ant script to obfuscate android code

本文主要是介绍ant script to obfuscate android code，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

最近正在做CHINA区的build machine. J2ME已经开始大规模使用，公司最近要支持OPHONE手机，于是也把ANDROID支持到buildmachine里去。

android有自己的anttask.jar，没有SDK源码，于是想反编译anttasks.jar来获得，结果反编译后有些问题。所以只得自己硬着头皮写一个了。

网上有一哥们写了一个，不过拿下来有几个target没有，比如package-resource，所以自己写了个完整的。代码混淆也加上了。
