Want to extract the Android source code. You'll have to use Git. The following is a problem with the installation process: 1.1 Install git. Win's command-line client (quite as used by the SVN turtle). http://git-scm.com/download/win1.2. Or you can use Eclipse's git plugin. But this article is using Git-1.8.0-preview. 1.3 The installation process is always the next step. 2. After installing Git. Just find a folder ready to drag someone else's source on the Internet. 2.1 Enter that folder. The first step is to initialize your folder. Right---"Git Init here" (or if your computer is more bull B, it's changed to Chinese.) I can't do it.) 2.2 If you have initialized that folder. You'll never see the git Init here 2.3 and then right-click on the Git GUI tool and Git Bash. Some people like to use the Git GUI tool inside. But I don't really use it. Or just use "Git Bash" 3. Yes. You see those command lines. Don't you be afraid. Basically those commands don't have to knock on their own. Usually you can find the source address you want to provide. For example: The almighty github:https://github.com/google some Open source code: androidhttps://android.googlesource.com/?format=html3.1 I will extract the Android alarm clock source For example https://android.googlesource.com/platform/packages/apps/AlarmClock/point come in basically see: Git clone Https://android.googlesource.com/platform/packages/apps/AlarmClock so striking a thing. That's right. We're going to have to download the code directly from this item. 3.2 Copy git clone https://android.googlesource.com/platform/packages/apps/AlarmClock to your "git Bash" window for execution. ---------------------------------3.3 and 3.4 do not necessarily follow----------------------------------------------------------------3.3 If you have a problem with your character, be blocked by the wall appears: UNknown SSL protocol error in connection to code.google.com:443 you have to get a goagent agent. If you are good at Kung Fu. Just take your own ride. But I have a ready-made: But if you have to visit Google at least, otherwise these are the https://code.google.com/p/chromeplus/download good words. Click Google's browser directly. (I know you're not going to use Google Chrome.) Just to open an agent command line, you don't use that browser. Big can be turned off. As long as you do not close that goagent Agent window just fine) 3.4 set Git http.proxygit config--global http.proxy 127.0.0.1:8087 now try 3.2 and you'll see the folder that you want.
