It's officially available as part of the Android Studio SDK, but that can be daunting to set up if you're not a programmer, so it's best to use a third-party installation tool. The first step is to install ADB on your computer. However, since it's a bit difficult to use ADB over a USB connection with Fire devices, it's best to do it over a Wi-Fi connection. Like all Android devices, you can use the Android Debug Bridge (or ADB, for short) to transfer APKs to a Fire TV device. It's available from the Play Store, and can copy APK files or your phone's own applications to your Fire TV. There are a few mobile apps that can copy applications to a Fire TV device, but the best option is Apps2Fire. Install APKs from an Android phone or tablet Still, you probably won't know if an app works until you try it, so we've put together this guide on how to sideload any Android app (in APK format) onto your Fire TV. Finally, some Fire TV models run fairly old versions of Android (even the latest Fire TV Stick uses Android 7.1, released from 2016), so applications that require newer OS features may not work properly.

Also, the Fire TV doesn't support Google Play Services, which some software uses for notifications, licenses, and other functionality. First, Fire TV devices aren't fully compatible with all Android apps - many games and apps are designed for a touchscreen, not a physical remote.

However, there are a few caveats to the process.

While the built-in Amazon Appstore does have a wide selection of apps and games, you can still install software not available through the official store (like the Kodi Media Center) if you have the APK file. Amazon's Fire TV devices run a heavily-modified version of Android, which means you can install some Android applications on it.
