Bagaimanakah saya boleh membuat penerima siaran dalam Android untuk mengesan dan mengendalikan kedua-dua perubahan sambungan Internet dan kehilangan Internet secara tiba-tiba?

<code class="java">public class NetworkChangeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {
        // Check the connectivity status
        int status = NetworkUtil.getConnectivityStatusString(context);
        Log.e("Network reciever status", String.valueOf(status));
        // Perform actions based on connectivity status
        if (status == NetworkUtil.NETWORK_STATUS_NOT_CONNECTED) {
            // Handle no internet connectivity
            new ForceExitPause(context).execute();
        } else {
            // Handle internet connectivity restored
            new ResumeForceExitPause(context).execute();
        }
    }
}</code>
