RESTful Android is an implementation of the RESTful Android app architecture as described in Developing Android REST client applications, a talk by Virgil Dobjanschi at Google I/O 2010.
Displays the current state of a resource, or set of resources, by observing the Content Provider that holds the resource, typically via a CursorAdapter. CRUD requests for a resource are executed asynchronously using the ServiceHelper. The activity can listen for the result of the requests, which are broadcast by the ServiceHelper, and display any indicators on the UI. Any update of the actual resource is retrieved via the ContentProvider.
Exposes an asynchronous API for the front-end application that provides access to resources. Translates a resource request from the UI layer into service invocation. Immediately returns a unique request id to a caller, and later broadcasts the result of the request, once completed by the service layer. Maintains the state of all pending requests.
Stateless process that accepts resource requests from the application layer, and invokes the correct processor for that resource in a background thread. Returns the result of the request along with original intent in an asynchronous callback.
Maintain the state of a resource and any transactions for that resource using a Content Provider. Knows how to execute rest operations for a resource. Returns the result of the transaction.
Understands the semantics of the remote api needed for the resource and handles the actual http requests. Rest Methods are blocking and return the result of the request and optionally a raw representation of the resource.

This book has a complete chapter (13. Exploring Content Providers) dedicated to 'Option B: Use the ContentProvider API' from Virgil's Google I/O talk:We are not the only ones who see the benefits of this approach. At the Google I/O conference in May 2010, Virgil Dobjanschi of Google presented a talk that outlined the following three patterns for using content providers to integrate RESTful web services into Android applications...
In this chapter, we’ll explore the second pattern in detail with our second Finch video example; this strategy will yield a number of important benefits for your applications. Due to the elegance with which this approach integrates network operations into Android MVC, we’ve given it the moniker “Network MVC.”
A future edition of Programming Android may address the other two approaches, as well as document more details of this Google presentation. After you finish reading this chapter, we suggest that you view Google’s talk.

This project contains two branches:
- master
- catpictures
The master branch is the main development branch and uses the Twitter API for content. Contributions to the project should be made here.
The catpictures branch is a simple, no-fluff version for use with the Developing an Android RESTful Client App presentation at Mobile March and Gluecon. This one uses the catpictures subreddit for its content.
This branch is currently ahead of master in terms of features and maturity. Following the Mobile March presentation, changes will be brought back to master.
