to use.

Have 2 other members listed who I had worked with in the past but has otherwise been a solo organization with one of the other members who decided on going with the Moto X and Verizon over the N5 and showed little interest in his 2012 version of the N7 as it was intended for being a Nexus only device line up and the second being my Kernel Guru from a few devices back who mainly joined to help me out with a few things but ultimately what I am getting around to is this is the first time working %100 solo. Have to say without having anyone to bounce off ideas and share findings with things definitely move much slower and take a bit of getting used to. Is also the reason for starting threads like this. Most of this stuff looking in the developer section appeared to be pretty common knowledge but having never worked from pure AOSP before was slowing down other development for about a week just to figure out what seemed like half the community had already known and with what probably took at the most 5 or 10 minutes of copying and pasting commits probably saved me a weekend of sifting through github and testing. I hope by creating a thread like this will be able to do the same for others.
Hi guys,
Anyone manage to fix RIL problems with master branch?
I also build AOSP roms so for sure i will hangout here

Why do you need to odex a prebuilt apk?
Not sure if what you want is even possible.
But if odexing your prebuilt apk is necessary then why not odex it then include the .odex with the prebuilt?

Nothing so far, I downloaded the master and 5.0.2_r1 branches and have loaded both in meld for looking over differences but have not yet identified from the dif between the 2 branches that is responsible for ril working in release branch but not master. Still have allot to look over though still. Still have not found a decent explanation of the master branch to know if its recommended to build from but still just for Knowledge sake am interested in knowing. At first thought maybe apn's but not so sure with baseband also listed as unknown from my Master branch builds.

As far as i know all the patches goes to master branch then from this branch ,if they are ok,is distributed to lower branches.I also didn't find info why is named as 5.0.50.50.I will try to investigate this ril problem

Thanks will definitely update the Op with any findings. Was very surprised to find the thread again as it has now been moved 4 times by 4 different Mods, some bounce it to general Q&A and then is bounced back here by another. I understand its not comprised of the most advanced development topics but with that said is still way more advanced than the topics being discussed by general users over in the general Q&A section. I had just thought it would be a nice one stop place for learning the basics of AOSP development. With the constant moving and scolding messages being received one would think the threads very existence is up there with crossing the streams and threatens the existence of Android development.
@chairshot215 Thank you for starting this thread. Thank you @Lethargy for all of your insight. I like to do my own perosnal builds every once in a while for my nexus devices. What I have observed over the years is that the Master Branch will sometimes have funky version numbers like you have described. One thing to consider is what @malcho mentioned. If all commits indeed go there first before the respective branches(although this may not entirely be the case), then it is likely that some things may be broken in the master branch from time to time, hence the ril problem. I think with the galaxy nexus I ended up running into issues from time to time with the master branch, and from there learned to build for specific branches/tags. For instance, there are times when items within a specific branch will be ahead of master in some areas and behind it in others, as in this link to platform_build for lollipop release https://github.com/android/platform_build/tree/lollipop-release. So with that, it is probably in our best interests to just use specific branches.

Thanks for the response and have definitely learned its better building from branches with a release tag. Still very curious why and how the branches are structured so thanks for the explanations.
Way totally off topic for the thread but landed a brand new SSD and decided to install everything fresh. After everything was set back up and wanted to start building I ran my usual,
-j'grep 'processor' /proc/cpuinfo | wc -l'
a very old habit before fully understanding what number to use after -j so used grep to figure it out based on Googles recommendation. The command did not work so removed the grep and just made it -j4 but also with 0 success. At first just figued I missed somthing setting everything back up and "make" is just not working but wrong again as running "make" command without -j of any number works just fine.
Also tried this with CM12 as I am doing 2 versions of my Starship Rom. One from AOSP and one using CM. Figured AOSP would be special for Nexus users why also having a version for CM I can make most changes by adding a Starship Device Tree could easily port the Rom to any device running CM supported or not.
https://github.com/Starship-Android/android_device_starship-common/tree/cm-12.0
Also found why compiling CM that -j also results in an error
Invalid lunch combo: cm_hammerhead--j4
No such item in brunch menu. Try 'breakfast'
So far have not found anything using the Google Box so figured may as well ask. If have not figured out by now I have no shame in asking questions. Oddly enough that is for things that are probably relatively simple. Took a better part of a week figuring out how to start CM using the Now Launcher and setting up init.d bash scripts for moving around and replacing libs after learning the Gapps package includes libs that will not work so the solution needed to be that the CM Gapps package libs needed to be replaced with either stock or libs pulled after installing the Now Launcher from the Play Store after flashing Gapps and the Rom staring. Also then what if user updates and wipes the system partition after the new and updated llibs have been moved into place. Anyhow point of story is things like this I will just figure out without bothering anyone but for the cant believe I need to stop what I am working on to figure out something most likely very simple and can be answered with very little time spent I have no shame in just asking. Not that someone else’s time is less important but like I have mentioned before is frustrating just after spending hours or days figuring out something asked in dozens of threads is just frustrating getting caught up or loosing momentum and thought processes over something so simple there are little resources available. Also I assume most devs have the same experience when you have an idea or thought behind resolving an issue that once you stop and change direction it just sometimes never comes back and that short time you had I guess can be called an epiphany is gone once going back. Otherwise thats how I justify asking dumb ars questions.

