任何人都可以告訴我爲什麼我會在logcat中得到這個錯誤？

我是Android中的新手。請告訴我以下日誌貓錯誤意味着什麼，以及如何擺脫它？在我的應用程序中，我正在阻止不需要的調用。當我在使用我的應用程序時按下後退按鈕時，出現此錯誤。請幫助任何人都可以告訴我爲什麼我會在logcat中得到這個錯誤？

我的代碼：

@Override 
    public void onCheckedChanged(CompoundButton arg0, boolean arg1) { 
     // TODO Auto-generated method stub 

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

       Bundle extra=intent.getExtras();//new 
       telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
       if(extra!=null)//new=== getting the blocked number

     telephonyManager.listen(new MyPhoneStateListener(), PhoneStateListener.LISTEN_CALL_STATE); 
     }//onReceive() 

     class MyPhoneStateListener extends PhoneStateListener 
      { 
       public void onCallStateChanged(int state, String incomingNumber) 
       { 

        switch (state) 
        { 
         case TelephonyManager.CALL_STATE_RINGING: 
          if (true) // if incomingNumber need to be blocked 
          { 
           if(Enable_chkbox.isChecked()) 
           { 
           try { 
           end_call=telephonyService.endCall(); 
           if(end_call==true) 
           {       
            android.telephony.SmsManager sms = android.telephony.SmsManager.getDefault(); 
            sms.sendTextMessage(number, null, SMS, null, null); 
           } 
           Toast.makeText(getApplicationContext(),"Enabled", Toast.LENGTH_LONG).show(); 
           } catch (Exception e) { 
           // TODO Auto-generated catch block 
           e.printStackTrace(); 
            }//try catch 
          }//if chkbox enabled 
          } 
          break; 
         default: 
          break; 
        } 
        } 
       } 

      };//Broadcast receiver 
      IntentFilter filter= new IntentFilter("android.intent.action.PHONE_STATE"); 
      registerReceiver(CallBlocker, filter); 

    }

註銷在：

@Override 
protected void onDestroy() { 
    // TODO Auto-generated method stub 
    super.onDestroy(); 
    unregisterReceiver(CallBlocker); 
    this.finish(); 
     Toast.makeText(getApplicationContext(), "text", Toast.LENGTH_LONG).show(); 
     }

一切工作正常，除非我按後退按鈕..

你有註冊接收器，但我想你忘了取消註冊該接收器..請取消註冊該... –

我已經註銷我的接收器.. – Deepthi

@ user1362681 - 只是一個樣式點 - 在Java中，總是以小寫字母開始變量。大寫的名字通常保留給類型。 – derekerdmann

是啊，你有一個資源你不發佈/取消註冊需要更多代碼才能具體

Metnik：謝謝你的迴應。我只注意到你的答案被某個人拒絕了。所以，無論如何，從我作爲一個相關的猜測upvote沒有幫助我。我已經用我的代碼更新了我的問題。請幫助:( – Deepthi

我想我會做一些完全不同的事情在你的情況。我不，也許這只是我，看看你爲什麼你的代碼做你的廣播公司這是更安全，更容易，添加他們在xml中。哪個android也告訴你是最好的。 –

非常感謝Anders Metnik ..我會嘗試一下然後.... – Deepthi

你沒有顯示你的代碼，所以這是一個猜測。

的線索是在這裏：

05-18 16：58：32.614：E/ActivityThread（3265）：活動com.deepthi.blockmycalls.BlockMyCallsActivity已泄漏IntentReceiver [email protected]最初在這裏註冊。你是否錯過了對unregisterReceiver（）的調用？

當您的活動完成後，您是否註銷您的接收器？

@Override 
protected void onPause(){ 

    super.onPause(); 

    if (myMessageReceiver != null){ 
     unregisterReceiver(myMessageReceiver); 
     myMessageReceiver = null; 
    } 
}

感謝您的回覆，但我已經註銷它 – Deepthi

我已經更新了我的問題與我的代碼。請幫助 – Deepthi

呵呵，爲什麼？ – Simon

如果您可以發佈您的代碼，也許會更容易幫助您，但似乎您註冊了兩次接收器。

感謝您的回覆。我只註冊了一次。我已經更新了我的問題和代碼.. – Deepthi

@ user1362681我仍然想想你註冊兩次之前註銷。也許當你推回按鈕OnCheckedChange再次調用。嘗試放置一個斷點和調試應用程序。 – gutiory

@gutiory增加了投票，因爲我認爲當有人進來並投票給我們，當我們試圖解釋而沒有看到代碼時，這是一種恥辱。也發生在我身上。 –

任何人都可以告訴我爲什麼我會在logcat中得到這個錯誤？
