本文记录了一次在Android应用开发过程中遇到的广播接收器异常问题，详细描述了问题现象及定位过程，包括如何通过标识符判断广播是否已注册，以及在销毁Activity时出现的异常堆栈跟踪。

一脸懵逼，敲的正爽的时候突然“很抱歉，xxx已停止运行”，感觉自己就只做了个json解析，之前注册的广播从未发生此类错误，直到一个小时前，what is？ Who can help me？？？

“该广播接受器已被注销,导致找不到该广播接收器”，这好办，给它加上一个tag标识嘛，如果此广播为注册状态则可解除广播，否则不予理会；but 为什么好好的项目，并没有任何改动广播类的情况下会发生此错误？what is？

private boolean mReceiverTag = false;   //广播接受者标识
//代码中动态注册广播
private void registerExitReceiver() {
    if (!mReceiverTag){     //在注册广播接受者的时候 判断是否已被注册,避免重复多次注册广播
        mReceiverTag = true;    //标识值 赋值为 true 表示广播已被注册
        IntentFilter exitFilter = new IntentFilter();
        exitFilter.addAction(EXIT_APP_ACTION);
        registerReceiver(exitReceiver, exitFilter);
    }
}

private void unRegisterExitReceiver() {
    if (mReceiverTag) {   //判断广播是否注册
        mReceiverTag = false;   //Tag值 赋值为false 表示该广播已被注销
        unregisterReceiver(exitReceiver);   //注销广播
    }

}
