谁能告诉我为什么我在logcat中收到此错误？

Question

我是Android的新手，请告诉我以下log cat错误是什么意思，如何消除它？ 在我的应用程序中，我正在阻止不必要的呼叫。当我在使用我的应用程序时按下后退按钮时，出现此错误。 请帮忙

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

    }

取消注册：

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

除非我按返回按钮，否则一切都正常。

Answer 1

您没有显示代码，所以这是一个猜测。

线索在这里：

05-18 16：58：32.614：E / ActivityThread（3265）：活动com.deepthi.blockmycalls.BlockMyCallsActivity泄漏了最初在此处注册的IntentReceiver com.deepthi.blockmycalls.BlockMyCallsActivity$1@44efa3a8。 您是否缺少对unregisterReceiver（）的调用？

活动结束后，您要注销接收器吗？

@Override
protected void onPause(){

    super.onPause();

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

Answer 2

是的，您拥有不释放/取消注册的资源，需要更多代码才能具体说明

Answer 3

如果您可以发布代码，也许会更容易为您提供帮助，但似乎您正在两次注册接收者。
