how can I verify that it is picking the android sources from this respective branch

[Appu]

Dear Android Building experts,

Could you please let me know, I am trying to build the android source code from respective branch for ex: android-9.0.0_r45, how can I verify that it is picking the android sources from this respective branch - android-9.0.0_r45? once after it is downloaded or after it is built?

Steps to reproduce:

1. https://source.android.com/setup/build/downloading

Used branch “android-9.0.0_r45”

repo init -u https://android.googlesource.com/platform/manifest -b android-9.0.0_r45

2. Setup for build – This step has to be done only once

<repo dir> $ source env_setup.sh

<repo dir> $ lunch

Choose “aosp_x86_64-eng”

Many Thanks in advance,

[David]

Hey Appu,

not an expert but on the source code go to the repo manifest branch `cd <repo dir>/.repo/manifests`.

With `git show` you can see the latest commit and also the attached tags.

(The manifests folder describes which repository version repo syncs.) 

https://gerrit.googlesource.com/git-repo/+/refs/heads/master/docs/manifest-format.md

With `repo status` you can see your local changes.

https://source.android.com/setup/develop/repo#status

On the device you can get some build information with:

`adb shell getprop | grep ro.build`

But as far as I know you can't get the branch used for the build.

I hope that helps.

Cheers,

David

Thanks a lot David! Really appreciate the same.

Is there anyways that can I figure out, roughly around which dates  approx- android's repo , branch, tags & the specific commit ID - the below patch was applied and tried?

https://android-review.googlesource.com/c/platform/system/core/+/633925  

based on the above patch, I see the parent commit ID is  "https://android.googlesource.com/platform/system/core/+/d555e08224d2a08f4f12c16ae4109b63b9f7def9",  but could you please let me know , is there anyways that can I figure out the specific android's repo , branch, tags & the specific commit ID 

As I am trying to bringup new usb host controller ip for android debugging, that requires some custom changes on adbd,

I guess the andorid version that is being used is “android-9.0.0_r45” (but I don't know the specific branch or commit id to get the same commit id), but when I try to build this version and replace the adbd in system.raw.img, I am unable to launch the settings icon, as it tries to keep loading but it doesn't launch at all.

https://source.android.com/setup/build/downloading & the below is the build procedure (please correct me if the below procedure is wrong for building android)

2. Setup for build – This step has to be done only once

<repo dir> $ source env_setup.sh

<repo dir> $ lunch

Choose “aosp_x86_64-eng”

As I tried using the command "adb shell getprop | grep ro.build" it didn't help on the target, to get the specific android repo with specific branch tags & commit id.

Could you please provide any inputs or pointers on the above please, I tried googling randomly for 2-3 days, I didn't get any clues on it.?

Many Thanks in advance
