Android Auto ROM? - Android Auto General

I've looked around on the web, and I can't seem to find an answer to this, but what exactly IS Android Auto? Is it a special ROM of Android? Is it an app? Is it specialized Firmware?
I want to build my own carputer, and I can replicate pretty much everything I want EXCEPT the ability for the headunit to interact with my phone to handle SMS and calls. I know that there are a lot of aftermarket headunits that can do this, but again, I want to build my own (fairly certain I can do so for cheaper). Ideally, it's a matter of building my own and customizing the ROM to handle my hardware, but I haven't been able to find any information suggesting that this is the case. Does anyone here an idea?

Hi mate, I'm in same boat, I have got nexus 7 2013 , everything will be worked out except phonecalls or text messages...
All I need is nexus 7 to have a bluetooth headset profile... I.e. nexus 7 acting as a Bluetooth headset.
If you can create rom or modify rom there are already source codes and system dumps available
Other people have made it and made Chinese android head units with this Bluetooth capability...
Basically bluez.org also has complete Bluetooth source code that can be added to any rom
I can send you link from PC if you want to see the source code of already working ROM of a Chinese head unit
I wish I knew programming etc I would have made nexus 7 act as bluetooth headset...

FM Radio

Does anyone know which FM Radio chip the Note has ?
My guess is a Silicon Labs dedicated FM chip, as is in the Galaxy S and S2 models. Perhaps it's accessible via /dev/fmradio.
If you call 5" a tablet, I think this Note may be the first major manufacturer tablet with officially supported FM radio. There are some esoteric Chinese tabs that support FM, and the original Dell Streak 5" has FM, but was never officially supported.
Can someone try the FM TwoO app and report if it works ? : https://market.android.com/details?id=ca.gc.crc.fmtwoo
I am also very interested to know if my FM app runs on this device, rooted or not: https://market.android.com/details?id=com.mikersmicros.fm
Thanks !
Someone has sent me debug logs (Thanks !) so I don't need any more. This device does have a Silicon Labs FM chip, and it appears that my app is working, although the emailer didn't say. He set Menu->Settings->Audio->Method to "Samsung2". It's possible "Samsung" would also work on a stock device.
Other than my curiousity about FM TwoO working, my question is answered. I'm tempted to close this thread, since I'm not here to try and promote my app, but I'll leave it open for now at least, should anyone want to discuss FM on this device, as appropriate for a Q & A forum. (?)
BTW, I get the impression that the Samsung FM app is better than other stock FM apps. It supports RDS, and I think AF, and on this device at least it seems to support recording, which I'm not sure any other FM app does.
hello
as i was already searching for any alternative FM Radio app that does not stream from the internet as there are millions and millions of streaming apps out there it was impossible for me to find them in the android market.
I liked the alternative radio app for my old Windows Mobile Device.
Now i own a Galaxy Note and tried the two apps
FM TwoO and Spirit FM Free.
It finds Radio Stations etc. But i get no sound from both apps.
I think i tried every possible sound setting.
I have Root on my Device but everything else is stock.
Is it supposed to not work on the Stock rom or can i help you with something like a debug output so your app can work on this device?
Just tell me

Hi. There are almost no alternative FM apps for Android because Google refused and still refuses to provide an API. Just about every phone and chip manufacturer does FM differently and keeps their methods secret so it requires reverse engineering, which is very difficult and time consuming.
The CyanogenMod and MIUI ROMs have their own FM apps (for some devices only). FM TwoO works on some Galaxy S/S2 stock ROMs. My app Spirit tries to work on as many ROMs and chips etc. as feasible.
Now i own a Galaxy Note and tried the two apps
FM TwoO and Spirit FM Free.
It finds Radio Stations etc. But i get no sound from both apps.
I think i tried every possible sound setting.

