Xfinity Stream subscribers have been waiting for Comcast's streaming service to roll out more widely across platforms, including Android TV. While that isn't happening today, we are a step closer.

The Fire TV app clocks in at 43MB, and Xfinity Stream customers can get started with the new beta at the link below, though you can also download it directly over at APK Mirror.
