I want to program an application which opens the activities in another windows/screens when I tap on a button and when I tap the recents button of the navigation bar I would like to see more screens/windows as like more application would be opened.
I want to see as many app icons as many activies are opened from my app.

I prefer the sample code in android kotlin but I would be happy in android java too.

Sorry for the bad description of my problem.

Please help me.

I tried intent flags to reach my goal but it isn’t working.

intent.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK)
