前言
开源镜像站是一个放置开源系统镜像文件的站点,免费提供镜像文件下载。
谷歌被墙,在下载安卓源码和SDK时,各种没有进度。这时,就要感谢国内镜像站了。

研究Android尤其是Android系统核心或者是驱动的开发,首先需要做的就是克隆建立本地Android Source版本库。
Branches in Git are incredibly lightweight as well. They are simply pointers to a specific commit – nothing more. This is why many Git enthusiasts chant the mantra:
branch early, and branch often.
Because there is no storage / memory overhead with making many branches, it’s easier to logically divide up your work than have big beefy branches.
When we start mixing branches and commits, we will see how these two features combine. For now though, just remember that a branch essentially says “I want to include the work of this commit and all parent commits.”
