转载：混淆包含SlidingMenu、gson等Android代码的proguard写法

描述：作为一个写了几年c#的码农，咱的java水平实在不敢恭维，但是最近有个任务需要弄点java的代码，还要研究混淆。网上百度并实验了整整一天，终于算是有点成果了。其中混淆的时候由于用到了gson包，导致混淆后代码不能正常执行，看到了这篇文章，摘抄了其中关于gson设置的一段配置，就好了，不敢私藏分享一下。原文转载。

在混淆包含SlidingMenu的代码时，可能会报以下错误：

can't find superclass or interface com.google.android.maps.MapActivity

...

如果还使用到了gson来序列化或者反序列化json，程序还会抛出NullPointerException，这是因为代码被混淆后，成员变量以及getter、setter的名字都变了，这样就不能正常的序列化。

jni同理。

以下是本人使用的proguard.cfg，遇到此类错误的可以参考一下：
