TUNA的AOSP使用帮助：
https://mirrors.tuna.tsinghua.edu.cn/help/AOSP/
安装GIT(Ubuntu)
sudo apt-get install git
源码下载
下载 repo 工具:
mkdir ~/binPATH=~/bin:$PATHcurl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repochmod a+x ~/bin/repo
建立工作目录:
mkdir WORKING_DIRECTORYcd WORKING_DIRECTORY
初始化仓库:
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest
或 repo init -u git://aosp.tuna.tsinghua.edu.cn/aosp/platform/manifest
如果提示无法连接到 gerrit.googlesource.com，可以编辑 ~/bin/repo，把 REPO_URL 一行替换成下面的：
REPO_URL = ‘https://gerrit-google.tuna.tsinghua.edu.cn/git-repo’
如果需要某个特定的 Android 版本(以android-4.0.1_r1为例):
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-4.0.1_r1

接下来就是漫长的等待……
在校园网中下载速度会比较快
下载Android5.0源码压缩成.tar.gz后有26GB，可以参考一下
