Android 5.1 AOSP 源码获取

浏览数：26 / 时间：2015年06月11日

Android 5.1源码开放有一个多月啦，但由于城墙的关系，每次想着更新最新源码学习都万般纠结，现在发现国内有开源镜像啦，这就好多啦，感谢清华开源工作团队的无私工作啊。

地址：https://aosp.tuna.tsinghua.edu.cn/

根据页面上的介绍，该镜像只支持源码sync，不支持sdk更新。

AOSP 镜像服务单 IP 并发数限制为 4。因版权原因，我们无法提供 Android SDK 镜像。

可以看一下他给出的使用帮助：https://wiki.tuna.tsinghua.edu.cn/MirrorUsage/android

因为我本地已经安装好了repo工具，所以直接根据使用帮助里面介绍的repo init，然后repo sync就可以了。

下面介绍一下具体的步骤：

安装repo工具

repo需要安装最新版本的，如果已经像我一样之前有安装的，可以略过此步。

官方给出的repo下载如下：

curl https://storage.googleapis.com/git-repo-downloads/repo

但已经被X啦，国内搞不下来，可以从清华镜像clone下来，需要实现安装好git，如下：

git clone git://aosp.tuna.tsinghua.edu.cn/android/git-repo.git/

这样就会在当前目录下下载到git-repo目录里，将repo文件copy到~/bin/目录下，并修改可执行权限即可

repo init

新建存放源码的目录，我这里为 aosp目录，然后cd进入aosp目录，使用repo init目录来初始化仓库。

google官方给出的sync最新源码的命令为：

repo init -u https://android.googlesource.com/platform/manifest

如果不想获取到最新，只想得到某个指定版本，就需要多加一个-b参数，然后跟具体release版本名

repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1

可惜国内同样不能用啦，我们要做的就是把-u参数修改为TUNA（清华镜像）的，如下：

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

repo init -u git://aosp.tuna.tsinghua.edu.cn/android/platform/manifest -b android-5.1.0_r3

这里再扩展介绍一下 -b参数的获取，android版本号实在是太多啦，不仅andriod 4.0 5.0的，还有小版本r1 r2，怎么才能搞到正确的分支名呢，而且指定的分支名还需要你的更新源上得有的，通过下面的方式：

cd ~
git clone git://aosp.tuna.tsinghua.edu.cn/android/platform/manifest
cd manifest
git branch -a

这样就会列出aosp所有的分支名啦，从中找到你想要的即可

这样就开始更新代码啦，速度还不错。

替换已有的 AOSP 源代码的 remote

如果你之前已经通过某种途径获得了 AOSP 的源码(或者你只是 init 这一步完成后)，你希望以后通过 TUNA 同步 AOSP 部分的代码，只需要将 .repo/manifest.xml 把其中的 aosp 这个 remote 的 fetch 从 https://android.googlesource.com 改为 git://aosp.tuna.tsinghua.edu.cn/android/

<manifest>

   <remote  name="aosp"
-           fetch="https://android.googlesource.com"
+           fetch="git://aosp.tuna.tsinghua.edu.cn/android/"
            review="android-review.googlesource.com" />

   <remote  name="github"
