[AIOT] How to Build Tinker Board 2 Android OS Image

1. Establish a build environment
Please refer to Install Docker Engine to install Docker engine.

2. Download the Android source

3. Initiale a Repo client
Run repo init to get the latest version of Repo with its most recent bug fixes. You must specify a URL for the manifest, which specifies where the various repositories included in the Android source are placed within your working directory. For different projects, you must also specify the manifest branch or revision with option "-b REVISION".

repo init -u https://github.com/TinkerBoard-Android/rockchip-android-manifest.git -b REVISION
 

Optionally, you can also specify the initial manifest file with the option "-m NAME.xml" for the specific release for that project.

repo init -u https://github.com/TinkerBoard-Android/rockchip-android-manifest.git -b REVISION -m NAME.xml

To download the Android source tree to your working directory from the repositories as specified in the default manifest, run:

repo sync
 

5. Build Android
Go to to the directory where you have downloaded the Android source and execute the script as the following. This will take a while to install the necessary packages on the host, build the Docker image, and start the container:

./docker_builder/docker-builder-run.sh
 

Once it is done. You are in the shell of this newly started Docker container and you are ready to build Android.
