ClassCastException:com.facebook.ads.redexgen.X.Th.A0I

Hi, I update the audience network sdk to 6.2.1, crash happens on many users' devices, include android 6.0 - android 10. The previous version I use is 5.11.0 and has no this issue.

It's probably happens because you add MediaView directly into Activity root layout (ViewRootImpl). Create some child layout under ViewRootImpl, for example, FragmentLayout and add MediaView inside this layout. It should fix the issue.

I also have this issue. I checked what @gwheet said, but all my MediaViews are inside ConstraintLayouts. This is my stack trace:
