Good evening/night!
I am Brazilian.


Error:
E/AndroidRuntime: FATAL EXCEPTION: main
java.lang.IllegalArgumentException: No view found for id 0x7f0801e6 (com.example.applicationviewpager:id/lay_Interno) for fragment InternoFragment{d5fa25a} (f3e8a24f-1a76-4426-8021-3ff3d5fb5d1b id=0x7f0801e6)


Below is the link of 2 very simple projects that were developed using Android Studio to exemplify the error.
Project 1:
ApplicationNavigationDrawer that use FrameLayout:
https://drive.google.com/file/d/1z3qRcFEYpsE5ZKhp0zODPL4Pxe1W8aMR/view?usp=drive_web.

Project 2:
ApplicationViewPager that use ViewPager2:
https://drive.google.com/file/d/17bedOcyK1p6F3jDK8_ZU7DUZf2zXjc7r/view?usp=drive_web

Open and run both projects to compare and check for the error.


Procedure:
Do the following:
Open and run project 1, using the navigationDrawer access the 2nd fragment, then rotate the device screen.

Result:
No mistakes.

Comments:
Through the getFragment function located in MainActivity.class I always return a valid Fragment (which has a view).

Now do the following:
Open and run project 2, swipe the screen to the left to access the 2nd fragment, then rotate the device screen.

Result:
E/AndroidRuntime: FATAL EXCEPTION: main
java.lang.IllegalArgumentException: No view found for id 0x7f0801e6 (com.example.applicationviewpager:id/lay_Interno) for fragment InternoFragment{d5fa25a} (f3e8a24f-1a76-4426-8021-3ff3d5fb5d1b id=0x7f0801e6)

Comments:
When rotating the device screen, the createFragment function located in PaginaAdapter.class does not return a valid fragment.

I'm novice developer but understand that some android features like: Fragment, RecyclerView, etc need a valid view to use as a base.
So I would like some help to make this ApplicationViewPager which uses ViewPager2 work correctly similar to the ApplicationNavigationDrawer which use FrameLayout.
