[Q] Need help on building android from source

Hello, I just found out I posted this in the wrong forum section before :crying: sorry!
I can't post links because I'm new here, so I'll tell you how to find the links to what tutorial/website I'm using.
If you just search "building android from source", at the fifth link from the top, it should say "Getting Started: Building Android From Source" (xda-university). If you go there and scroll down to "Initialising repo and syncing", that's where I'm stuck at. To just add some info, I'm doing this to start off building cyanogenmod at a later time for my device; as, it isn't supported.
But anyway, where it says to run "repo init -u < URL to android manifest > -b < branch name > " [I replaced the &gt and &lt's]
I'm not sure what url/branch to put. My device isn't supported by cyanogenmod and I dont know where my device repo's are in general (and if there are any at all).
It's a Samsung Galaxy Admire 4G (SCH-R820).
Any help is appreciated, thanks!

Lollipop Source - Official Nvidia Repository

The developer site is still listing KitKat as the newest build, so here are the links to the instructions to build Lollipop using the official source:
Lollipop 5.0: http://nv-tegra.nvidia.com/gitweb/?...a=blob_plain;f=README;hb=rel-st8-l-r1-partner
Lollipop 5.0.1: http://nv-tegra.nvidia.com/gitweb/?...a=blob_plain;f=README;hb=rel-st8-l-r2-partner

Cheers mate. It is still listing the 1.2.1 OTA as the latest but just by changing the branch url i was able to find the newest.
Lets hope for some more development on this device. I'm going to PM you soon - I will be building my own ROM and/or Kernel.

You do realize those are the links posted above. There is no need to switch branch names or search for the current files. Just click the one you want.

Of course, mate!
I was saying that I found the proper page by changing the URL to hb=rel-st8-l-r2-partner, before this thread was posted. So I appreciate you enlightening other folks about it!

Even without already having the branch name, it's just a matter of going to http://nv-tegra.nvidia.com/gitweb/?p=manifest/android/binary.git;a=summary to find it

Hi, @twistedumbrella could you please spare a second to help (or point me in the right direction) I've successfully built Lollipop for my Oneplus One using Ubuntu, but when I try to set up first repo sync; well see below:
When I run: repo init -u git://nv-tegra.nvidia.com/manifest/android/binary.git -b rel-st8-l-r2-partner -m tlk/shieldtablet.xml
I get: fatal: manifest 'tlk/shieldtablet.xml' not available
fatal: remote github not defined in /home/diigimatrix/.repo/manifests/tlk/shieldtablet.xml
Please could you get me on my way. I love all your work and hope to gain further knowledge through your support.
Thanks in advance

I'm trying to figure out what's up with it now. I know when I synced it was r1, and tlk/shieldtablet.xml was valid.
Hopefully I can track down why it is coming back invalid in r2.

Thanks @twistedumbrella, glad in a way its not just me. Thought I was running the wrong command. . Happy New Year!

Same to you. It updated ok but now I have to see if it'll re-init. It may be a delay on their end. The readme for the portable was up a week before the source.

Cool. I'll give it another try once I've finished work. Been a member for years and helped a lot in the old windows phone days. But thought enough of just relying on other people, time to start getting my hands dirty again. But new to building Android. Need to read up on manipulation of ROMs rather than just building a stock ROM. Any tips on tools to manipulate ROMs? Am i right by merging commits then build, then manipulate ROM? I will read up on it but just thought you might have some pointers. Thanks

Best bet is to either find something you like and merge it or try to find something similar and recreate it to start. Once you get comfortable, then start coming up with your own.
Building from source is mostly Java for modifying with some C for drivers and such. Usually when you have a device configuration already set up, though, the C part is already done.

Just wanna say a big thanks to @twistedumbrella. I set up a new ubuntu build environment and I'm now compiling my first Android build for Nvidia Shield Tablet EU-LTE. No mods yet other than stock, but hopefully with time.

Hi! I'm trying to compile but get error trying no find:
./packages/apps/UnifiedEmail/src
After repo sync, I don't have "src" directory for this package.
Thnx in advance.

It looks like they are still working out a few issues with new updates. I don't maintain the source, so the only advice I can provide is to keep on eye on nvidia's gitweb for when they publish a solution (or occasionally sync and try over), or attempt to fix it yourself (which usually only works if there is an issue with the code, not code missing altogether).

Compiled! I have resynchronized all the project from scratch from git repository.
I'm going to test the compiled ROM in my tablet, but I suppose, I have to provide almost the essential pack of Google apps (basic providers and play services).
I think to flash *.img files, except recovery.img (I'm on TWRP), and then install from TWRP PA Gapps. Is this approach correct?
Thnx in advance and regards.
EDIT: No luck booting custom rom (TWRP nor stock recovery...)

Seem's like there's a new source three version out:
repo init -u git://nv-tegra.nvidia.com/manifest/android/binary.git -b rel-st8-l-r3-partner -m tlk/shieldtablet.xml

Where to start to build a new custom ROM?

Hi. I've always been curious to try to build a new aosp based ROM.
I know java but I don't know CPP... Only a bit. Anybody thinks I could start something? Even in a team, of course. Where to start?

First of all, it depends on how much you already know.
There are numerous guides on how to build another existing custom ROM. I'd start with those first to be a little familiar with how a project is handled, but you could always just look for guides for building one from scratch AOSP if you wanted to.
There are plenty of guides on the internet, and if you run into an issue, someone else has likely already asked about it and received an answer.

