I use Xamarin.GooglePlayServices.Maps - it looks like generated binding miss JNI interop constructor (IntPtr, JniHandleOwnership).

System.NotSupportedExceptionUnable to activate instance of type Android.Gms.Maps.MapView from native handle 0x25 (key_handle 0x2ce3cf2b).

Please add this constructor inside Binding Addition class.

PS: I know we should avoid this constructor - but in this case it's MapView - it's "touched" by activity life-cycle so JNI constructor is "must be feature".

I believe this was fixed in (and certainly newer versions).
