running emulator on eclipse not working

Im new to eclipse. I was following a tutorial on youtube, http://www.youtube.com/watch?v=m-C-QPGR2pM, which creates a flash light app on eclipse. When I was trying to run it was not working. When selecting run as : android application a pop up screen appeared.

No compatible targets were found. Do you wish to add a new virtual android device?

I do not know what to do at this point.

The tutorial does not 开发者_JAVA技巧have this problem.

For running an Emulator instance, you will have to create a virtual android device. For this you will need the AVD - In Eclipse click "Window -> Android SDK and AVD manager" Click create new AVD and this screen will pop up. Create the virtual device and your ready to go.
