Android scaling Activity or Screenshot + ViewPager?

Question

Android

Please advise on this matter. Let's take as an example any browser (for example, YandexBorwser) for Android, almost every browser has such a function as showing open windows, selecting and switching to an existing one. When you click on the view all windows icon, we see a ribbon of previously opened windows with their contents. So the question is, is it somehow possible to scale all open Activities and line them up in a feed, or does it, for example, work so that when you open a page, a screenshot is immediately taken and stored, and when you click show windows, pictures are lined up simply? Generally prompt as it is better to implement similar.
