I think you're limiting this app by calling it 'for Fire TV'. It's a great clone of the Nougat launcher for any device that can't install the real version.Hi! It's great to see someone continuing this work. I obviously haven't had time to work on this and I don't use the AFTV platform as much as I used to. I'll reach out via PM in a bit and we can potentially figure out updating the posts to direct to your work.
In my case, Sony has taken my 2015 TV and with a firmware update in the past month, shoved that awful Oreo launcher into it. They then added an un-modifyiable dummy app with the same name as the old launcher to prevent any from going back.
This works great for me. Perhaps just call this Leanback Launcher for Android TVs (which seems redundant). But it is great to have and should work with any android device.
Btw, I don't know if you read the last few posts, but the settings change from v1.10 to v1.11 removes at least one option that I need to have access to.
