Android Source Code branch of Khadas VIMs is located on GitHub, and there are many different branches here. You can follow the steps to download the Source Code.

Install git-lfs tool to download Android 11.0 SDK

$ mkdir git_lfs
$ cd git_lfs
$ wget https://github.com/git-lfs/git-lfs/releases/download/v2.3.4/git-lfs-linux-amd64-2.3.4.tar.gz
$ tar xvzf git-lfs-linux-amd64-2.3.4.tar.gz
$ cd git-lfs-2.3.4
$ sudo ./install.sh
$ git lfs install

1) Create an empty directory to store 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-vim4-r

3) Run repo sync to pull down the Android Source branch:

$ repo sync -j4

It will take approx one hour to complete the initial sync operation.

#!/bin/bash
repo sync -j4
while [ $? = 1 ]; do
echo "Sync failed, repeat again:"
repo sync -j4
done

4) Begin a new branch for development:

$ repo start <BRANCH_NAME> --all
