How to open my application in current state from notification

Question

I need to open app in current state, without any new instance of my main Acitivity

Here is my code

Intent intent = new Intent(baseActivity, MainActivity.class);
    intent.putExtra("FROM_NOTIFICATION", true);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    PendingIntent pendingIntent = PendingIntent.getActivity(baseActivity, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

and

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(baseActivity)
            .setSmallIcon(getNotificationIcon()).setLargeIcon(BitmapFactory.decodeResource(baseActivity.getResources(), R.drawable.ic_launcher))
            .setContentTitle(baseActivity.getResources().getString(R.string.app_name))
            .setContentText(message)
            .setOngoing(true)
            .setContentIntent(pendingIntent);
    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

How can I do this? Or is there another way?

What do you mean by "without any new instance of my main Acitivity"? Where's the old instance? You mean it should not override the 'old' one if you're already in the app..? — Vucko, Mar 29 '16 at 07:34
Yes it is, I'm not beside my laptop at the moment to re-check what I'm using, but I think it was adding `android:noHistory="true"` in your `AndroidManifest.xml` in the `` that you want. If that does not work, I'll have to get back to you in 4h or so :D — Vucko, Mar 29 '16 at 08:51
you want to open the app instance when app is closed and to open the existing instance when you click on the notification . correct ? — Swaminathan V, Mar 30 '16 at 05:57

Try setting flag to the intent as below..

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

instead of

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);

in your code.

Hope this helps you. Let me know for queries.