Finding stations etc. is the first obstacle. I'm happy to hear this works OK.
Sound is always the second obstacle; so many phones do this differently, even otherwise somewhat similar phones as Galaxy S and S2.
If the Audio Methods Samsung and Samsung2 don't work, we need a new Samsung3 method I guess. I think the S2 has the same issue. If I examine the stock FM app, and perhaps some logs, I should be able to determine what needs to be done.
Can you do this ? :
- Start the stock FM app, run for a few seconds, then stop it.
- Start my app, then send me logs with Menu->Help->EM Logs. In the email text please put "Galaxy Note" before pressing Send.
BTW, the stock S2/Note FM app seems pretty good, so I don't think you are missing too much from alternative apps at this time.
Also, I think my app may "work", more or less, if you start it while the stock app is running. I think the apps can co-exist simultaneously, but there are probably a few issues.
hello and thanks for your response.
You are right. The stock radio app is a lot better then the stock radio app on my windows mobile phone was. But still i dont like for example the really short textfield where the RDS text is written when the phone is in portait mode because most of the text is missing. It is better in landscape mode.
And of course alternatives are always good.
Your app works good when i keep the original radio app running in the background. (but i think the reception quality seems to be a bit worse with your app even on the same frequence. But i should test this more)
But it crashes as soon as i press the headphone/speaker button. Only a restart helps then to get rid of the stock radio-app and to get the radio working again.
i have send you a log file. hope it helps and keep up your work.

For Samsung Galaxy S, S2, Note, S3 etc:
Very experimental support for stock and stock derived ROMs with the Samsung Proprietary API. Works OK on my Galaxy S with Darky ROM Extreme Edition 10.2.
- Enable Settings->Debug->SA Proprietary.
- Restart the app.
http://www.mediafire.com/file/a12sm7m13smbjub/Spirit_FM_Radio_v120110.apk
- The Audio->Method is best set to the default of CyanogenMod, but might also work on Samsung, or even None or GalaxyS ALSA as a last resort.
Next release I'll re-enable the recording code and I think it will work on the Note, but might also work on Galaxy S/S2 devices.
If it works or not, please send me a log, best with SU/root:
Select Menu->Help-EM Logs, wait a few seconds, enter "Note" in the email text and press send.
I wish I could afford one of these Notes...

Another shot at Samsung Proprietary support for Galaxy S2 / Note class devices, in addition to Galaxy S devices w/ FM.
As before, enable Settings-Debug->SA Proprietary and restart. SU/Root should not be needed.
Regards,
Mike.
At least one person reports this working on a a Galaxy S2. Please let me know, positive or negative.
I could REALLY use some help testing my FM app on a Note or S2 with a stock or stock derived ROM on which the stock FM app works.
I can't afford one, US/Canada versions have no FM anyway, and Samsung's Remote Test Lab seems just about useless.
The Remote Note I tried started the Feb 26 Market version of my app in the Proprietary FM API mode OK, so I think it's close to working, but that API requires an earphone/antenna plugged in, and the test device doesn't have that. And I can't get the debug logs or shell access either.
There's a Feb 28 version linked here: http://forum.xda-developers.com/showpost.php?p=23059662&postcount=2357
For a few weeks now, my app works on my Galaxy S with stock derived Darky ROMs using the Samsung API, and un-rooted.
Thanks !

The first results are positive. I just listened to fm radio for about 15 minutes. It works through headphones and the speaker. But as far as I can tell the.reception seems to be somewhat worse than with the stock fm radio.
Phone is a N-7000 with stock ICS , rooted, PhilZ kernel. Are there any specific tests I should conduct?

Mikereidis's post has almost one year, looking at the Spirit FM thread OT, Galaxy Note is supported since (at least) november afaik.

