Swipe between Android activities as with ViewPager?

I tried solution two, but the issue is that a single activity cannot detect which launcher icon was used (please tell me if I'm wrong).

Solution 1: You can swipe in terms of starting the other Activity each time. In this case you should fix the transition animation for the two activities in order to have a "swiping" effect and set the two activities as SingleTask in order not to have multiple instances in your task (thus you should implement the onNewIntent() method).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
