Android EventBus 报错 xxx and its super classes have no public methods with the @Subscribe annotation

出现此错误的原因之一：代码混淆后，无法识别 @Subscribe annotation。

解决方法：proguard config file文件添加如下配置：

-keepattributes *Annotation*
-keepclassmembers class ** {@org.greenrobot.eventbus.Subscribe <methods>;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }
