I have a USB HDMI capture video adaptor that I use in my android tv box and all I want is a simple android tv app that does nothing but show the stream of the connected hdmi device when the app opens. Can anyone guide me on how to build such an app? There are apps on the play store that comes close, but nothing that is clean and simple as the app I am looking for. Anyone who can help me build this? I haven't done coding in a long time but I can manage my way around with some guidance.
