How to build (Ubuntu 22.04 LTS):

1. Establish Android build environment.

2. Install additional packages:

sudo apt-get install dosfstools e2fsprogs fdisk kpartx mtools rsync

3. Initialize repo:

repo init -u https://android.googlesource.com/platform/manifest -b android-16.0.0_r1
curl -o .repo/local_manifests/manifest_brcm_rpi.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/vendors/brcm_rpi.xml --create-dirs
curl -o .repo/local_manifests/manifest_lineageos.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/vendors/lineageos.xml --create-dirs
curl -o .repo/local_manifests/manifest_pawletos.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/pawletos.xml --create-dirs

Or optionally, you can reduce download size by creating a shallow clone and removing unneeded projects:

repo init -u https://android.googlesource.com/platform/manifest -b android-16.0.0_r1 --depth=1
curl -o .repo/local_manifests/manifest_brcm_rpi.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/vendors/brcm_rpi.xml --create-dirs
curl -o .repo/local_manifests/manifest_lineageos.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/vendors/lineageos.xml --create-dirs
curl -o .repo/local_manifests/manifest_pawletos.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/pawletos.xml --create-dirs
curl -o .repo/local_manifests/remove_projects.xml -L https://git.oxmc.me/PawletOS/android_local_manifest/raw/branch/android-16.0/remove_projects.xml

4. Sync source code:

repo sync

5. Setup Android build environment:

. build/envsetup.sh

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

lunch pawlet_rpi4-bp2a-userdebug

lunch pawlet_rpi4_tv-bp2a-userdebug

lunch pawlet_rpi4_car-bp2a-userdebug

lunch pawlet_rpi5-bp2a-userdebug

lunch pawlet_rpi5_tv-bp2a-userdebug

lunch pawlet_rpi5_car-bp2a-userdebug

7. Compile:

make bootimage systemimage vendorimage -j$(nproc)

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

./rpi4-mkimg.sh

./rpi5-mkimg.sh
