I was requested to develop an Amazon Fire TV app, but I find difficult to understand the steps required to get on track.
As specified by the Amazon documentation, the previously available Fire TV SDK add-on is now deprecated, and they suggest to just use the Android v17 Leanback Library.
To date, I do not have (yet) a Fire TV, and the official documentation is very poor and rather confused; I'm not able – then – to understand whether "pure" Android TV apps are fully compatible with Fire OS 5, so that developing for the Fire TV is actually the same as developing for a generic Amazon TV (from the SDK, to the virtual testing process). In the case it isn't, what are the different steps I have to take into account?
