Prevent unauthorized APK installs on Amazon & Nook devices?

Hi all,

I’m following develephant’s tutorial (which is great, btw) on using Google Play licensing in an effort to prevent/minimize piracy of my app on Google Play.

Is there something similar we can do for the other mainstream Android stores ( Amazon / Nook  ) ?

Also, how do people install Ouya apps?

As always, thanks for any help!