ANT+ on the Nexus 5

Hello,
As It's difficult to search for "ANT+" in the forums, sorry if this issue has already been addressed
And now some extra keywords to ease the search: ant, ant+, antplus, ant_plus, antwireless, ant_wireless
This is a thread to summarized all the facts about ANT+ and the Nexus 5 I have found so far:
HARDWARE: BCM4339. The Nexus 5 has this chip which provides WiFi, BT and presumably ANT+. It's also present in the Galaxy Note 3 which reportedly has ANT+ capabilities.
DRIVER: The required driver source can be found here: https://github.com/ant-wireless . Once compiled it generates a module (libantradio.so) and two apk (AntHalService.apk, ANTRadioService.apk).
SOFTWARE: There are several apps with ANT+ enabled, but for testing purposes the ANT+ demo can be used.
To be able to test ANT+ I have the Nexus 5 and ANT+ capable hardware (HRM, cadence sensor, etc), the ANT+ Demo in google play but I'm missing the driver.
I know I need a kernel with module loading enabled (for example this modified stock: http://forum.xda-developers.com/showthread.php?t=2514765) but I don't know howto to compile the ANT+ module.
Can someone generate the driver as per the instructions in https://github.com/ant-wireless/ANT_in_Android or explain me how to do it?
I'm on a linux host, I have a rather limited experience in compiling stuff but I'm not afraid of learning something in the process!
Thanks!!
very interested in the results. thank you for your work on this
interested
Subscribed.
I am also interested in this as I have my phone and Garmin Forerunner watch with me when I run so if I can just carry my phone and get the same data that would be awesome!
If no one else takes this on, I'll see about looking into it later. Keep in mind though that I'm not a developer of any sort but am comfortable with compiling kernels. I have an ANT+ HRM from my Motoactv that I'd like to use.
Ok,
So far I haven't able to compile stock kernel. I'm trying with NDK GCC 4.7 without success: http://forum.xda-developers.com/showthread.php?p=47577117
But I've investigated in other fields. I've downloaded S4 and Note3 ROMS with ANT+ support to have a look at the files.
S4 CRASH_ROM_V11: http://forum.xda-developers.com/showthread.php?t=2322619
Note3 BoBCaTROM_V2.0: http://forum.xda-developers.com/showthread.php?t=2498687
This is want I've found so far:
There are three system apps: AntHalService.apk, ANTRadioService.apk and ANTPlusPlugins.apk. These two latter can be found in google play. The first app is the one that "informs" the system that the device is ANT+ capable (as stated in the ant_wireless git). I've tried to install this apk manually but fails due to certificates (samsung).
S4, Note3 and Nexus5 have all different revisions for the bcm433x firmware but they all have an "ANTLockUsed" string in it (hexdump). Is it related to ANT+ or the ANTenna? Incidentally, the wisol firmware revision doesn't have this string.
The rest of the files related to ANT+ are for the com.dsi.ant.antradio_library (etc/permissions and framework files).
I can't find any ANT+ related module (ant*.so, libant*.so). Thus, is it already compiled in the kernel or not needed at all?
I've uploaded all these files in case anyone wants to have at look them.
Subscribed. ANT+ support would be awesome for all the athletes out there.
I'm a big supporter of ANT+. I wish I knew more about Android to help on this side. I have a blog that documents a lot of hacking projects related to ANT+.
If the Nexus 5 could access ANT+ it could be an amazing cycle computer potentially.
I work a bit with a SOC from Nordic. The way it works for BLE is that it compiles and downloads a soft protocol. I'm wondering if this is how the Boardcom chip works too. My reasoning is in the github:
Additionally, in Android 4.2, the Bluetooth stack switched to Bluedroid (from BlueZ) and this existing ANT implementation for chips using Vendor Specific Bluetooth HCI messaging for ANT packets (wl12xx and bcm433x) is currently not compatible, until somebody is able to do the work for the different bluetooth stacks. The chip vendors may provide build support for their own products if you inquire with them.

So it sounds like, because ANT+ and BLE are so similar, they upload a new stack to the chip which enables it. However, this stack is not in the wild.

