How to switch screens correctly

I see many issues done by users because they switched screens not correct.

This below is now just one of many other solutions:

If you dont open/close screens correct your app will get possible runtime errors.

Possible errors: (example)

Unable to add window -- token [email protected] is not valid; is your activity running?

Iam sure you don’t want that.

Then please do it in the future and switch screens correct.
