Question

My goal is to return back to last activity if user click in notification.
I create the notification from in the service onCreate() in this way:

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

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

but when I click on the notification this go to the MainActivity and not to the last one opened before to click home button.

In manifest I have tried with the MainActivity with launchMode=”singleTop”, “standard” and “singletask” but without success.

Thank’s.

Use the below code..

 contentTitle = "MyApp";
    contentText = "Reopen App";
notificationIntent = new Intent(this, MainActivity.class);
    contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
    notification.setLatestEventInfo(getApplicationContext(), contentTitle, contentText, contentIntent);

And set the Activity to SingleTop or SingleInstance in Android Manifest, then instead of creating a new activity it just reopen the one still active.
