Now that Sling TV invitations have finally begun arriving to select customers, Amazon Fire TV and Fire TV Stick owners are facing the unfortunate truth that the Fire TV version of Sling’s Android app is not yet available. On Sling TV’s FAQs page, the Fire TV and Fire TV Stick are listed under a “Coming soon” section along with most Roku devices, PC, Xbox One, and the Nexus Player. At this point, only Mac, iOS, Roku 3, and Android tablets & phones are supported.
The good news is that several people have let me know that sideloading Sling TV’s Android app on to the Fire TV works surprisingly well. So if you’ve already received your Sling TV invitation and have signed up for the service, you can download their Android app from this link and try it out while you wait for the official Fire TV app to be released.
