Unregister Receiver無法取消註冊onDestroy

-1

我在我的主要活動中使用BroadcastReceiver並將其註冊到OnCreate並嘗試將其註冊到OnDestroy中，但一段時間應用程序崩潰，因爲它聲明我正試圖取消註冊已註銷的接收器。這裏是我的代碼：Unregister Receiver無法取消註冊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) { 
      .. 
      .. 

     } 
    };

這是我收到的控制檯：

這可能是接收器被打死你試圖殺死它 – Zoe

檢查這個https://stackoverflow.com/questions前/ 6165070/receiver-not-registered-exception-error/24391706＃24391706 – tamtom

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

用這個代替

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

啊，只是在我的代碼中找到這個錯誤。你是對的LocalBroadcastManager註銷這個 – user565

是的，如果你使用全局廣播，那麼你可以直接使用取消註冊。任何快樂編碼:) – Anonymous

首先爲了取消註冊接收器，您需要使用LocalBroadcastManager

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

，那麼你應該在註銷暫停您的接收器，而不是破壞
