Android TV (Android version 8.0+)Kodi v18 (Leia)To add more channels you simple need to create Playlists. The easiest way to do this is to use the built in Smart Playlist feature. https://kodi.wiki/view/Playlists Go toThe first thing that you'll need to do is to create an".There are many way to create a playlist rule, by title, year, genre, path, sets, etc. For this example I'm just using "Title" and adding each file manually.If you add the files by title you don't need to add a new rule for each title, you can just click "Browse" then select each title you want to add, each highlighted file will be added.Once you have added every file you want in your playlist, click OK, then OK again in the "rule" window. Now you can set limits and how your playlist will be ordered.Once you have everything as you want it click OK to create your playlist. The on-screen keyboard will now display and you will be able to name your Playlist.Now you can go back to the launcher and you should be able to see that your new channel as been added.Enable your channel and you should now see it on the launcher.NOTE: Depending on how many files you have added to your playlist it may take a few minutes before the thumbs get generated after you add your channel.If your Playlist is static (one that does not ever change) the data for the "Channel" will also never change. However, if you create a dynamic Playlist by either Rule or by Order state (i.e. Random ordering) the "Channel" will periodically update to reflect those changes.Channels are limited to only 20 thumbs.NOTE 2: The new launcher can be a little flaky about adding channels or populating the data. This is not just limited to Kodi. If you have issues, first make sure that there's nothing wrong with your playlist. If it's OK, try removing the channel and then add it again. You can also try doing a reboot,If all else fails, try clearing the data for the launcher.. There doesn't seem to be a magic bullet to make channels or the channels data to appear, you may have to try different things or a combination of different things, but it will eventually work.
