Question

Well, I have a simple notification. But when I tap it in Notification bar, I just get opened my app. So how can I know that my app was opened by notification tap or how can I open a specific Activity after tapping?

I think you have this code in Statusbar Notification. When you click the Notification Item, the following Intent is called.

    Context context = ctx.getApplicationContext();
    Intent notificationIntent = new Intent(ctx, ctx.getClass());
    PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, notificationIntent, 0);
    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

If you want specific Activity to be opened, call the particular Class in the above Intent
