单击通知时，应用程序不启动或调用onNewIntent

Question

I'm successfully sending notifications using GCM, but when I click on them, nothing happens. Here is the code in my listener, I can verify that it is executing, but when I put breakpoints on the onCreate and onNewIntent methods in my HomeActivity they are never hit. In addition, if that application is not running, I still receive the notification, but the application is not launched. I have tried suggestions from here and here as well as several different combinations of Intent flags. Am I missing something? Please ask if you need me to post more code.

Code from my GcmListenerService

    notificationBuilder = new NotificationCompat.Builder(this)
            .setContentTitle(getString(appNameID))
            .setContentText(payload)
            .setSmallIcon(iconID)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), bigIconID));

    Intent resultIntent = new Intent(this, HomeActivity.class);
    resultIntent.putExtra(HomeActivity.NOTIFICATION_ID_KEY, notificationID);
    resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
    resultIntent.setAction(HomeActivity.NOTIFICATION_ACTION);
    PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    notificationBuilder.setContentIntent(resultPendingIntent);

    // Set Vibrate, Sound and Light
    int defaults = 0;
    defaults = defaults | Notification.DEFAULT_LIGHTS;
    defaults = defaults | Notification.DEFAULT_VIBRATE;
    defaults = defaults | Notification.DEFAULT_SOUND;
    notificationBuilder.setDefaults(defaults);
    notificationBuilder.setAutoCancel(true);


    // Post a notification
    notificationManager.notify(NOTIFY_ID, notificationBuilder.build());

have you added android:launchMode="singleTop" in your manifest. and also add intent.FLAG_ACTIVITY_SINGLE_TOP

UPDATED

Aadd android:exported="true" to your manifest, That might solve your problem.
