As long as your Android Mobile device meets or exceeds the requirements, you should not have issues getting the SlingPlayer Mobile application working on it.
The following link will provide you with the information to check.
Devices and Requirements
I just tested with Slingbox Solo + Epic 4G + Slingplayer.
It works. But a little bit disappointed. I currently have Sony LF-V30 + Sony PSP to watch TV. Slingplayer quality is not as good as PSP locationfree. I also tested on Ipod Touch 3g and PSP quality is far superior.
I could watch TV on my PSP from my patio but I would not do the same with Slingplayer mobile.
