I believe that sqlite is not a fundamentally a java application, but one running in the embedded linux with some android java wrappers around it. As a result, inserting encryption into its file operations would probably have to be handled with a linux kernel module (or at best a userspace filesystem driver), which is not something you can do on a retail phone as root permission is requried.
You might look and see how big sqlite acutally is... perhaps its small enough that you could build your own custom version with encryption and ship that with your application using your own jni or sockets wrapper.
