android – 如何从接收器调用服务取决于Internet连接与否？

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

public class updateReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context,Intent intent) {


      Connectivitymanager connectivitymanager = (Connectivitymanager) 
                                   context.getSystemservice(Context.CONNECTIVITY_serviCE );
      NetworkInfo activeNeTinfo = connectivitymanager.getNetworkInfo(Connectivitymanager.TYPE_MOBILE);
      Boolean isConnected = activeNeTinfo != null && activeNeTinfo.isConnectedOrConnecTing();   
      if (isConnected)       
          Log.i("NET","connecte" +isConnected);   
      else Log.i("NET","not connecte" +isConnected);
    }
}
