CalendarContract

extends Object
java.lang.Object
   ↳ android.provider.CalendarContract

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:

    <category android:name="android.intent.category.DEFAULT" />

 </intent-filter>
