True, that was my goal. I wrote my code so that it would initially
work on J2SE, J2ME, and Android. This forced me to write the business
layer platform-agnostic and just write interfaces that were platform
specific.

>>how did you convert those?
I'm not using LBS so no problem there. However, if I were I would just
put that behind a generic interface.
Services - My application does not require to be running on the
background so I didn't need to convert this.
Android Intent, content provider - I didn't have to use this feature
so I did not have to create an interface for it. IPhone does has
something very similar to this though.
They pass URL's between applications.
What I did have to create interfaces for are the drawing utilities,
Threads, GUI objects, like buttons, text fields, text buttons, touch
and key event handling, etc.
