经过3.0+ 版本不开源，终于等到4.0的开源，也可以看看4.0的绚丽界面实现的source了。
?
源码下载地址：（参考google文档）
http://source.android.com/source/downloading.html
?
过程中 repo sync -j16 代码同步不下来 (链接有问题？) 先不管咯。
?
迫不及待，先看看android-4.0.1_r1里源码包含了什么。
?
先把manifest clone ? 下载下来看看。
?
$:?git clone https://android.googlesource.com/platform/manifest -b android-4.0.1_r1
?
wait...
?
ok
$ cd manifest/
$ cat default.xml

还没看到源码，红色部分应该是新添加的。绿色的主题也有改进。新的界面应该在luancher2 和systemUI 下。?

等待中...

中断后在重新下载 repo sync -j16
据说4.0编译环境比较苛刻。现在我还没下完。等下完之后才知道什么情况
感谢手机先生网的投递
新闻来源:solidot
新一代的智能手机也许更轻更小巧，但它们的操作系统则走向另一个极端。Android 4.0 Ice Cream Sandwich（ICS）编译源代码将需要工作站内存不低于16GB，是编译Gingerbread的两倍。
如果开发者想编译ICS，他需要准备： 单次构建需25GB空间，同时编译所有AOSP(Android Open Source Project)配置需要80GB空间，16GB以上内存，在二个四核处理器2.4GHz机器上完成单次构建需5+小时CPU时间，经过时间（wall time）25+分钟。如果开发者需要多个分支，那么空间会很容易突破250GB以上。
