I asked the very same question a couple of weeks ago ;-)
Thanks Gary for information, I saw your post
The only real option at the moment is to use a service like our Citrix XenApp hosted service, which will run on any platform. However, you do need WIFI or 3G to be able to do this.
All the best
Or you can develop your solution on CWP like a lot of developers have been doing for mobile apps for years already.
Filemaker has made it very clear, however, that iOS is the only platform they're really interested in for FM Go as an application. But I think we're overdue for some web publishing overhauls that will improve the viability of other mobile platforms.
