I have bought a few apps for my phone that I would like to side load onto my Shield TV (One example is the game Pandemic, although I don't know how will it will work on Android TV).

But how do I get access to the apk to install it? I know there are a lot of sites to get apks for free apps, but what's the best way to get access to apks for paid apps that I already own? I tried sending it to my shield from a browser but it says it isn't compatible...
