Build your own android-28 sources

android-28-sources.md

Build "Sources for Android 28" so you can comfortably browse the Android API source in Android Studio.

1. Collect source files

mkdir android-sdk-source-build
cd android-sdk-source-build

mkdir -p frameworks/base

# Fetch repositories that contain the sources we're interested in
git clone --depth 1 https://android.googlesource.com/platform/frameworks/base -b android-9.0.0_r3 frameworks/base
git clone --depth 1 https://android.googlesource.com/platform/libcore -b android-9.0.0_r3
git clone --depth 1 https://android.googlesource.com/platform/development -b android-9.0.0_r3

# Create a basic source.properties file
echo -e "Pkg.UserSrc=false\nPkg.Revision=1\nAndroidVersion.ApiLevel=28" > source.properties

# Modify the script to create a sources ZIP to use "android-28" as top-level directory
cat development/build/tools/mk_sources_zip.py | sed -e 's/TOP_FOLDER = .*/TOP_FOLDER = "android-28"/' > my_mk_sources_zip.py

# Run the script to create android-28-sources.zip
python my_mk_sources_zip.py -z source.properties android-28-sources.zip .

2. Extract into Android SDK source directory

unzip android-28-sources.zip -d ${ANDROID_HOME}/sources

3. Restart Android Studio and SDK sources should show up.

Or just download the ZIP: https://hugo.cketti.eu/android-28-sources.zip (32 MB)

I like the lazy approach 👍 thanks @cketti!

Anyone got android sdk 29 source code?

@MIkeeJY

Replace android-9.0.0_r3 branches with android10-release branches.

# Create a basic source.properties file
echo -e "Pkg.UserSrc=false\nPkg.Revision=0\nAndroidVersion.ApiLevel=29" > source.properties

I used Pkg.Revision=0 so SDK manager can update to official revision 1 when it comes out.

Replace android-28 in the last two commands with android-29.

python my_mk_sources_zip.py source.properties android-29-sources.zip .

I dropped the -z option because I run in Windows and there's no "zip system exec". You'll need Python 2.7 to run the script.

The rest is the same.

I have automated this script using Github Workflow here: https://github.com/ni554n/sources-for-android-sdk

You can download the package and watch for Releases to get notified of the upcoming API source builds.
