Is there anyone who used this design pattern? the Virgil Dobjanschi model, it's a restful webservice pattern for android?

I haven't, but here's an interesting post about it: http://www.codeproject.com/Articles/429997/Sample-Implementation-of-Virgil-Dobjanschis-Rest-p

What i learned from the experience on trying to implement the Dobjanschi Model, is that not everything is written in stone and he only give you the overview of what to do this might changed from app to app but the formula is: Follow this ideas + Add your own = Happy Android application The model on some apps may vary from requirement some might not need the Account for the SyncAdapter other might use C2DM, this one that i worked recently might help someone.....

anyway, I have used the second pattern which it uses the content provider api, and anyone who was confused at the beginning as i was, I recommend to search for a library called robospice , it's really a great library, which it uses spring android, also if anyone is confused on how to make the database, anyone who knew hibernate , these libraries could help (ormlite,greenDao)
