Don't swipe to Homescreen

[Jan78]

Hi guys,

I want to develop a Tutorial and the swipefunction should be explained.
There are a few screens in my Tutorial included the Homescreen.
I show the user the swipe functionality and he should try this also.
But he should only swipe to the next screen and don't leave the Tutorial and go back to the real homescreen.

Does anyone of you have an idea how to solve this issue?
Is there a windows manager or something like this which I have to adapt?

Many thanks in advance for any proposal!

BR, Jan
