国内镜像下载android源码

转载自：国内镜像加速android源码下载

1.下载修改好的repo，====下载地址====，密码：rb5t；

2.打开终端，输入：

12	mkdir ~/binPATH=~/bin:$PATH

3.将repo放入~/bin目录下；

4.赋予执行权限，终端输入：

chmod a+x ~/bin/repo

5.建立android源码存放目录：

1	mkdir android_source cd android_source

6.查看想要下载的源码的Tag和Builds，网址： ====点击查看，需要翻蔷====

7.例如我要下载android-5.1.1_r3，就在终端输入：

1	repo init -u git://aosp.tuna.tsinghua.edu.cn/android/platform/manifest -b android-5.1.1_r3

8.终端输入下面命令使用repo开始源代码下载同步，-j4表示并发数为4，清华镜像只支持最大并发数4：

1	repo sync -j4

9.漫长的等待后，源码下载完毕。速度在200～800KB/s不等。

附加repo源码：
