android - 谁能告诉我为什么我会在 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，我该如何摆脱它？在我的应用程序中，我正在做的是阻止不需要的呼叫。当我在使用我的应用程序时按下后退按钮时，我收到了这个错误。请帮忙

                           break;

                  }
                }

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

    }

注销：

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

除非我按后退按钮，否则一切正常。

您没有显示您的代码，所以这是一个猜测。

线索在这里：

05-18 16:58:32.614: E/ActivityThread(3265): Activity com.deepthi.blockmycalls.BlockMyCallsActivity 泄露了最初在此处注册的 IntentReceiver com.deepthi.blockmycalls.BlockMyCallsActivity$1@44efa3a8。您是否错过了对 unregisterReceiver() 的调用？

当您的活动结束时，您是否正在注销您的接收器？

@Override
protected void onPause(){

    super.onPause();

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

是的，您有一个不释放/取消注册的资源需要更多代码来具体说明

如果您可以发布您的代码，也许会更容易为您提供帮助，但您似乎注册了您的接收器两次。
