-/**
- * Content providers are one of the primary building blocks of Android applications, providing
- * content to applications. They encapsulate data and provide it to applications through the single
- * {@link ContentResolver} interface. A content provider is only required if you need to share
- * data between multiple applications. For example, the contacts data is used by multiple
- * applications and must be stored in a content provider. If you don't need to share data amongst
- * multiple applications you can use a database directly via
- * {@link android.database.sqlite.SQLiteDatabase}.
- *
- * <p>For more information, read <a href="{@docRoot}guide/topics/providers/content-providers.html">Content
- * Providers</a>.</p>
- *
- * <p>When a request is made via
- * a {@link ContentResolver} the system inspects the authority of the given URI and passes the
- * request to the content provider registered with the authority. The content provider can interpret
- * the rest of the URI however it wants. The {@link UriMatcher} class is helpful for parsing
- * URIs.</p>
- *
- * <p>The primary methods that need to be implemented are:
- * <ul>
- *   <li>{@link #query} which returns data to the caller</li>
- *   <li>{@link #insert} which inserts new data into the content provider</li>
- *   <li>{@link #update} which updates existing data in the content provider</li>
- *   <li>{@link #delete} which deletes data from the content provider</li>
- *   <li>{@link #getType} which returns the MIME type of data in the content provider</li>
- * </ul></p>
- *
- * <p>This class takes care of cross process calls so subclasses don't have to worry about which
- * process a request is coming from.</p>