That makes sense as I wasn't able to find any more files related to ANT+ (directly not by looking into the source code).
However, I'm very stubborn and I want ANT+ in the nexus :silly:
First of all: It still doesn't work, but so far I've learnt a few things.
First I copied the Note3 files (attached) related to ANT+ (root needed, remember to chmod 644):
/system/app/AntHalService.apk (modified to strip samsung certificates)
/system/etc/permissions/com.dsi.ant.antradio_library.xml
/system/framework/com.dsi.ant.antradio_library.jar
/system/vendor/firmware/bcm4335_A0.hcd (renamed to bcm4335c0.hcd to max nexus5 firmware name. Backup old one first!!)
Upon reboot I also installed from google play the rest of ANT+ app required.
ANT radio service: https://play.google.com/store/apps/details?id=com.dsi.ant.service.socket
ANT+ Plugins: https://play.google.com/store/apps/details?id=com.dsi.ant.plugins.antplus
ANT+ Demo: https://play.google.com/store/apps/details?id=com.dsi.ant.antplusdemo
When using the ANT+ Demo App it doesn't warn about anything missing (good!!) but when searching for the HRM I have it just fails (bad!!). It fails with either firmware (nexus or note). In any case dmesg doesn't so any info related to ANT+.
To summarize:
The previous files are needed so that androids "knows" ANT+ hardware is present, but
Something else needs to be modified. As stated by kwakeham probably the bluetooth stack.
I have no android or coding skills (or any skills at all ), but with this information I hope someone can have a look at the modified bluetooth stack of either S4 or Note3 to port those changes to Nexus5 :fingers-crossed:
I'm very confident because XDA is a great place with lots of wonderful people, fully capable of implementing ANT+ in the Nexus5.
They've done much harder things!!
Is it true that Bluetooth 4.0 can only connect to one device at a time? So, if we wanted to monitor heart rate on the phone and listen to music via bluetooth headphones, this would not be possible unless we used an ANT+ heart rate monitor, correct?

Close but not quite.
A BT4 HR strap will only allow one device to connect to it at a time but the phone can connect to multiple BT devices at the same time. ANT+ lets an infinite number devices to connect to a single HR strap, so like your phone stashed in your pocket and a running watch on your arm. ANT+ would also allow you to read data from hundreds of sensors, though that would be more useful for a trainer at a spin class or something lol.
Exactly, and to verfy that I just connected two Bluetooth 4.0 devices with my Nexus 5. My Pebble and the fitbit Flex from my girlfriend, both worked fine simultaneously.
Btw, windows has a limit of 7 connected Bluetooth devices at a time, but that's not caused by the Bluetooth specification.

Hello,
Still no success.
I've been looking into the source code of both S4 and Note3 opensource kernels for android version 4.3, but due to lack of coding skills I just have no idea of what to search.
The source code of bluetooth stack from these kernels and the one for nexus5 seem completely different thus it's hard to draw any conclusions. The only thing clear is that running a "grep" search into the code for "ant+", "antplus", "ant_wireless" (or similar) doesn't show any results.
It seems someone is working on having ant+ on the google editon S4: http://forum.xda-developers.com/showthread.php?t=2542922
Let's hope his work can be reused for the nexus5.
PS. I don't have enough posts yet to ping him back to this thread but I will try to use the files he has attached.

That's me. I've found you looking for some info to help me out.
The main issue I'm facing is the AntHalService.apk from the vendors(Samsung,Sony) is the 3.0.0 and there were 2 updates already.
I compiled the 3.1.1 but I can't run it as a system app.
Regarding the Nexus 5, I guess that since S4 got ANT+ activated on 4.3, something in the updated radio probably activated it, and as you mentioned, no .so modules on the system.
Maybe analyzing the ANTHal code deeply might bring up some light on this.
Btw, you're Brazilian or Portuguese or Spanish? (due to your nickname)
If so, we can add each other on G+ and progress on talks to see if we can bring some light to the athlete droiders out there...
Worst case scenario you can use an USB Ant+ Stick with an OTG cable. (what I am going to do while I research for this.... )
Oh, btw, Galaxy S3 also had the hardware but Samsung never activated it...

