How to build (Ubuntu Server 26.04 LTS):

After setting up the Android build environment, do:

1. Install additional packages:

sudo apt-get install dosfstools e2fsprogs gdisk kpartx mtools rsync

2. Clone PawletOS-Build and install its dependencies:

git clone https://git.oxmc.me/PawletOS/PawletOS-Build
cd PawletOS-Build
pip3 install -r requirements.txt

3. Download the repo.yml config for this target:

curl -o repo.yml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/rpi/repo.yml

Or optionally, to reduce download size with a shallow clone:

curl -o repo.yml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/rpi/repo-shallow.yml

4. Run the build script (clones source and syncs it based on repo.yml):

python3 ./environ.py --applyPatches

5. source the environment:

. AOSP-Source/build/envsetup.sh

6. Select the device (rpi4 or rpi5) and build target (normal, tablet for tablet, tv for Android TV, or car for Android Automotive):

lunch pawlet_rpi4-bp4a-userdebug

lunch pawlet_rpi4_tablet-bp4a-userdebug

lunch pawlet_rpi4_tv-bp4a-userdebug

lunch pawlet_rpi4_car-bp4a-userdebug

lunch pawlet_rpi5-bp4a-userdebug

lunch pawlet_rpi5_tablet-bp4a-userdebug

lunch pawlet_rpi5_tv-bp4a-userdebug

lunch pawlet_rpi5_car-bp4a-userdebug

7. Compile:

make bootimage systemimage systemextimage vendorimage productimage -j$(nproc)

8. Make flashable image for the device (rpi4 or rpi5):

./rpi4-mkimg.sh

./rpi5-mkimg.sh
