Device specific configuration to build AOSP Android 14 for Raspberry Pi 4 and Raspberry Pi 5.

---

How to build:

1. Establish Android build environment and install repo.

2. Install additional packages:

sudo apt-get install bc coreutils dosfstools e2fsprogs fdisk kpartx mtools ninja-build pkg-config python3-pip
sudo pip3 install meson mako jinja2 ply pyyaml dataclasses

3. Initialize repo:

repo init -u https://android.googlesource.com/platform/manifest -b android-14.0.0_r30
curl -o .repo/local_manifests/manifest_brcm_rpi.xml -L https://raw.githubusercontent.com/raspberry-vanilla/android_local_manifest/android-14.0/manifest_brcm_rpi.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-14.0.0_r30 --depth=1
curl -o .repo/local_manifests/manifest_brcm_rpi.xml -L https://raw.githubusercontent.com/raspberry-vanilla/android_local_manifest/android-14.0/manifest_brcm_rpi.xml --create-dirs
curl -o .repo/local_manifests/remove_projects.xml -L https://raw.githubusercontent.com/raspberry-vanilla/android_local_manifest/android-14.0/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 aosp_rpi4-ap1a-userdebug

lunch aosp_rpi4_tv-ap1a-userdebug

lunch aosp_rpi4_car-ap1a-userdebug

lunch aosp_rpi5-ap1a-userdebug

lunch aosp_rpi5_tv-ap1a-userdebug

lunch aosp_rpi5_car-ap1a-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

Also look into Linux kernel build instructions.
