====== Edge1 Download Android Source Code ======

===== Introduction =====

This document mainly introduces how to download the Android source code of Edge1.

===== Get Source Code =====

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

```shell
$ mkdir -p WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
```

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

  * Android 10.0: ```shell
$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge-Qt
```
  * Android 9.0: ```shell
$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge-pie
```
  * Android 7.1: ```shell
$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge-nougat
```

3. Run ''repo sync'' to pull down the Android Source Tree:

```shell
$ repo sync -c -j4
```

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

<WRAP info >
You might need to run above command repeatly if it fails halfway. Or you can try with this script instead:
```bash sync_helper.sh
#!/bin/bash
repo sync -c -j4
while [ $? = 1 ]; do
	echo "Sync failed, repeat again:"
	repo sync -c -j4
done
```

If needed, press ''Ctrl''+''C'' to quit.

</WRAP>

4. Begin a new branch for development:

```shell
$ repo start <BRANCH_NAME> --all
```
