Operations

All operations can be done * either as an app or as a sync adapter. To perform an operation as a sync * adapter {@link #CALLER_IS_SYNCADAPTER} should be set to true and * {@link #ACCOUNT_NAME} and {@link #ACCOUNT_TYPE} must be set in the Uri * parameters. See * {@link Uri.Builder#appendQueryParameter(java.lang.String, java.lang.String)} * for details on adding parameters. Sync adapters have write access to more * columns but are restricted to a single account at a time. Calendars are * designed to be primarily managed by a sync adapter and inserting new * calendars should be done as a sync adapter. For the most part, apps * should only update calendars (such as changing the color or display * name). If a local calendar is required an app can do so by inserting as a * sync adapter and using an {@link #ACCOUNT_TYPE} of * {@link #ACCOUNT_TYPE_LOCAL} . *
*
Insert
*
When inserting a new calendar the following fields must be included: * * The following fields are not required when inserting a Calendar but are * generally a good idea to include: * *
Update
*
To perform an update on a calendar the {@link #_ID} of the calendar * should be provided either as an appended id to the Uri ( * {@link ContentUris#withAppendedId}) or as the first selection item--the * selection should start with "_id=?" and the first selectionArg should be * the _id of the calendar. Calendars may also be updated using a selection * without the id. In general, the {@link #ACCOUNT_NAME} and * {@link #ACCOUNT_TYPE} should not be changed after a calendar is created * as this can cause issues for sync adapters. *
Delete
*
Calendars can be deleted either by the {@link #_ID} as an appended id * on the Uri or using any standard selection. Deleting a calendar should * generally be handled by a sync adapter as it will remove the calendar * from the database and all associated data (aka events).
*
Query
*
Querying the Calendars table will get you all information about a set * of calendars. There will be one row returned for each calendar that * matches the query selection, or at most a single row if the {@link #_ID} * is appended to the Uri.
*

Operations

All operations can be done either * as an app or as a sync adapter. To perform an operation as a sync adapter * {@link #CALLER_IS_SYNCADAPTER} should be set to true and * {@link #ACCOUNT_NAME} and {@link #ACCOUNT_TYPE} must be set in the Uri * parameters. See * {@link Uri.Builder#appendQueryParameter(java.lang.String, java.lang.String)} * for details on adding parameters. Sync adapters have write access to more * columns but are restricted to a single account at a time. *
*
Insert
*
When inserting a new event the following fields must be included: * * There are also further requirements when inserting or updating an event. * See the section on Writing to Events.
*
Update
*
To perform an update of an Event the {@link Events#_ID} of the event * should be provided either as an appended id to the Uri ( * {@link ContentUris#withAppendedId}) or as the first selection item--the * selection should start with "_id=?" and the first selectionArg should be * the _id of the event. Updates may also be done using a selection and no * id. Updating an event must respect the same rules as inserting and is * further restricted in the fields that can be written. See the section on * Writing to Events.
*
Delete
*
Events can be deleted either by the {@link Events#_ID} as an appended * id on the Uri or using any standard selection. If an appended id is used * a selection is not allowed. There are two versions of delete: as an app * and as a sync adapter. An app delete will set the deleted column on an * event and remove all instances of that event. A sync adapter delete will * remove the event from the database and all associated data.
*
Query
*
Querying the Events table will get you all information about a set of * events except their reminders, attendees, and extended properties. There * will be one row returned for each event that matches the query selection, * or at most a single row if the {@link Events#_ID} is appended to the Uri. * Recurring events will only return a single row regardless of the number * of times that event repeats.
*
*
