Android：BroadcastListner出现错误

在我的应用中,我一直在检查互联网连接.如果在任何时间都没有互联网,则用户会收到一条祝酒消息.

为此,我正在制作一个NetworkStateReceiver类,该类扩展了BroadcastReceiver类.

Java文件：

public class NetworkStateReceiver extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent); // Here I'm getting the error mentioned below
        Log.d("app", "Network connectivity change");
        if (intent.getExtras() != null) {
            NetworkInfo ni = (NetworkInfo) intent.getExtras().get(
                    ConnectivityManager.EXTRA_NETWORK_INFO);
            if (ni != null && ni.getState() == NetworkInfo.State.CONNECTED) {
                Log.i("app", "Network " + ni.getTypeName() + " connected");
            }
        }
        if (intent.getExtras().getBoolean(
                ConnectivityManager.EXTRA_NO_CONNECTIVITY, Boolean.FALSE)) {
            Log.d("app", "There's no network connectivity");
        }
    }
}

错误：

Cannot directly invoke the abstract method onReceive(Context, Intent) for the type BroadcastReceiver

这是我在应用程序中放入Android清单文件的内容：

<application>    
    ....
    <receiver android:name=".NetworkStateReceiver" >
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
        </intent-filter>
    </receiver>
    ....
</application>

这是我使用的权限：

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" 

为什么在super.onReceive(context,intent);中出现此错误,如何解决呢？

解决方法:

删除行super.onReceive(context,intent).基本实现始终不执行任何操作(这是一种抽象方法).
