很多人不懂，说明下：Android是google主导开发的一个手机系统，基于linux。具体可以看 http://code.google.com/android/

由于有模拟器，所以前几天看了这个系统。发现里面有几首铃声很不错，非常hit-hop，于是乎就想把这些铃声搞出来。

试了几下，发现正常方法没法打开和读取system.img。这样的情况下只能考虑如何hack进系统内部了。

问了TK教主，教主提供了一个方法，telnet进去。后来发现不行，但给我提供了另外一个思路。

Android用了qemu做emulator，qemu带了一个参数：-console（已经被-shell取代）。于是乎，我进去了。。。

进去后发现系统没jail（google比apple厚道多了），但自带的bin和sbin少得可怜，连cp都没有。找来busybox，搞定。
