I have created an Android TV app that works as expected on my ADT-1. However, I've found it also works on my Nexus 10 and Nexus 4 devices (although it's not really usable on the Nexus 4 because you can't see enough on the screen) if I install it using ADB.
When I publish it on Google Play in beta test mode, I can actually install it on all 3 devices. But the icon only shows up on the ADT-1, and I can only launch it from there. It doesn't show up as an installed app on the other devices, and within Google Play there is no launch option, only Uninstall.
So I either need it to work on tablets, where it actually looks OK, or not allow people to install it except on an Android TV device. However, Google Play actually requires you to upload screenshots of both Android TV and 10 inch tablets. So what am I missing?
