CalendarContract

public final class CalendarContract
extends Object

java.lang.Object
   ↳ android.provider.CalendarContract


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 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 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 Events#_ID to link them with the event.
  • The 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 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 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 Calendars#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 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:

  • SyncState, which contains free-form data maintained by the sync adapters

Inherited methods

Constants

ACCOUNT_TYPE_LOCAL

Added in API level 14
public static final String ACCOUNT_TYPE_LOCAL

A special account type for calendars not associated with any account. Normally calendars that do not match an account on the device will be removed. Setting the account_type on a calendar to this will prevent it from being wiped if it does not match an existing account.

Constant Value: "LOCAL"

ACTION_EVENT_REMINDER

Added in API level 14
public static final String ACTION_EVENT_REMINDER

Broadcast Action: This is the intent that gets fired when an alarm notification needs to be posted for a reminder.

Constant Value: "android.intent.action.EVENT_REMINDER"

ACTION_HANDLE_CUSTOM_EVENT

Added in API level 16
public static final String ACTION_HANDLE_CUSTOM_EVENT

Activity Action: Display the event to the user in the custom app as specified in EventsColumns#CUSTOM_APP_PACKAGE. The custom app will be started via Activity#startActivityForResult(Intent, int) and it should call Activity#setResult(int) with Activity#RESULT_OK or Activity#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: Intent#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 EventsColumns#CUSTOM_APP_URI.

Output: Activity#RESULT_OK if this was handled; otherwise Activity#RESULT_CANCELED.

startViewCalendarEventInManagedProfile

Added in API level 29
public static boolean startViewCalendarEventInManagedProfile (Context context,

                long startMs, 
                long endMs, 
                boolean allDay, 
                int flags)

Starts an activity to view calendar events in the managed profile. When this API is called, the system will attempt to start an activity in the managed profile with an intent targeting the same caller package. The intent will have its action set to CalendarContract#ACTION_VIEW_MANAGED_PROFILE_CALENDAR_EVENT and contain extras corresponding to the API's arguments. A calendar app intending to support cross-profile events viewing should handle this intent, parse the arguments and show the appropriate UI.

Parameters
context Context: the context. This value cannot be null.

eventId long: the id of the event to be viewed. Will be put into EXTRA_EVENT_ID field of the intent.

startMs long: the start time of the event in milliseconds since epoch. Will be put into EXTRA_EVENT_BEGIN_TIME field of the intent.

endMs long: the end time of the event in milliseconds since epoch. Will be put into EXTRA_EVENT_END_TIME field of the intent.

allDay boolean: if the event is an all-day event. Will be put into EXTRA_EVENT_ALL_DAY field of the intent.

flags int: flags to be set on the intent via Intent#setFlags

Returns
boolean true if the activity is started successfully. false otherwise.
