| Class | Description | 
|---|---|
| CachedData | Cached data class for use with the cached data service | 
| CachedDataService | Simple service that allows downloading and caching data locally. | 
| ImageDownloadService | Deprecated this class uses an unconventional storage mechanism and has many issues, we recommend
 replacing it with the simpler and more powerful URLImage or Util.dowloadFileTo* calls. | 
| RSSService | Simple RSS read and parse request, to handle errors just subclass this and override
 parsingError. | 
| TwitterRESTService | Calls to the Twitter REST API can be performed via this class although currently
 support for authentication isn't implemented due to the transition to oAuth instead
 of basic authentication. |
