Android TV has an advantage over Fire TV here: the Google Play Store is built in, so installing a compatible IPTV player is usually a normal app-store install.
Step 1: Install a compatible IPTV player
From the Android TV home screen, open the Google Play Store app, search for a compatible IPTV player, and install it.
Step 2: If it’s not on the Play Store
Some players aren’t listed. In that case, install Downloader and use the XTREME HD IPTV code 6768998 the same way you would on Fire TV.
Step 3: Add your login
Open the installed app, choose to add a new playlist or user, and enter the username, password and server URL you were sent after ordering.
Step 4: Load the channel list
Save and give the app a moment to load channels and the EPG, then open Live TV.
