 *     <tr><th>Column Name</th> <th>Description</th> </tr>
 *     </thead>
 *

 * 
 * <tr><th>{@link SearchManager#SUGGEST_COLUMN_ICON_1}</th>
 *     <td>The application's icon resource id, prepended by its package name and
 *         separated by a colon, e.g., "com.android.alarmclock:2130837524". The
 *         package name is required for an activity interpreting this value to
 *         be able to correctly access the icon drawable, for example, in an override of
 *         {@link SimpleCursorAdapter#setViewImage(android.widget.ImageView, String)}.</td>

 *            that all providers provide either both or neither of
 *            {@link SearchManager#SUGGEST_COLUMN_ICON_1} and
 *            {@link SearchManager#SUGGEST_COLUMN_ICON_2}.</td>