If you're planning on using a kitchen, please don't. Do it right.
CM/PAC/Slim/PA/etc is still in the works for this phone so you'll have to do a lot of leg work. I suggest @r3pwn's repo since he's apparently got a functioning CM12.1 WIP

I really dislike the "chef" moniker when it comes to Android, since we are more of an open-source community. I think it implies a "file pusher" mentality. But then again, I am biased against proprietary versions of Android like Sense, so feel free to disregard all of this.
Here's my advice for those looking to make their own Android ROMs.. Stop. Write an app or two first, learn how the system works from a developer standpoint. Learn some Java. Read the developer documentation. Learn how to use Git. Then learn how to build AOSP from source. Read the porting guides, and learn how the build system works (the links below have almost everything you could possibly want to know). Now try to put your new found skills to work on enhancing the platform by writing code or making theme overlays. And share! And put that **** on your resume. There is a *ton* of information out there but any kind of "step-by-step rom cooking guide" is going to be a complete fail- it's too broad of a subject.

The PDK site is absolutely vital if you are going to work on custom ROMs. Read every single page. Twice. Some of the info isn't up to date, but you'll get a really good idea about what goes into actually configuring Android to work on a real device.

If you don't have very much development knowledge and you don't really wanna learn then just wait. It's going to take a lot of time, a lot of reading, and a lot of work. It's not easy-peasy. Just forewarning.
Depends on what you mean by "functioning". To me, functioning = booting (even if some Core features are not working). With my stuff, WiFi/camera/FM radio does not work, so everything's still a WIP.

Huawei P9 Lite devs

Good day lads,
Disclaimer:
Code:
I don't know if you noticed a thread in the Q&A section that was closed by Matt. While I respect Matt's decision to close it, I find it a very relevant topic... The future of LineageOS for the P9 Lite. Please note that I do respect meticulous' wishes to charge for his work because I know how time consuming it is I wish to firmly express that I do not condone this mentality when it comes to Linux based operating systems.
I decided to make this thread with my little Dev knowledge in order to attract more devs who's willing to put in work on a stable device tree for free in spirit of community and for all to enjoy.
I do not have the Lineage source code at the moment but I will start downloading soon, I do know that I will need help and I encourage more devs/beginners to lend a hand for the benefit of us all.
Please, to begin, post links to relevant tarballs/links/downloads for development purposes, device tree and kernels, anything you've worked on so perhaps we can all work together.
Cheers

Hmmm... The fact that building android ROMs is time consuming is not a good enough reason to request money for OPEN SOURCE SOFTWARE. Yes, LineageOS and android in general are open source, so that's an infraction.
About the collective effort, that's a good idea, but there are no sources from Huawei right now. You need to wait for the Nougat sources if Huawei really gives a dime about releasing them. From that point, it is easier to develop and get stuff working. Until then, good luck working without sources and experimenting stuff. Not to mention that there's no official TWRP as well, and TWRPs posted here on XDA for our devices have specific requirements to get them flashed on your device.

Why do you need to come here with negativity? I don't support meticulous but he can do what he wants with the device sources he took the time to build, heck, he doesn't need to release those sources so I don't know what you're talking about, firstly. Secondly, a device tree can be built, Q.E.D we as a community can work on it together, if they release it we'll just have it much easier.
Note also; I've asked for relevant input and help from the community.
Thanks for your time though.
EDIT: P.S Professional Flasher, have you ever built a ROM before? Because that's my target here, finding people who knows how to fix error and put the tree together

