Edge2 Download Android Source Code

Introduction

This document mainly introduces how to download the Android source code of Edge2.

Install git-lfs tool to download Android 12.0 SDK

$ sudo apt install git-lfs

1. Create an empty directory to hold your working files.

$ mkdir -p WORKING_DIRECTORY
$ cd WORKING_DIRECTORY

2. Run repo init to download the manifest repository first.

$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge2-android13

$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge2-android12

3. Run repo sync to pull down the Android source tree.

$ repo sync -c -j4

The initial sync operation may take an hour or more to complete.

You might need to run above command repeatly if it fails halfway. Or you can try with this script instead:

repo sync -c -j4
while [ $? = 1 ]; do
	echo "Sync failed, repeat again:"
	repo sync -c -j4
done

If needed, press Ctrl+C to quit.

4. Run the following command to pull large files. Otherwise, compilation will report an error.

$ repo forall -c 'git lfs pull'

5. Begin a new branch for development.

$ repo start <BRANCH_NAME> --all
