Of course it will. Nothing that is offered on the Fire is Fire exclusive. There are a couple of games but that is just because it is locked out of the wider android marketplace where you could already get the games in question. All of the books, magazines, comics, etc. just works through the kindle app that has been on android for years.
I guess that the amazon streaming video is exclusive to the fire but there is still a pleathora of options out there from non-kindle android devices.
