ubuntu下android源代码以及内核的获取

android源码的获取

1.安装git，curl

sudo apt-get install git

sudo apt-get install curl

2.新建一个目录android,在这个目录下建立bin,kernel,source三个子目录。bin用来存放repo，kernel用来存放android内核源代码，source目录用来存放android源代码。

3.输入

$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

添加环境变量

PATH=/root/android/bin:$PATH

$ chmod a+x /root/android/bin/repo

4.切换到source目录，输入

$ repo init -u https://android.googlesource.com/platform/manifest
如果是获取一个分支的源代码则输入

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

-----------------------------------------------------------

可用的分支(部分)

* [new branch] android-cts-4.0_r1 -> origin/android-cts-4.0_r1

-----------------------------------------------------------

-b后面为分支的版本

5.输入 $ repo sync

在这个过程中要输入用户名和邮箱，随便输入一下就好了

android kernel的获取

1.切换到kernel目录，输入

$ git clone http://Android.git.kernel.org/kernel/common.git
2.下载完后，什么都看不到，这是切换到kernel下的common目录，输入

$ git branch -a

查看内核版本分支

* master

remotes/origin/HEAD -> origin/master

remotes/origin/android-2.6.39

remotes/origin/android-3.0

remotes/origin/master

3.输入

$ git checkout remotes/origin/android-3.0获取分支

其他有用命令

将origin这个版本库的代码更新到本地的master主枝：

$ git pull origin master

将本地的代码更新到名为orgin的远程版本库中：

$ git push origin
