Building

You'll need to get familiar with Git and Repo as well as How to build a GSI.

Create Directories

As a first step, you'll have to create and enter a folder with the appropriate name. To do that, run these commands:

mkdir YAAP
cd YAAP

Initalise the Treble YAAP repo

repo init -u https://github.com/yaap/manifest.git -b fourteen

Clone the Manifest

This adds necessary dependencies for the YAAP GSI.

git clone https://github.com/ahnet-69/treble_manifest.git -b yaap-14 .repo/local_manifests

Sync the repository

repo sync --force-sync --optimized-fetch --no-tags --current-branch --no-clone-bundle --prune -j$(nproc --all)

Apply the patches

Copy the patches folder to the ROM folder, and run this in the ROM folder:

patches/apply-patches.sh .

NOTE: It is recommended to apply patches manually by going to the respective directory of the patches, and applying them by using `git am`, as the script often skips applying critical patches for some reason.

Adapting for YAAP

Clone this repository and then copy YAAP.mk to device/phh/treble in the ROM folder. Then run the following commands:

 cd device/phh/treble
 bash generate.sh YAAP

Turn On Caching

You can speed up subsequent builds by adding these lines to your ~/.bashrc OR ~/.zshrc file:

export USE_CCACHE=1
export CCACHE_COMPRESS=1
export CCACHE_MAXSIZE=50G # 50 GB

Reduce File Sizes

BOARD_EXT4_SHARE_DUP_BLOCKS := true

This flag makes the blocks shared, and makes the build read-only. It ensures it fits on to all possible Treble-supported devices, since many devices have a small system partitions.

Compilation

In the ROM folder, run this for building GAPPS:

. build/envsetup.sh
ccache -M 50G -F 0
lunch treble_arm64_bgN-userdebug 

 # Remove TARGET_BUILD_GAPPS=true if building vanilla.
TARGET_BUILD_GAPPS=true make systemimage -j$(nproc --all)

Compression

After compiling the GSI, you can run this to reduce the system.img file size:

Warning
You will need to decompress the output file to flash the system.img. In other words, you cannot flash this file directly.

cd out/target/product/tdgsi_arm64_ab
xz -9 -T0 -v -z system.img

Troubleshooting

If you face any conflicts while applying patches, apply the patch manually. For any other issues, report them via the Issues tab.
