错误日志：

java.lang.RuntimeException:Unable to resume activity {com.liyuhuyu.liyu/com.liyuhuyu.liyu.ui.activity.DeviceStateActivity}: org.greenrobot.eventbus.EventBusException: Subscriber class com.liyuhuyu.liyu.ui.activity.DeviceStateActivity and its super classes have no public methods with the @Subscribe annotation

解决办法：

1，注册接受事件的组件或者类中没有添加接收事件的方法（例如我的finishActivtiy方法）或者接收事件的方法没有加@Subscriber 注解；如果还是没有解决，请看2

    @Subscribe(threadMode = ThreadMode.MAIN)
    public void finishActivity(DeviceStateBean deviceState) {
        finish();
    }
复制代码

 2，查看接收事件的方法中是否设置了参数，参数为引用数据类型；没有设置参数也是会报以上错误的
