Android Restful Stack

Below are the three external libraries we are using for making restful call to our RoR backend and parse it to models and finally we are using the pulltorefresh library for listviews.

For async calls -
https://github.com/AsyncHttpClient/async-http-client

For parsing json to models -
http://code.google.com/p/google-gson/

For pulltorefresh on UI -
