Amazon has given users the ability to sideload .APK files to their Fire TV. This means you can sideload Android apps to your Fire TV. However, since the Fire TV does not support touch screen capabilities, only specific apps will actually work properly on the device. Here is a list, including download files, of the top apps that you should sideload to your Amazon Fire TV. Please read the tutorial here on how to sideload apps to your Amazon Fire TV.
