This may be due to a lack of AVD being selected or created for your project. Check the run configuration you have set up and under the 'target' tab, make sure you have at least 1 AVD available and selected. Several ways to get there, but you can use Project->Properties->Run/Debug Settings ... once there, double click your project name.
