自制android1.5的源码包

最近打算玩下android，听hong老大说最好看看源码。而android官方并没有提供直接可用的。

具体参考如下：
http://www.williamhua.com/2009/04/29/git-and-repo-for-dummies/
http://blog.michael-forster.de/2008/12/view-android-source-code-in-eclipse.html

注意：在做sources.zip的时候不能是用主干来做，要切换到origin/android-sdk-1.5_r3分支下，我是这么做的

$ git checkout origin/android-sdk-1.5_r3 -b sdk1.5r3

否则在debug的时候会定位错误; 今天刚接触这东西，不熟瞎试的，好像还要在.repo/manifest/目录下能执行上面的命令

另外用mike's blog里的python抽取java源文件好像太多了，我稍微修改一下，把android.jar包里面没有的java类都去了。

在自己建的源代码根目录建get_source.py这么个文件：

Python代码

DST_FILE='sources.zip'
CLASS_FILE_PATH='/home/don/desktop/android/'

printDST_FILE,"alreadyexists"
exit(1)
zip=zipfile.ZipFile(DST_FILE,'w',zipfile.ZIP_DEFLATED)

ifzippathnotinwritten:
written[zippath]=1
zip.write(path,zippath)
break;
zip.close()

对python不熟，不知道怎么读jar文件，我把android.jar解压到了桌面。运行上面代码就能生成干净的sources.zip了。

将sources.zip解压到 sdk目录下platforms/android-1.5/下即可

android-1.5下会多出一个sources文件，源文件就在里面了，重启eclipse就可以用了。

我把android1.5的源码包放附件里了，省得大家再做了。
