Remove notification after clicking

Question

Easy, simply call this:

mBuilder.setAutoCancel(true);

Also, while it's not really necessary, if you really want to use FLAG_AUTO_CANCEL, just call this before you call mNotificationManager.notify:

mBuilder.build().flags |= Notification.FLAG_AUTO_CANCEL;

Try this....

NotificationManager mNotificationManager =
    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

 ..........
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.push_notify_icon)
            .setContentTitle("New Question!")
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
            .setAutoCancel(true).setContentText("" + QuestionData.getAuthor().getUserName() + ": " + QuestionData.getQuestion() + "");
mBuilder.setContentIntent(contentIntent);

    ..............        


mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
mNotificationManager.notify(0, mBuilder.build());

Here is notification:

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_calendar)
            .setContentTitle("My Firebase Push notification")
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(soundUri)
            .setContentIntent(pendingIntent);

the key behind cancellation on click is:

            .setAutoCancel(true)

i hope it resolves the matter.

You can add a flag to your notification:

http://developer.android.com/reference/android/app/Notification.html#FLAG_AUTO_CANCEL

This will dismiss it upon clicking.

In kotlin, you can use:

mBuilder.build().flags.and(Notification.FLAG_AUTO_CANCEL)
