Nope, won't run on the Galaxy Tab. FileMaker Go is only for the iPad, iPhone and iPod Touch (Apple iOS devices).
Additionally, the Galaxy Tab uses an operating system (Android) that even its maker (Google) has said is not ready for prime-time on tablet devices. And it sounds like Google may not ever recommend Android for tablets, but rather suggest their Chrome OS instead. I would certainly not consider using an Android tablet until this has all settled out.
For the info.
