Yeah but I want to get away from using a browser and html/css. I haven't had great success in getting a full screen webpage to display properly (not just left to right, but constrained top to bottom as well) on various TV sizes. So I wanted to develop something more like an app since it seems that those work just fine on various TVs. Thinking of things like say a ROKU interface or something like that. I was just wondering if there were different methods/practices that were used in developing a full screen TV type interface as opposed to developing for a browser window. Where elements are placed around the screen, fixed and constrained to the viewable area of the TV.
There are TVs that run Android, and an Android TV api. If you're used to writing apps, that would probably be an easy-ish platform to start on.
