at com.android.internal.policy.DecorView.onMeasure(DecorView.java:834)项目中为了安全考虑，添加了混淆。没想到开启混淆后，在proguard-rules.pro文件写了一些混淆规则。但是没想到，还是出现了问题。原来是我项目中的EventBus出现的问题，然而，我已经将EventBus防混淆规则写了，为啥还是出现问题。百思不得其解。看了一下log。发现原来是没有@Subscribe这个注解。我明明已经添加上去了啊。我想，很有可能是混淆将我的注解给混淆掉了。怎么办呢。这时，我看到了一篇帖子：https://stackoverflow.com/questions/35874055/eventbus-subscriber-class-and-its-super-classes-have-no-public-methods-with-th
大神上面有一个防止这个@Subscribe注解被混淆的一个规则
-keepattributes *Annotation*
-keepclassmembers class ** {
@org.greenrobot.eventbus.Subscribe ;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }
感谢大佬，添加完这个规则后，我的项目正常运行了。
