Been putting off sideloading AllCast's SDK to your brand new Amazon Fire TV? Well, friend, your procrastination has paid off. Now, all you have to do to install the casting and screen-mirroring app is download it straight from the Amazon App Store. So long as you also have AllCast installed on an Android device, you can beam photos, videos and music from your phone or tablet to Amazon's set-top box. Plus, you can use the app to view images and videos saved on Google+ and Dropbox. If you don't plan to pick up a Fire TV (waiting for the second one, eh?), you can still use AllCast with a number of other devices, including Chromecast, Xbox One, Roku, Apple TV and a smattering of smart TVs.