With a bit of DIY you can make something smaller.
Thanks for the info! I'm going to look into it and probably buy it.
I'm also considering the Viiiiva, which acts as a bridge between all my Ant+ devices and Bluetooth 4. The bad thing is that there's no android app yet, in the mean time, the USB one will suffice.

Unfortunately I don't use G+ (or facebook or in fact any other so-called social network). I will try to be active here so we can achieve the desired ANT+ support.

Help finding rom and manufacturer for Android Car Multimedia

Hi Guys,
I have a car multimedia that came with my car, the brand is "Premier" - the problem is that it's a sticker brand, meaning this brand doesn't really exist.
The Multimedia is locked - I don't have GApps, I have a browser and ES File Explorer but I don't wanna flash anything since I don't really know which brand or which ROM I actually need.
This is the information under General >> About:
Processor Type: QuadCore-R16 16G
Android Version: 4.4.4
MCU Version: 5/3/19-11-10-453101-170320
System Version: 20170327_4.5.10
DVD Version: 2.13.15-860mc-160106
I have "Development tools" (not sure of the exact name, the one that you hit 7 times on the build number) but When I try to access it I'm being prompt for a password that I have no clue what it is.
No need to say that the importer of the system is not willing to provide the password.
I also like to mention that I have an issue when streaming music from my iPhone (Apple Music) to the Multimedia via Bluetooth.
I keep hearing a horrible distortion sound, Anyone encountered that and knows how to fix it?
Can you guys please advise?
If this is the wrong thread please point me to the correct one.
Hi,
So I wanted to give you a quick update, I talked to the company who imported this brand and I managed to get google play on it.
Since I'm not an android guy for a long time now, I wonder how can I stream music via AirPlay without the use of a wifi since I still don't have a dongle and the regular Bluetooth music streaming has a bad distortion. According to the support of this brand it happens on all of the Chinese multimedia android devices Due to songs in high bitrate. I tried to maybe airplay music from my iPhone to the android multimedia but couldn't find an app to work properly, anyone knows any airplay solution that doesn't need to be working when using wifi?

I'm not really sure how flashing goes. Maybe imaging 4.4.4 system.img being itself and mcu.img being vendor.img.. But that brings me back to my personal concern.. Does it need to be updated? Id suggest generic twrp

Android Auto with Android head unit

hey guys,
i just found out android head units exist and it makes me excited. that being said i have a subaru legacy 2015 and all ive wanted was the ease of use to have the address pulled up on my phone and have my head unit automagically have it and give be turn by turn directions on its screen. so i would like android auto because it seems to be the simplest to use and most intuitive because i use google music as my main source of music and google maps as my main maps. is this a option of the android headunits the reviews seem to focus on the android os not how it interacts with my phone, the last thing i want to do while driving is type in an address when someone text me i want to be able to hit a link and have it pop up on my headunit. you know what i mean?
anyways that's the main thing but i would like "ok google" being sent to my phone and displaying on the screen would be a big plus as well as backup cam support and dvr function and if magically possible retain control over my cars functions like changing my key locking functions would be nice but only if possible ive come to terms with losing that functionality.
car: subaru legacy limited 2015
phone: pixel xl

Fire tablet converted to Head Unit via flashing ROM - possible?

Hello all,
I have not found a thread/ROM about this, so I guess it is not possible. or is it?
It seems like it "should" be possible, but maybe the Head Units have some special hardware code that makes it impossible?
Thanks,
Mark.

Thanks, but I don't think I've made myself clear... there is a HUGE difference between installing the Android Auto app on a tablet and a built-in Android Auto device.
Everything I have seen by searching has been a tablet or phone with an app... The Android Auto app is going to be killed off very soon, and certain functionality will be developed only for the built in devices.
My question is whether a tablet can be hacked so GOOGLE sees your tablet as a built-in device, and will issue it with updates etc.

Even the chinese HU don't use android auto they have some other app that does the same and most people don't use it. In the end the concept of mirroring isn't that practical and there's too many hurdles such as apps have to be enabled for it...

So better to use a 3rd party app then I guess. Tx
