The problem is, in Eclipse, the new >> Project >> Android >> Android Application Project >> BlankActivity
does not create any Activities in
I had the same problem. I tried installing the ADT plugin + Eclipse bundle and when I tried their "My First App" example Eclipse would not create an activity.
Manually installing Eclipse first and then adding the latest ADT plugin worked for me.
Eclipse does automatically create new activities and I can run the application on an actual device.
Hope that helps.
