Displaying android SurfaceView over Unity scene on Android
I have a Unity project(Unity version 2018.4.6f1) and advertising module as an android plugin. To display ads I use container (FrameLayout) and attach this container to UnityPlayerActivity. Everything is fine when I deal with banner views of variety of ad networks. 
But when I try to display Native ads from admob there is an issue with com.google.android.gms.ads.formats.MediaView it is transparent ad even makes container transparent. I suppose that under the hood MediaView uses SurfaceView and tried to display SurfaceView over Unity scene and it is also not displayed. 
As far as I can see with LayoutInspector, UnityPlayer holds a SurfaceView and I guess it uses SurfaceView to render Unity scene there. So I tried to draw admob native ads over SurfaceView without Unity and it works fine.
Maybe someone knows why this can happen and if it is possible to do something?
