[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!

[Completed] Error when porting AOKP using source

Good evening to all. I have been trying to port AOKP for the HTC Desire 816 (htc_a5) for several weeks now, and I always get errors. The 816 already has 97% functional Cyanogenmod, So I'm using that as source. I repo synced with the Lollipop branch of AOKP and then used git clone to clone the CM device source ( https://github.com/CyanogenMod/android_device_htc_a5/tree/cm-12.0) into vendor/htc/a5. When I follow all the steps detailed in this guide, http://forum.xda-developers.com/showthread.php?t=2223690 I always get an error like this :
[email protected]:~/Working_dir$ . build/envsetup.sh
including vendor/aokp/vendorsetup.sh
including sdk/bash_completion/adb.bash
[email protected]:~/Working_dir$ lunch

Lunch menu... pick a combo:
\ 1. aokp_shamu-userdebug 4. aokp_grouper-userdebug 7. aokp_find7s-userdebug 10. aokp_sirius-userdebug

3. aokp_mako-userdebug 6. aokp_find7-userdebug 9. aokp_jfltevzw-userdebug 12. aokp_a5-userdebug
Which would you like? [aokp_shamu-userdebug] 12

** Don't have a product spec for: 'aokp_a5'

Any help would be VERY much apreciated! Thanks!

[Completed] Android M Source code Tagging

Okay, I'm trying to build Marshmallow preview 2 for the Nexus 7 2012, and I'm unsure of the source tagging on Google git.
I want to download the files using repo init, but obvious branch names aren't working.
I've tried this:
Code:
repo init -u https://android.googlesource.com/platform/manifest -b m-preview-1
But this returns a 404 error.
I think the manifest file is correct, but "m-preview-1" is a tag and not a branch name like last year's "l-preview" branch.
TL;DR
What is the repo init command to download the Nexus 7 2012 Android M preview 2 branch?
P.S
M preview 3 isn't on the git, which is why I'm doing preview 2.

Hello and thank you for using XDA Assist.
There is no XDA forum dealing specifically with building M Previews at this time, and I could only find the same external links you probably tried already. Even though it's not really device-specific, you may want to ask your question with all relevant details in the Nexus 7 Forum at http://forum.xda-developers.com/nexus-7 but I also see some related discussion in the Nexus5 area, such as http://forum.xda-developers.com/google-nexus-5/devs-only/android-m-source-t3122123 where the experts familiar with the Marshmallow build process might be able to guide you.
Good Luck!

Need help for ROM building

Hi there,
I'm trying to make a lineageos ROM for our great Xperia XZ but I face some problems.
I done all the steps of the ultimate ROM making thread on XDA, and i can't see my XZ in the device list of the lunch command.
To be precise i see it as aosp_f8331 and not lineage_f8331 nor lineage_kagura.
I already tried to build aosp on XZ without any success.
Maybe someone can light my candle.
Thanks

Looks like you haven't changed the "vendorsetup.sh" file
Should look like THIS (But where carbon is, put lineage)
You can also use "lunch lineage_kagura-userdebug"

THANKS,
Maybe this will help me a lot !
I was looking all over internet to find an answer and you gave it.

All good, XDA is a great place to learn, as long as the devs are friendly ?

If you need help, you can reach out to me

I figured out for the build issue,( thanks to @nzzane)
Now the kernel issue some files are missing so if anyone can help me,
I'll post a full tutorial from scratch and give ALL the needed files for building

[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

Can you tell me size of source code ?? How long it will take to download source code

Trying to build aosp O today. Still syncing

That is something! I'd like to test this build if you are successful.

Me too
Sent from my Moto G4 Plus using XDA-Developers Legacy app

Good step dude...
Just one request "Please focus to build Stable one rather then frequent unstable update"

I hope they do not abandon this project is very good
