Technically, it is possible to embed Google Maps data into the Viewer. However, from a legal/licensing standpoint the answer is a little more complicated.
The solution proposed in the Rex Hansen article is very interesting and useful for mobile applications but too limited for a web application (ex. image size 640 x 640) as he highlighted in his article.
What about the use of ArcGIS JavaScript Extension for Google Maps to take advantage of interoperability provided by this API? This is certainly legal. But possible?
if you want to see a sample application you can look at the http://www.cbsmerkezi.com/esrigoogle. But I dont know anythink about licensing constraints for usage of google maps api.
I use ArcGIS viewer for Flex 2.2. In it I put my maps but I want to sprinkle and maps from Google. I saw the application's web: http://www.cbsmerkezi.com/esrigoogle I wonder whether sible to take the project.
Well, i'm not able to share the whole project with you but i can mention about how it is done. There exist two map objects in a canvas which Esri map object is over the Google map object. Any extend modification of the Esri map object updates the Google map object, too. To provide these extend transformations, you can use Esri' s project method of geometry service and WebMercatorUtil.geographicToWebMercator function which is in Esri Flex library.

That is a nice piece of work. Is there some manner to configure a single Google basemap into the Flex viewer? Is sounds to me like there is a significant level of customization involved with creating the dropdown lists.
