The goal is to cache some responses from web service.
I am using Spring for Android framework - http://www.springsource.org/spring-android#documentation to communicate with restful service. As I know I can add caching into application using some module from the common Spring Framework ( http://viralpatel.net/blogs/cache-support-spring-3-1-m1/ ). Am I right that it is not possible to do using just spring-for-android? What is the solution then?
*I don't have any experience in a common Spring.
So, it was easier to use extra database for caching purposes. I have used these columns: expiration date, request url, request object (hash), response object (serialized).
I have "asked" for cache just before request was sent to server. It was enough to fulfill my goals, if you need extra features probably you need additional columns.
I am a contributor to RoboSpice. This library offers a nice asynchronous model for network request with caching. We also have a Spring Android Module that you could be interested in.
