Class Overview

The contract between the calendar provider and applications. Contains definitions for the supported URIs and data columns.

Overview

CalendarContract defines the data model of calendar and event related information. This data is stored in a number of tables:

  • The CalendarContract.Calendars table holds the calendar specific information. Each row in this table contains the details for a single calendar, such as the name, color, sync info, etc.
  • The CalendarContract.Events table holds the event specific information. Each row in this table has the info for a single event. It contains information such as event title, location, start time, end time, etc. The event can occur one-time or can recur multiple times. Attendees, reminders, and extended properties are stored on separate tables and reference the _ID to link them with the event.
  • The CalendarContract.Instances table holds the start and end time for occurrences of an event. Each row in this table represents a single occurrence. For one-time events there will be a 1:1 mapping of instances to events. For recurring events, multiple rows will automatically be generated which correspond to multiple occurrences of that event.
  • The CalendarContract.Attendees table holds the event attendee or guest information. Each row represents a single guest of an event. It specifies the type of guest they are and their attendance response for the event.
  • The CalendarContract.Reminders table holds the alert/notification data. Each row represents a single alert for an event. An event can have multiple reminders. The number of reminders per event is specified in MAX_REMINDERS which is set by the Sync Adapter that owns the given calendar. Reminders are specified in minutes before the event and have a type.
  • The CalendarContract.ExtendedProperties table holds opaque data fields used by the sync adapter. The provider takes no action with items in this table except to delete them when their related events are deleted.

Other tables include:

Constants

public static final String ACCOUNT_TYPE_LOCAL

Added in API level 14

public static final String ACTION_EVENT_REMINDER

public static final String ACTION_HANDLE_CUSTOM_EVENT

Added in API level 16

Activity Action: Display the event to the user in the custom app as specified in CUSTOM_APP_PACKAGE. The custom app will be started via startActivityForResult(Intent, int) and it should call setResult(int) with RESULT_OK or RESULT_CANCELED to acknowledge whether the action was handled or not. The custom app should have an intent filter like the following:

 <intent-filter>
    <action android:name="android.provider.calendar.action.HANDLE_CUSTOM_EVENT" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="vnd.android.cursor.item/event" />
 </intent-filter>

Input: getData() has the event URI. The extra EXTRA_EVENT_BEGIN_TIME has the start time of the instance. The extra EXTRA_CUSTOM_APP_URI will have the CUSTOM_APP_URI.

Output: RESULT_OK if this was handled; otherwise RESULT_CANCELED.

Constant Value: "android.provider.calendar.action.HANDLE_CUSTOM_EVENT"
