Soon :How to connect to Firebird using #Android #.Net provider via #MonoDroid
You can do this (in theory) using Firebird .Net provider and Mono via MonoDroid (private preview and seems that you need to pay for it later ) or with the opensource project androidmono
After MonoTouch on Iphone / Ipad now you can connect to a firebird database using .net provider and mono
I saw it on this tweet and Jiri answered that he will try it if he gets a MonoDroid sdk
