java.lang.InstantiationException：类没有零参数构造函数

我正在尝试使用aBroadcastReceiver作为内部类来跟踪网络状态，但是标题中出现了异常。我应该怎么做才能解决这个问题？

public class NetworkChangeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        final ConnectivityManager connMgr = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);

        final android.net.NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
        final android.net.NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

        if (wifi.isAvailable() || mobile.isAvailable()) {
            setupData();
            Log.d("Netowk Available ", "Flag No 1");
        }
    }
}
