Looking at your screenshot I think you should unselect all the AVDs displayed on the list. The option you chose launches the best selected AVD by default, and optionally a device.
Also, the Genymotion instances are considered as real devices by ADB and ADT. So, as GhostDerfel mentioned, you need to run one of them before running your app on Genymotion instance.
To know all the detected devices by ADB you can look at the "Devices" section of DDMS. If a Genymotion device is detected, it should show a name like this : genymotion-galaxy_s3....
You can also run this command adb devices
. The result should show something like this:
List of devices attached
192.168.56.102:5555 device
Each Genymotion machine is listed by its local IP address here.
If you can't find your Genymotion instance(s), check that you have the lastest version of Genymotion. A ADB detection bug has been fixed on the release 2.0.2
