How to apply onConfigurationChanged () in activity with AndroidXMapFragment

I modified onConfigurationChanged () in the Search sample code as below to not restart the activity when orientation changes. However, it always dies with the error shown below. Is there any way to solve this?

OnConfiguration method implementation looks correct. Are you trying to inflate a fragment... inside a fragment_layout?

Note: You cannot inflate a layout into a fragment when that layout includes a . Nested fragments are only supported when added to a fragment dynamically. Please try enabling debug mode to locate the exact error.
