-<p>This sample demonstrates how to implement a sync adapter to fetch background
-data for an app that doesn't require a user-visible account type or two-way
-synchronization.</p>
-<p>The sample periodically downloads the feed from the <a href="http://android-developers.blogspot.com/">Android Developers Blog</a> and caches the data in a content provider. At runtime, the cached feed data is
-displayed inside a {@link android.widget.ListView}.</p>
