Android 5.1 AOSP 源碼獲取

本文已同步更新至：http://dxjia.cn/2015/08/android-aosp-code-sync/

Android 5.1源碼開放有一個多月啦，但因爲城牆的關係，每次想着更新最新源碼學習都萬般糾結，如今發現國內有開源鏡像啦，這就好多啦，感謝清華開源工做團隊的無私工做啊。

地址：http://mirrors.tuna.tsinghua.edu.cn/

根據頁面上的介紹，該鏡像只支持源碼sync，不支持sdk更新。

• AOSP 鏡像服務單 IP 併發數限制爲 4。因版權緣由，咱們沒法提供 Android SDK 鏡像。

能夠看一下他給出的使用幫助：http://mirrors.tuna.tsinghua.edu.cn/help/#AOSP

 

本文的步驟若是不成功，請移步上面的幫助連接，由於可能方法有變更。

 

由於我本地已經安裝好了repo工具，因此直接根據使用幫助裏面介紹的repo init，而後repo sync就能夠了。

 

下面介紹一下具體的步驟：

安裝repo工具

repo須要安裝最新版本的，若是已經像我同樣以前有安裝的，能夠略過此步。

官方給出的repo下載以下：

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

 

repo init

新建存放源碼的目錄，我這裏爲 aosp目錄，而後cd進入aosp目錄，使用repo init目錄來初始化倉庫。

google官方給出的sync最新源碼的命令爲：

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

若是不想獲取到最新，只想獲得某個指定版本，就須要多加一個-b參數，而後跟具體release版本名

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

惋惜國內一樣不能用啦，咱們要作的就是把-u參數修改成TUNA（清華鏡像）的，以下：

repo init -u https://aosp.tuna.tsinghua.edu.cn/aosp/platform/manifest
## 若是提示沒法鏈接到 gerrit.googlesource.com，能夠編輯 ~/bin/repo，把 REPO_URL 一行替換成下面的： ## REPO_URL = 'https://gerrit-google.tuna.tsinghua.edu.cn/git-repo'

android-5.1.0_r3repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b

這裏再擴展介紹一下 -b參數的獲取，android版本號實在是太多啦，不只andriod 4.0 5.0的，還有小版本r1  r2，怎麼才能搞到正確的分支名呢，並且指定的分支名還須要你的更新源上得有的，經過下面的方式：

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

這樣就會列出清華鏡像上aosp全部的分支名啦，從中找到你想要的便可

這樣就開始更新代碼啦，速度還不錯。

 

替換已有的 AOSP 源代碼的 remote

若是你以前已經經過某種途徑得到了 AOSP 的源碼(或者你只是 init 這一步完成後)， 你但願之後經過 TUNA 同步 AOSP 部分的代碼，只須要將 .repo/manifest.xml 把其中的 aosp 這個 remote 的 fetch 從 https://android.googlesource.com 改成 https://aosp.tuna.tsinghua.edu.cn/

 

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