Android TV

Hi,
I use Audiorelay with my Nvidia shield and it works perfectly!
The point is that the app is not recognized as an Android TV app, so it can’t be downloaded through the play store and I can’t purchased it as well.
So is it possible to make the app “TV” compatible?
And second point: Is it possible to connect to the last server automatically? So when I switch off/on the PC I don’t have to open the app on the TV!
Anyway thanks for this wonderfull app!
