在国内下载Android AOSP代码的方法

xusheng

文档描述的下载步骤：

1. 从谷歌官网下载kernel5.10开源组件包

1. git clone -b android12-5.10 https://android.googlesource.com/kernel/common linux-5.10.y

复制代码

2. 从谷歌官网下载aosp开源组件包

1. repo init -u https://android.googlesource.com/platform/manifest -b android-12.0.0_r2
   
2. repo sync

复制代码

问题：
在国内如没有VPN，是无法从谷歌官网下载上述代码包的

解决方案：
使用清华镜像服务器，将https://android.googlesource.com 替换为：https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/

流程：
1. 下载kernel

1. git clone -b android12-5.10 https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/kernel/common linux-5.10.y
   

复制代码

2. 下载repo工具本体

1. mkdir ~/bin
   
2. PATH=~/bin:$PATH
   
3. curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
   
4. chmod a+x ~/bin/repo

复制代码

3. 克隆Manifest仓库

1. ~/bin/repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-12.0.0_r2

复制代码

问题1：在下载repo工具代码时出现异常

Downloading Repo source from https://gerrit.googlesource.com/git-repo
“无法连接服务器”

解决：指定国内git-repo仓库地址

1. ~/bin/repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-12.0.0_r2 --repo-url=https://mirrors.tuna.tsinghua.edu.cn/git/git-repo

复制代码

问题2：出现警告提醒

repo: error: Your version of "git" (1.9.1.1.9.1) is no longer supported; Please upgrade to at least version 2.7.4 to continue.
repo: warning: git-2.7.4+ will soon be required; please upgrade your version of git to maintain support.

解决：升级git版本

1. sudo add-apt-repository ppa:git-core/ppa
   
2. sudo apt update
   
3. sudo apt install git

复制代码

本步骤完成后，会在当前目录下创建 .repo 目录，并包含下述内容：

• manifests/      该子目录下存放了克隆的Manifest仓库文件
• manifest.xml   指向当前使用的XML配置文件
• repo/              存放了完整的Repo工具代码
  

4. 同步AOSP代码

1. ~/bin/repo sync

复制代码

执行该命令、会根据清单文件同步所有子仓库的代码。同步的信息摘录如下：
