Before you start
This tutorial introduces XML handling in Android. To build the sample application in this tutorial, the Android SDK must be installed and running on your development computer. Building applications for Android in Eclipse is recommended but not required for this tutorial. Mobile development experience is helpful, but Java ™ programming skills are necessary for Android applications and will be useful for this tutorial.
Why do you care about an RSS reader for Android? And where XML fits into the picture? First, Android is a platform that is rapidly gaining mindshare in the mobile market. Even before the consumer devices equipped with Android is has thousands of developers are jumping into the mobile market, hoping to be ready for the highly anticipated introduction of Android-equipped devices in the near future.

If interested, you can drill down and get “the rest of the story” as Paul Harvey radio show host would say. This tutorial shows the main aspects of XML data manipulation in building Android RSS reader.
This tutorial is organized into the following sections:
