Here's the fundamental issue with Android: Gnucash for Android (GFA) is a separate application from Gnucash. In order to directly access a Gnucash database, GFA would need the rather ungainly library code written in C with GLib contained in Gnucash, which it doesn't.
As for the web-backed service, well, that's kind of interesting. We were discussing that a couple of weeks ago. There are at present some known or suspected holes in our SQL implementation: Most things work, but there are some reported bugs that indicate not everything does. We're working on better test coverage to find the holes so that we can plug them. The next problem is that Gnucash isn't a database application, it just uses the database as a store. Most things it writes immediately and in reasonable transactions, but a few things aren't set up correctly and it needs to delete and re-write the whole database. That's going to kill performance over the net. We do intend to fix that, but lack of good and complete tests lies between here and there.
