| This sample demonstrates using SyncAdapter to fetch background data for an app that |
| doesn\'t require a user-visible account type or 2-way synchronization. |
| |
| \n\nThis sample periodically downloads the feed from the Android Developer Blog and |
| caches the data in a content provider. At runtime, the cached feed data is displayed |
| inside a ListView. |

| This sample demonstrates using SyncAdapter to fetch background data |
| for an app. SyncAdapters can be used to execute your data transfer |
| code at configurable intervals, while efficiently using battery and |
| other system resources. |
| |
| This sample implements all the required elements of a sync adapter. |
| - Creates a sync adapter class. |
| - Creates a bound Service which the OS uses to initiate a sync. |
| - Defines the sync adapter properties in an XML resource file. |
| - Declares the bound Service in the app manifest. |
| |