^^^^^^^^^^^^^

I'd also be interested in learning how to manage/develop a custom rom. Let's get Team n00b started up

I´m bumping this topic though the last answer is over one month ago
Creating, managing a Custom ROM of any kind is very time consuming and some people will always expect you to release updates as fast as possible and to work for free Even if you´ve set up your developing environment ( I use Linux ), you will need a lot of patience and a hell of a PC to compile stuff without waiting too long.
If I were you I would think twice if I want to a) build a ROM for yourself only or b) also go through the pain of maintaining a thread, webspace and online support.
The Nexus forums are crowded with AOSP based ROMs and I don´t think that one thread more or less would matter. What I build for myself simply needs to be reliable without 1000x different Mods or Themes.
Since I barely have any time for this hobby anymore, I stick to a) only and even by doing so, I will also waste a lot of time since sometimes there are unforeseen consequences

Yes. That's what I ended too. It would take too much time and resources. I just stopped thinking about that (because my linux pc is very old, too) and used a good ROM.
Thanks!

Quick question
I'm trying to build M developer preview from AOSP. I'm currently syncing the repo with the command:
Code:
repo init -u https://android.googlesource.com/platform/manifest.git -b android-m-preview
After this is synced I will add my device to the appropriate folder with the code:
Code:
git clone https://android.googlesource.com/device/lge/hammerhead.git -b android-m-preview hammerhead
After this will I be able to compile and build?
Am I on the right track?

Correct me if I'm wrong, but you can just add the device specific code on the manifest (by modifying .repo/manifest/default.xml)

I didn't add my device on the manifest. I followed another guide specifically for my phone and AOSP.
Now, I'm stuck at this:
Code:
Header: out/target/product/hammerhead/obj/include/gps.utils//loc_log.h
make: *** No rule to make target `hardware/qcom/gps/utils/log_util.h', needed by `out/target/product/hammerhead/obj/include/gps.utils//log_util.h'. Stop.
make: *** Waiting for unfinished jobs....
Header: out/target/product/hammerhead/obj/include/gps.utils//loc_cfg.h
I used the Preview binaries from Google.
Does this mean the latest blobs do not compile for M?
Edit: Found my answer here

[Completed] Trying to Build CM 12.1 for Galaxy Avant but Unable to Figure Out How to Lunch Device

Hi, I am trying to build CyanogenMod for the Samsung Galaxy Avant (for learning purposes), but it not supported by the ROM. This is my first build ever, so please cut me some slack. I have been following a tutorial to build one for this phone, and was successfully able to get to the "lunch" stage of the build. When I "lunch" the device name, however, I receive an error in Terminal:
build/core/product_config.mk:234: *** Can not locate config makefile for product "afyonltetmo". Stop.
Device afyonltetmo not found. Attempting to retrieve device repository from CyanogenMod Github (ht tp:// github . c om/ Cyanogen Mod).
Repository for afyonltetmo not found in the CyanogenMod Github repository list. If this is in error, you may need to manually add it to your local_manifests/roomservice.xml.
build/core/product_config.mk:234: *** Can not locate config makefile for product "afyonltetmo". Stop.
** Don't have a product spec for: 'afyonltetmo'
** Do you have the right repo manifest?
This prevents me from continuing with the build, so what do I do to fix it? How do I manually add it to my local_manifests? I am doing this on Ubuntu 14.04 64 bit, by the way. Also, I can use the stock kernel to for this build right? The current ROM I am running does not support wifi or using the camera. Sorry for this noobish question, and thanks for all of your help.

[DEV][HELP]Custom ROM development[Possibly Oreo]

Hello Moto G community!
I am a newbie to Android development but I have a will to learn and work hard. I would like to obtain help from developers while I embark on a mission to build a Android ROM for our beloved Moto G falcon.
What I already did:
1. Setup AOSP build environment from Android official tutorial and had a successful build of nougat 7.1.1
2. Currently, I have setup the build environment for lineage-os using this guide:
https://forum.xda-developers.com/chef-central/android/how-to-build-lineageos-14-1-t3551484
A Lineage 14.1 build is in progress as I write this and hopefully there will be no errors. I plan to flash it on my device and try it out personally to see for myself how well it turns out to be. *Done
Plan:
1. I wish to build an Android 8.x ROM eventually. Lineage is not ready yet, so I was thinking of going ahead with AOSP. Correct me if I am wrong.
2. If I do that, I will first have to build the falcon device tree. I will follow some tutorials for that but will need help here.
3. When I am done with that, I will start the building process and that is when the real work starts.
I will start building the device tree in 2-3 days and will post for help wherever required. I will keep this thread updated with my progress and resources as well.
Anybody who is willing to work with me on this project is welcome to do so. Send me a PM and we can be a team.
To moderators:
1. This is my first time creating a thread on XDA Forums. If I made a mistake, please let me know.
2. This is not just another Android Oreo thread. I plan to learn Android device development and coincidentally the time matches with Android O release. Possibly a good time to learn
My Devices:
Moto G (falcon) XT1033 India
Moto G4 Plus (athene) XT1644 US

this is great, good luck bro, i am waiting for android O :laugh::fingers-crossed:

Here comes the first one:

Couldn't find a solution to this not-so-rare problem.

I just re-ran
Code:
brunch falcon
and did not see that error again. It is not reproducible.
Now I am stuck at Out of Memory error for the same file. I tried reducing max-services for jack server in config file to 1.
I tried multiple heap sizes (2,4,6,8 GB) using -Xmx flag. No luck.
I am curious as to why AOSP built successfully and LOS is showing these errors. They both use jack-server right?
I will search for a solution for a few hours now. If anyone has any, please let me know.
Edit: Alright! I made a build without using ninja.
Code:
export USE_NINJA=false
brunch falcon
Took longer, but succeeded. It boots but SetupWizard stops after setting up Google account. Cannot bypass it to home. Deleting LineageSetupWizard in /system/priv-app using adb works.
See screenshot below.
This completes 1 task. I can start building the device tree tomorrow.

great still like this
