Destroy Current Activity using notification Android

Question

MainActivity is opened in My app. Consider this scenario,

when MainActivity(1) is currently running. Notification comes, user clicks and Mainactivity(2) gets opened. It works. When I click back button. Mainactivity(2) gets destroyed. MainActivity(1) is shown to user and app freezes. I was looking for a way to close MainActivity(1).

NotificationManagerCompat manager =   NotificationManagerCompat.from(this);

Intent notificationIntent = new Intent(this, MainActivity.class);

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
    | Intent.FLAG_ACTIVITY_NEW_TASK );

PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
    notificationIntent, 0);

builder.setContentIntent(contentIntent);
manager.notify(123,builder.build());

Instead of that, you could check if MainActivity is running, and avoid creating MainActivity 2. — Fustigador, Feb 26 '20 at 11:39

I just added "singleTop" in the Manifest file. It worked for both scenarios. When an activity is currently display and App is in the background.

  <activity android:name=".MainActivity"
        android:launchMode="singleTop"></activity>
