Android Question Demo showing GoogleMapExtras working with GoogleMap

[Homerclese]

I've been searching but I can't find a demo showing how GoogleMapExtras works with GoogleMap. For example, when I add markers to my GoogleMapExtras instance, they don't appear on my GoogleMap instance.

Here is a code fraqment:

          Dim MarkerOptions1 As MarkerOptions
            MarkerOptions1.Initialize
            MarkerOptions1.Position2(mylat,mylon).Snippet("").Title("Hello World").Visible(True)
            MarkerOptions1.Icon(BitmapDescriptor1)
            MarkerOptions1.Anchor(0.5,0.5)
            Dim Marker1 As Marker=GoogleMapsExtras1.AddMarker(GoogleMap1, MarkerOptions1)

Thank you and I found that code, but I don't get markers. If I use the GoogleMap markers, I get markers. But I specifically want to use the features of GoogleMapExtras.
