Can I make the google maps layer as the base layer and add AGS layer on it?

Question

In Android programming, Can I make the google maps layer as the base layer and add AGS layer on it with the AGS SDK for Android?

If I can , Could you help me by giving me a strategic outline of it? Which example can help? can I implement this by following the sample  Adding a Bing Maps layer sample    ?
However, this sample is add another layer on the AGS base layer. Now what I want to do is to add an AGS layer to a google Map layer.

Thanks a lot！
But I still have one doubt. Can't I use both google maps API and ArcGIS Runtime for Android in one project? In that way, still can't I do it?

I guess if you wanted to have two separate Map Views you could (stacked in a Linear Layout).  Both Esri and Google have their own MapViews and their is no way to add Google Tiles to Esri's MapView (as previously described) and there's no way to add ArcGIS Map Services  to the Google MapView.

The short answer is, No.  Doing so is a violation of the Google Maps Terms of Service:

Check out this FAQ as well (especially the part about acessing the maps and satellite images directly):

Apparently the only way to do this legally is to use the Google Static Maps API.

While not immediately relevant to Android, Rex Hansen posted a nice blog about doing this using the Silverlight API:

Hope this helps.
