android - IntentService 使用 NativeScript 和 Angular 处理 FCM

Question

我想使用 NativeScript + Angular 应用程序创建一个 IntentService，以便该服务在应用程序未运行时生成 FCM 通知。这是我在 Java 中为使用 GCM 推送通知的同一应用程序提供的一些代码。

public class MyBroadcastReceiver extends WakefulBroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // Explicitly specify that GcmIntentService will handle the intent.
    // Start the service, keeping the device awake while it is launching.
    startWakefulService(context, (intent.setClass(context, MyService.class)));
    setResultCode(Activity.RESULT_OK);
}}

这是我的 IntentService 的样子

public class MyIntentService extends IntentService {

public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
public static final String TAG = "GCM";

public MyIntentService() {
    super("MyIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    if (!extras.isEmpty()) {  // has effect of unparcelling Bundle
        /*
         * Filter messages based on message type. Since it is likely that GCM will be
         * extended in the future with new message types, just ignore any message types you're
         * not interested in, or that you don't recognize.
         */
        if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
            sendNotification("Send error: " + extras.toString());
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
            sendNotification("Deleted messages on server: " + extras.toString());
        // If it's a regular GCM message, do some work.
        } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            // Post notification of received message.
            String message = intent.getStringExtra("Sample");
            sendNotification(message);
        }
    }
    // Release the wake lock provided by the WakefulBroadcastReceiver.
    MyBroadcastReceiver.completeWakefulIntent(intent);
}

// Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) {
    mNotificationManager = (NotificationManager) this
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Log.i(TAG, "Inside SendNotification");
    try {
        Intent intent = new Intent(this, MainActivity.class);
        intent.putExtra(Constants.MESSAGE, msg);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                intent, PendingIntent.FLAG_UPDATE_CURRENT);

        String[] lines = msg.split(System.getProperty("line.separator"));
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this)
                .setSmallIcon(R.drawable.store_icon)
                .setContentTitle("Sample Notification")
                .setAutoCancel(true)
                .setContentText("Text");


        Uri alarmSound = RingtoneManager
                .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        mBuilder.setSound(alarmSound);

        mBuilder.setVibrate(null);
        mBuilder.setContentIntent(contentIntent);

        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

    } catch (Exception e) {
        Log.i(TAG, e.getMessage());
    }

}
}

可以使用 NativeScript 实现类似的代码吗？有可用的样品吗？
