ICS中的ACTION_USER_PRESENT导致强制关闭

我正在尝试在屏幕解锁时收到事件ACTION_USER_PRESENT。我有一个注册的广播接收器,它应该在屏幕打开时给出一条日志消息,然后解锁。它会显示屏幕上的消息,但会在屏幕解锁期间(用户在场)使应用程序崩溃。

有什么想法吗?我没有运气多次搜索过这个问题。顺便提一下,我在ICS 4.0+上并在多个设备上进行了测试。

这是我的广播

    @Override
        public void onReceive(Context context, Intent intent) {
        Log.d("BRODCASTRECEIVER", "MAIN");

        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
            // do whatever you need to do here
            Log.d("BRODCASTRECEIVER", "SCREEN OFF");
        }
        else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            // and do whatever you need to do here
            Log.d("BRODCASTRECEIVER", "SCREEN ON");
        }
        else if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
            Log.d("BRODCASTRECEIVER", "UNLOCK");
        }
        }
    };

以下是我注册的方式

    IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_USER_PRESENT);
intentFilter.addAction(Intent.ACTION_SCREEN_ON);
intentFilter.addAction(Intent.ACTION_SCREEN_OFF);
    registerReceiver(Receiver, intentFilter);

这是清单

    <receiver android:name=".MyBroadcastReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.SCREEN_ON" />
            <action android:name="android.intent.action.SCREEN_OFF" />
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>
            </receiver>

logcat的
