Subscriber class XXX and its super classes have no public methods with the @Subscribe annotation

Caused by: org.greenrobot.eventbus.EventBusException: Subscriber class com.pdxx.yxzp.main.student.exercise.ExerciseActivity and its super classes have no public methods with the @Subscribe annotation

eventbus 異常 , 你發現在 base 類中 , 明明進行了   EventBus.getDefault().register(this); , 在子類中用的時候還是出錯 , 是因爲判斷你沒有進行 , 

@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(Object myEvent) {

}

即使你不用也要添加這個 , 在父類中也要使用 , 不然就要報錯 , 在子類中就不用再進行註冊了
