testing on an android device

hi, how would i come about to testing my code on an actual android device. I know how to deploy to an iphone, just change playersetting to ios and build and run with device attached. Then unity will run xcode for me. However, for android, i have eclipse set up for android development and sdk. Is it just simple as just pressing "build and run"? I know for ios i need to get all the development certificate and provisioning file and all that. Are those steps necessary on android as well? I am getting my hand on a android license tommorw but i want to make sure.

Regards
