UPDATE, 6/15/2018:Kodi on Amazon Fire TV is vulnerable to infection from a nasty cryptocurrency-mining malware called ADB.Miner. There are ways to uninstall the malware, but this should serve as a stark reminder that there are always risks when allowing third-party app installations on Android devices.
When it comes to managing your own media, few programs can offer as much as Kodi (formerly called XBMC and, before that, Xbox Media Center). You can organize your movies, TV shows and photos; you can install clever add-ons; and you can record live television.
If only installing it were as easy as using it. While Kodi is simple to install on a computer, getting it for a streaming box or stick is somewhat tougher. That’s ironic, considering the app’s interface is optimized for TV screens. Still, installing Kodi on a Fire TV or Fire TV Stick is easier than you might think. You don’t have to root your device, and you can accomplish the whole process in about 5 minutes, if you’re a quick typist.
1. Access your device settings.
In the Settings menu, click Device. This is where you can control your app installation permissions.
2. Click on Developer Options.
It should be the second option on the list.
3. Enable Apps from Unknown Sources.
If this setting is off, click it once to turn it on.
WARNING: Allowing installation of third-party apps can be a sizable security risk, as Amazon points out. In fact, Kodi installations on older Apple TVs were trivial to compromise. Installing Kodi on a Fire TV device involves a trade-off between security and convenience. Weigh your options carefully before installing.
There is also an outside possibility that installing third-party apps could cause your device to malfunction. If it does, simply factory-reset it and try a different installation. (If you're willing to take the risk again, that is.)
4. Acquire the Downloader app.
There are multiple ways to install Kodi, but the simplest way is with the free Downloader app. You can find it in the Amazon Appstore.
5. Direct Downloader to the Kodi website.
The best URL to use is http://www.kodi.tv/download, but you can use other sources, if you prefer.
6. Select the Android app.
The Fire TV’s operating system is an Android branch, so the Kodi Android app will work just fine.
7. Choose the 32-bit installation.
In my experience, this version of the app works best with Fire TV devices, but you can try others if you want to experiment.
8. Click Install.
You can also use this screen to review Kodi’s permissions.
9. Customize Kodi to your liking.
You can access Kodi just as you would any other app on the Fire TV. From here, you can share your media libraries, install add-ons and otherwise tweak Kodi to fit your taste. Bear in mind that if you’re using a Fire TV Stick, you’ll probably have to use a remote media server, whereas the Fire TV has a port for USB storage.
