Summary

This chapter looked at data strategies on Android. By using these technologies, developers can build native applications that run when a network connection is unavailable. You've learned how to do the following:

• Set up a local database in SQLite on Android
• Run commands against the SQLite database on Android
• Work with SOAP-based web services on Android
• Work with REST-based web services on Android

When they add the ability to call web services, Android developers and their applications can integrate with central data stores. This allows an application's users to interact with other users. For example, Twitter users can use Android to interact with other Twitter users without ever having to go to Twitter.com. Using Android, you can create applications that provide more features for users and that are more resistant to problems when connecting to the Internet and its data sources.
