android building problem

Hi everyone. I downloaded the Android SDK root folder. but when i'm build my game and after selected the Android SDK folder. the building is done. but then it gave me an error;No android device found. If you are sure the drivers is attached then it might be USB driver problem. For detail please check Android SDK Setup section in unity Manual.

What should i do? I'm using Windows.

Please help

Have you attached an actual device (phone, tab) to your PC? Is USB Debugging switched on in the application settings of your phone, sub menu for development?

The section regarding installing an USB driver is this one:
