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:
