====== Edge-2L Download Android Source Code ======

===== Introduction =====

This document mainly introduces how to download the Android source code of Edge-2L.

===== Download from github =====

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.

<tabbox Android 14>
```shell
$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-edge-2l-android14
```

</tabbox>

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

```shell
$ repo sync
```
<WRAP important> 
Do **NOT** add the `-j` option when running `repo sync`. The manifest file for this project includes a remote configuration for `gitkhadas` (https://git.khadas.com/) with `sync-j="1"`. Using `-j` with a higher concurrency value will override this restriction and likely cause sync failures. 
</WRAP>

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

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

</WRAP>

4. Begin a new branch for development.

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