Ads: Support moving playback from one view/activity to another

Hello, I am trying to find an example using a rather trivial case of screen rotation when playing an ad. But in the examples, the manifest contains:

android parameter: configChanges = "orientation", so when rotate, views does not recreating.

In my case, without android parameter: configChanges = "orientation". When I rotate the screen, I lose information about the advertisement.

To solve the problem, I save playerView and add it to container when views recreate.
But this method looks pretty crutch:
(viewModel.playerView?.parent as ViewGroup).removeView(viewModel.playerView)
findViewById(R.id.container).addView(viewModel.playerView)

Looks like that:

Here's a repository with an example described

Please help me find the correct method when rotating the screen.

Thanks for all your help.
