ContactsContract

Kotlin |Java

public final class ContactsContract
extends Object

java.lang.Object
↳	android.provider.ContactsContract

The contract between the contacts provider and applications. Contains definitions for the supported URIs and columns. These APIs supersede Contacts.

Overview

ContactsContract defines an extensible database of contact-related information. Contact information is stored in a three-tier data model:

A row in the Data table can store any kind of personal data, such as a phone number or email addresses. The set of data kinds that can be stored in this table is open-ended. There is a predefined set of common kinds, but any application can add its own data kinds.
A row in the RawContacts table represents a set of data describing a person and associated with a single account (for example, one of the user's Gmail accounts).
A row in the Contacts table represents an aggregate of one or more RawContacts presumably describing the same person. When data in or associated with the RawContacts table is changed, the affected aggregate contacts are updated as necessary.

Other tables include:

Groups, which contains information about raw contact groups such as Gmail contact groups. The current API does not support the notion of groups spanning multiple accounts.
StatusUpdates, which contains social status updates including IM availability.
AggregationExceptions, which is used for manual aggregation and disaggregation of raw contacts
Settings, which contains visibility and sync settings for accounts and groups.
SyncState, which contains free-form data maintained on behalf of sync adapters
PhoneLookup, which is used for quick caller-ID lookup

Constants

AUTHORITY

Added in API level 5

public static final String AUTHORITY

The authority for the contacts provider

Constant Value: "com.android.contacts"

CALLER_IS_SYNCADAPTER

Added in API level 5

public static final String CALLER_IS_SYNCADAPTER

An optional URI parameter for insert, update, or delete queries that allows the caller to specify that it is a sync adapter. The default value is false. If true RawContacts#DIRTY is not automatically set and the "syncToNetwork" parameter is set to false when calling ContentResolver.notifyChange(android.net.Uri, android.database.ContentObserver, boolean). This prevents an unnecessary extra synchronization, see the discussion of the delete operation in RawContacts.

Constant Value: "caller_is_syncadapter"

DEFERRED_SNIPPETING

Added in API level 21

public static final String DEFERRED_SNIPPETING

A key to a boolean in the "extras" bundle of the cursor. The boolean indicates that the provider did not create a snippet and that the client asking for the snippet should do it (true means the snippeting was deferred to the client).

See also:

ContactsContract.SearchSnippets

Constant Value: "deferred_snippeting"

DEFERRED_SNIPPETING_QUERY

Added in API level 21

public static final String DEFERRED_SNIPPETING_QUERY

Key to retrieve the original deferred snippeting from the cursor on the client side.

See also:

Constant Value: "deferred_snippeting_query"

DIRECTORY_PARAM_KEY

Added in API level 11

public static final String DIRECTORY_PARAM_KEY

Query parameter that should be used by the client to access a specific Directory. The parameter value should be the _ID of the corresponding directory, e.g. content://com.android.contacts/data/emails/filter/acme?directory=3

Constant Value: "directory"

LIMIT_PARAM_KEY

Added in API level 11

public static final String LIMIT_PARAM_KEY

A query parameter that limits the number of results returned for supported URIs. The parameter value should be an integer.

This parameter is not supported by all URIs. Supported URIs include, but not limited to, Contacts#CONTENT_URI, RawContacts#CONTENT_URI, Data#CONTENT_URI, ContactsContract.CommonDataKinds.Phone.CONTENT_URI, ContactsContract.CommonDataKinds.Callable.CONTENT_URI, ContactsContract.CommonDataKinds.Email.CONTENT_URI, ContactsContract.CommonDataKinds.Contactables.CONTENT_URI,

In order to limit the number of rows returned by a non-supported URI, you can implement a CursorWrapper and override the CursorWrapper#getCount() methods.

Constant Value: "limit"

PRIMARY_ACCOUNT_NAME

Added in API level 14

public static final String PRIMARY_ACCOUNT_NAME

A query parameter specifing a primary account. This parameter should be used with PRIMARY_ACCOUNT_TYPE. The contacts provider handling a query may rely on this information to optimize its query results. For example, in an email composition screen, its implementation can specify an account when obtaining possible recipients, letting the provider know which account is selected during the composition. The provider may use the "primary account" information to optimize the search result.

Constant Value: "name_for_primary_account"

PRIMARY_ACCOUNT_TYPE

Added in API level 14

public static final String PRIMARY_ACCOUNT_TYPE

A query parameter specifing a primary account. This parameter should be used with PRIMARY_ACCOUNT_NAME. See the doc in PRIMARY_ACCOUNT_NAME.

Constant Value: "type_for_primary_account"

REMOVE_DUPLICATE_ENTRIES

Added in API level 21

public static final String REMOVE_DUPLICATE_ENTRIES

A boolean parameter for Phone.CONTENT_URI, Email.CONTENT_URI, and StructuredPostal.CONTENT_URI. This enables a content provider to remove duplicate entries in results.

Constant Value: "remove_duplicate_entries"

STREQUENT_PHONE_ONLY

Added in API level 21

public static final String STREQUENT_PHONE_ONLY

A boolean parameter for Contacts#CONTENT_STREQUENT_URI and Contacts#CONTENT_STREQUENT_FILTER_URI, which requires the ContactsProvider to return only phone-related results.

Constant Value: "strequent_phone_only"

Fields

AUTHORITY_URI

Added in API level 5

public static final Uri AUTHORITY_URI

A content:// style uri to the authority for the contacts provider

Public constructors
