一键删除android下面无用资源

项目需求一改再改，UI一调再调，结果就是项目中一堆已经用不到但却没有清理的垃圾资源，不说工程大小问题，对新进入项目的人或看其他模块的代码的人来说，这些没清理的资源可能也可能会带来困扰，所以最好还是清理掉这些垃圾，对于一个稍微大一点的工程来说，手工清理明显是不现实的，这就需要一个方法做这些事情。

本人最怕码字，上面内容引入

关于android lint的使用，如果不了解的请自行去了解。

下面是我的清除代码，主要就是使用dom 节点解析来删除无用资源，需要引入dom.jar ,建议到这个仓库去下载，，速度还可以。代码没有做优化，临时写的。

不义而富且贵，于我如浮云。
