I can definitely understand why you have contacted us on the Slingbox Answers Forum in regards to Installing the Slingplayer on your Android Phone. If you have already purchased the application on one Android Phone, you should be able to install it to another Android Phone by going into "My Apps" on the phone you are trying to install it too. It will then be listed under the Applications you have already purchased. Hope this Helps!
Have a Great Day!
