Question

I got an app that runs ok, after running proguard the app won't start, I get the following

 UNCAUGHT EXCEPTION : java.lang.RuntimeException: Unable to start activity
 ComponentInfo{com.**/com**Activities.MainActivity}: 
 android.content.res.Resources$NotFoundException: Resource ID #0x0 stack =  
 java.lang.RuntimeException: Unable to start activity

我不是 100% 确定，那是很久以前的事了，但我想我需要告诉 proguard 保留一些类的名称，并且不要混淆它们的命名空间。

如果您尝试访问不存在的资源（通常是错误的）并且与 MainActivity 无关，则会发生这种情况。在这种情况下，错误消息非常具有误导性。
