The TutList application that we've been working with has a pretty big flaw right now: the article data is not "live", but static content. In this tutorial, you take several more steps towards a flexible and expandable solution by modifying the application to act as a data-backed content provider.

The Android framework uses a concept called content providers to enable applications to share and use data across the platform. Typically, a provider is backed by a SQLite database where the underlying data is stored. The current state of the TutList application is such that it gets the data for the ListView from static string arrays in the resources. In this tutorial, we'll remove those fixed data resources and build a flexible database-driven content provider in their place. You'll see that the user interface code won't change much. The back-end, however, will get more complex. The advantage here is that when we finally switch the application over to retrieving live data from the Internet, we'll have a place to store and manage it easily.
