How do I use this android app

Ok this is a dumb question so sorry in advance.
I have the android SDK and eclipse.
I found this script to interface arduino and android but dont have the first clue on how to import it into the eclipse or run it on my phone.  
I do have my phone connected to the SDK and have been able to run other android demo apps.
