Class CalendarContract

java.lang.Object
- android.provider.CalendarContract

```
public final class CalendarContract
extends Object
```
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 BaseColumns._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 CalendarContract.CalendarColumns.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:
- CalendarContract.SyncState, which contains free-form data maintained by the sync adapters

  - ACTION_EVENT_REMINDER
```
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.
    
    See Also:
    Constant Field Values
  - ACTION_HANDLE_CUSTOM_EVENT
```
public static final String ACTION_HANDLE_CUSTOM_EVENT
```
    Activity Action: Display the event to the user in the custom app as specified in CalendarContract.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 CalendarContract.EventsColumns.CUSTOM_APP_URI.
    Output: Activity.RESULT_OK if this was handled; otherwise Activity.RESULT_CANCELED
    See Also:
    Constant Field Values
  - EXTRA_CUSTOM_APP_URI
```
public static final String EXTRA_CUSTOM_APP_URI
```
    Intent Extras key: CalendarContract.EventsColumns.CUSTOM_APP_URI for the event in the ACTION_HANDLE_CUSTOM_EVENT intent
    
    See Also:
    Constant Field Values
  - EXTRA_EVENT_BEGIN_TIME
```
public static final String EXTRA_EVENT_BEGIN_TIME
```
    Intent Extras key: The start time of an event or an instance of a recurring event. (milliseconds since epoch)
    
    See Also:
    Constant Field Values
  - EXTRA_EVENT_END_TIME
```
public static final String EXTRA_EVENT_END_TIME
```
    Intent Extras key: The end time of an event or an instance of a recurring event. (milliseconds since epoch)
    
    See Also:
    Constant Field Values
  - EXTRA_EVENT_ALL_DAY
```
public static final String EXTRA_EVENT_ALL_DAY

    Constant Field Values
  - AUTHORITY
```
public static final String AUTHORITY
```
    This authority is used for writing to or querying from the calendar provider. Note: This is set at first run and cannot be changed without breaking apps that access the provider.
    
    See Also:
    Constant Field Values
  - CONTENT_URI
```
public static final Uri CONTENT_URI
```
    The content:// style URL for the top-level calendar authority
  - CALLER_IS_SYNCADAPTER
```
public static final String CALLER_IS_SYNCADAPTER
```
    An optional insert, update or delete URI parameter that allows the caller to specify that it is a sync adapter. The default value is false. If set to true, the modified row is not marked as "dirty" (needs to be synced) and when the provider calls ContentResolver.notifyChange(android.net.Uri, android.database.ContentObserver, boolean) , the third parameter "syncToNetwork" is set to false. Furthermore, if set to true, the caller must also include CalendarContract.SyncColumns.ACCOUNT_NAME and CalendarContract.SyncColumns.ACCOUNT_TYPE as query parameters.
    
    See Also:
    Uri.Builder#appendQueryParameter(java.lang.String, java.lang.String), Constant Field Values
  - ACCOUNT_TYPE_LOCAL
```
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.
