Is it possible to upload an application to the play market in the GUI of which there is an Exit button that forcibly closes it?

Question

Android

Actually a subject. Or is it bad manners?

Answer 1

It is possible and necessary. So you allow the user to choose to unload the application or leave it in memory to eat resources further. It's not bad manners. Take a pack of top applications and you will see this very button there.

Answer 2

You can, the market will not say anything for it, but it's bad manners.

Answer 3

Of course you can. But it would be more correct to define the logic in the onBackPressed method: there is some kind of dialog to exit (yes / no) or a double tap to exit, etc. This will be more convenient for the user.
