This data is stored in a number of tables: 50 * </p> 51 * <ul> 52 * <li>The {@link Calendars} table holds the calendar specific information. Each 53 * row in this table contains the details for a single calendar, such as the 54 * name, color, sync info, etc.</li> 55 * <li>The {@link Events} table holds the event specific information. Each row 56 * in this table has the info for a single event. It contains information such 57 * as event title, location, start time, end time, etc. The event can occur 58 * one-time or can recur multiple times. Attendees, reminders, and extended 59 * properties are stored on separate tables and reference the {@link Events#_ID} 60 * to link them with the event.</li> 61 * <li>The {@link Instances} table holds the start and end time for occurrences 62 * of an event. Each row in this table represents a single occurrence. For 63 * one-time events there will be a 1:1 mapping of instances to events. For 64 * recurring events, multiple rows will automatically be generated which 65 * correspond to multiple occurrences of that event.</li> 66 * <li>The {@link Attendees} table holds the event attendee or guest 67 * information. Each row represents a single guest of an event. It specifies the 68 * type of guest they are and their attendance response for the event.</li> 69 * <li>The {@link Reminders} table holds the alert/notification data. Each row 70 * represents a single alert for an event. An event can have multiple reminders. 71 * The number of reminders per event is specified in 72 * {@link Calendars#MAX_REMINDERS} which is set by the Sync Adapter that owns 73 * the given calendar. Reminders are specified in minutes before the event and 74 * have a type.</li> 75 * <li>The {@link ExtendedProperties} table holds opaque data fields used by the 76 * sync adapter. The provider takes no action with items in this table except to 77 * delete them when their related events are deleted.</li> 78 * </ul> 79 * <p> 80 * Other tables include: 81 * </p> 82 * <ul> 83 * <li> 84 * {@link SyncState}, which contains free-form data maintained by the sync 85 * adapters</li> 86 * </ul> 87 * 88 */ 89public final class CalendarContract { 90 private static final String TAG = "Calendar"; 91 92 /** 93 * Broadcast Action: This is the intent that gets fired when an alarm 94 * notification needs to be posted for a reminder. 95 * 96 */ 97 @SdkConstant(SdkConstantType.ACTIVITY_INTENT_ACTION) 98 public static final String ACTION_EVENT_REMINDER = "android.intent.action.EVENT_REMINDER"; 99 100 /** 101 * Intent Extras key: The start time of an event or an instance of a 102 * recurring event.
