Unregister Receiver无法取消注册onDestroy

-1

我在我的主要活动中使用BroadcastReceiver并将其注册到OnCreate并尝试将其注册到OnDestroy中，但一段时间应用程序崩溃，因为它声明我正试图取消注册已注销的接收器。这里是我的代码：Unregister Receiver无法取消注册onDestroy

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     ... 
LocalBroadcastManager.getInstance(this).registerReceiver(forceLogoutRequest, new IntentFilter(CommonUtils.FORCE_LOGOUT)); 
} 

@Override 
    public void onDestroy() { 
super.onDestroy(); 
if(forceLogoutRequest!=null) { 
      unregisterReceiver(forceLogoutRequest); 
      forceLogoutRequest = null; 
     } 
} 


    private BroadcastReceiver forceLogoutRequest = new BroadcastReceiver() { 
     @Override 
     public void onReceive(Context context, Intent intent) { 
      .. 
      .. 

     } 
    };

这是我收到的控制台：

这可能是接收器被打死你试图杀死它 – Zoe

检查这个https://stackoverflow.com/questions前/ 6165070/receiver-not-registered-exception-error/24391706＃24391706 – tamtom

可能重复[Receiver not registered exception error？]（https://stackoverflow.com/questions/6165070/receiver-not-registered-exception-error ） –

用这个代替

LocalBroadcastManager.getInstance(this).unregisterReceiver(forceLogoutRequest);

有关使用localBroadCastManager更多信息checke此链接https://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager.html

啊，只是在我的代码中找到这个错误。你是对的LocalBroadcastManager注销这个 – user565

是的，如果你使用全局广播，那么你可以直接使用取消注册。任何快乐编码:) – Anonymous

首先为了取消注册接收器，您需要使用LocalBroadcastManager

LocalBroadcastManager.getInstance(this).unregisterReceiver(YOURRECEIVER);

，那么你应该在注销暂停您的接收器，而不是破坏
