The graphical layout never works properly when trying to display a MapView. I've used both a Google Maps view and an OSM (Osmdroid) map view in my project. The project works OK but you will have to run it to see how the view comes out. The graphical layout of my views show exactly the same '.. could not be instantiated' error as you have. You will need an API key for you Google map as PM said.

In your Layout image, it seems that you havent put the API key. So put the API key and check it again.