This disussions are undesired here. I know a board where you can discuss that. If you want, feel free to have a look at it. This little Board is very pleased about every enlivenment. Opened a thread over there.
Well, developers do not grow on trees. I guess there are not enough devs here who have the P9 Lite device.
However I like the intention of the thread author. For that reason please try to discuss in a human way.
In the end: I am vers interested in learning how to build custom roms but I can't find a way how to learn it. Does anyone have some good advice?
Updated kernel
Hello everyone, I've recently been working on updating the Honor 5c kernel to 3.10.105 and so far it seems to be working fine on my P9lite, LineageOS 14.1. It's based purely on stock, with one or two commits borrowed from Meticulus' kernel repo, so it compiles without errors.
Since this is a new account, I can't link my repo directly, you can find it on my github profile, Avsky.
I'll be making my own additions to master branch, while stocklike branch will contain only fixes and kernel updates.
If somebody would like to test them, you can get the boot image from releases tab on github. Stock kernel hasn't been tested, mind you, always keep a backup!
Also depending on how much time I have, I might get started on bringing OmniROM to our device (I'm really missing it). I'm just a college student though, so it might never see the light of day, any help is much appreciated.

Hello, I tried your kernel on AOSPA MM but I couldn't get the proper unpacked zImage. I got only 9.7 MB gzip which contains the 22 MB Image but I couldn't extract it.
Could you provide the zImage?

That zImage looks like the same I got from unpack. For some reason it won't boot when I repack it with my ramdisk.

I repacked and uploaded my image with ramdisk from your latest AOSPA, could you try it? Sizes varied a bit, I've used my abootimg config with SELinux changed to permissive, as that is the case in your image.

Glad to hear it! Your images seem to be using uncompressed zImages, while in stock ROMs they're gzipped, seems like unintentional change somewhere in your build process.

Yeah you're right. I just checked it and I am copying Image instead of Image.gz. Seems like it's only a 'cosmetic' issue because it runs anyways.
Great news guys, my sources now compile with latest Linaro toolchain. The kernel actually barely needed any fixes, but I'm not releasing anything prebuilt yet, since I have no idea what impact on stability my hacks might have.

Perhaps reading through GitHub commits, checking the code and see whether or not you're really interested. If you're using a Linux distribution which I strongly advise, learn bash scripts first - it's easy and self explanatory and from there you will get basics of directories and calling up files.
Goodluck

[ABANDONED] MIUI 8 For Huawei P8Lite ALE-L21

--FOR MORE INFO AND NEWS ALWAYS CHECK MY LAST REPLY!--
Thanks for understanding!
PROJECT IS ABANDONED.
Regards,
Holy ****, finally. I cant try it out for my self cause i need to leave to malta tomorrow but i can try it later
MIUI Rom, finally!!!!
I hope they fix the bug as soon as possible
Again, the ROM is NOT bootable, I need logcats from you to fix the problem, hopefully.
So don't expect this to boot.
Thanks for understanding!
Try to take a look here Logcats
I hope to have helped

That's all I've found and that can be useful for both this Rom and others that you will develop.
Thank you, but I know how to dump logcats. I asked you if you could provide me some logcats of the rom not booting from your device and send me.
Thank you.

And if you would copy libGLES_mali.so to /system/lib64/egl?
Would it work?
Thank you for your logcats. I will see what I can do.
How does it go with progress?
Should boot if you use custom kernel and copy&replace blobs
I am giving up on trying to fix that error message. I am trying to build AOSP 6 and then try again patchtom, hopefully I won't get that error.
I know how to get miui booted, making aosp is not enough, there is changes you need to play with them like .rej files and boot.img too experienced on my old s2 plus i9105p. as I got stuck at animation boot.

MIUI ports were one of the most time-consuming ports. I'm not sure how does it look like today but I'm pretty sure it's identical to how it used to be. First you had to modify the ramdisk and then patch all java resourced and with a bit of luck you get bootable rom.
I'm really sick of seeing all those roms all based on 1 device tree which is not even fully functionall yet. People keep making "new" roms but all are actually the same, all have same list of non-working features. Just compiling different android distro with same device tree over and over.
XDA used to be place for original work and for people who put effort in their projects. Now kids keep spamming dev threads with copy&paste roms or useles threads.

Yeah. We have like 2 developers(one is a team) On this device. Haky and OpenKirin. And 6 "different" ROMs that all work the same, with the exception off the nougat FOMs, which have even more bugs.

I know man, I wasn't talking about you. I was talking in general. I know you're doing god work, despite I'm not developing anything since a long time I still read forum and follow what's happening.
Like @Vinnipinni said, 2 guys and 6 "different" roms. But all working the same.
Back in times people were more likely waiting for stable CM/AOSP before compiling bunch of other distros. Now it's just mess.
I really wish I could go back to developing for android devices, especially now when I have programming knowledge and experience.
