While the Fire Phone may not have done well, all the Amazon Fire products are Android based. This includes the Fire Phone, Fire Tablets, and Fire TV.
They are based on AOSP, but Amazon is expressly forbidden from using the Android name, and it can't use the Play store, so it's not really in the Android (TM) market.

Yes, I do know who you are -- in fact, we have met -- but Google should not be using Android™ if it's not trademarked ;-)
