This document mainly introduces how to download the Android source code of VIM4.

Install git-lfs tool to download Android 11.0 SDK

$ sudo apt install git-lfs

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-64bit

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. Go to the following directory and execute the git lfs pull command to pull large files. Otherwise, compilation will report an error.
