ContactsContract.Contacts

CONTENT_ITEM_TYPE

public static final String CONTENT_ITEM_TYPE

The MIME type of a CONTENT_URI subdirectory of a single person.

Constant Value: "vnd.android.cursor.item/contact"

CONTENT_TYPE

public static final String CONTENT_TYPE

The MIME type of CONTENT_URI providing a directory of people.

Constant Value: "vnd.android.cursor.dir/contact"

CONTENT_VCARD_TYPE

public static final String CONTENT_VCARD_TYPE

The MIME type of a CONTENT_URI subdirectory of a single person.

EXTRA_ADDRESS_BOOK_INDEX

public static final String EXTRA_ADDRESS_BOOK_INDEX

Add this query parameter to a URI to get back row counts grouped by the address book index as cursor extras. For most languages it is the first letter of the sort key. This parameter does not affect the main content of the cursor.

 Example:

 import android.provider.ContactsContract.Contacts;

 Uri uri = Contacts.CONTENT_URI.buildUpon()
          .appendQueryParameter(Contacts.EXTRA_ADDRESS_BOOK_INDEX, "true")
          .build();
 Cursor cursor = getContentResolver().query(uri,
          new String[] {Contacts.DISPLAY_NAME},
          null, null, null);
 Bundle bundle = cursor.getExtras();
 if (bundle.containsKey(Contacts.EXTRA_ADDRESS_BOOK_INDEX_TITLES) &&
         bundle.containsKey(Contacts.EXTRA_ADDRESS_BOOK_INDEX_COUNTS)) {
     String sections[] =
             bundle.getStringArray(Contacts.EXTRA_ADDRESS_BOOK_INDEX_TITLES);
     int counts[] = bundle.getIntArray(Contacts.EXTRA_ADDRESS_BOOK_INDEX_COUNTS);
 }
 

Constant Value: "android.provider.extra.ADDRESS_BOOK_INDEX"

EXTRA_ADDRESS_BOOK_INDEX_COUNTS

public static final String EXTRA_ADDRESS_BOOK_INDEX_COUNTS

The array of group counts for the corresponding group. Contains the same number of elements as the EXTRA_ADDRESS_BOOK_INDEX_TITLES array.

TYPE: int[]

Constant Value: "android.provider.extra.ADDRESS_BOOK_INDEX_COUNTS"

EXTRA_ADDRESS_BOOK_INDEX_TITLES

public static final String EXTRA_ADDRESS_BOOK_INDEX_TITLES

The array of address book index titles, which are returned in the same order as the data in the cursor.

TYPE: String[]

Constant Value: "android.provider.extra.ADDRESS_BOOK_INDEX_TITLES"

QUERY_PARAMETER_VCARD_NO_PHOTO

public static final String QUERY_PARAMETER_VCARD_NO_PHOTO

Boolean parameter that may be used with CONTENT_VCARD_URI and CONTENT_MULTI_VCARD_URI to indicate that the returned vcard should not contain a photo. This is useful for obtaining a space efficient vcard.

Constant Value: "no_photo"

CONTENT_FILTER_URI

public static final Uri CONTENT_FILTER_URI

The content:// style URI used for "type-to-filter" functionality on the CONTENT_URI URI. The filter string will be used to match various parts of the contact name. The filter argument should be passed as an additional path segment after this URI.

CONTENT_FREQUENT_URI

public static final Uri CONTENT_FREQUENT_URI

This field was deprecated in API level 29.
Frequent contacts are no longer supported as of Android version Build.VERSION_CODES.Q. This URI always returns an empty cursor.

Caution: If you publish your app to the Google Play Store, this field doesn't sort results based on contacts frequency. For more information, see the Contacts Provider page.

The content:// style URI for showing a list of frequently contacted people.

CONTENT_GROUP_URI

public static final Uri CONTENT_GROUP_URI

CONTENT_LOOKUP_URI

public static final Uri CONTENT_LOOKUP_URI

A content:// style URI for this table that should be used to create shortcuts or otherwise create long-term links to contacts. This URI should always be followed by a "/" and the contact's ContactsContract.ContactsColumns.LOOKUP_KEY. It can optionally also have a "/" and last known contact ID appended after that. This "complete" format is an important optimization and is highly recommended.

As long as the contact's row ID remains the same, this URI is equivalent to CONTENT_URI. If the contact's row ID changes as a result of a sync or aggregation, this URI will look up the contact using indirect information (sync IDs or constituent raw contacts).

Lookup key should be appended unencoded - it is stored in the encoded form, ready for use in a URI.

CONTENT_MULTI_VCARD_URI

public static final Uri CONTENT_MULTI_VCARD_URI

Base Uri for referencing multiple Contacts entry, created by appending ContactsContract.ContactsColumns.LOOKUP_KEY using Uri#withAppendedPath(Uri, String). The lookup keys have to be joined with the colon (":") separator, and the resulting string encoded. Provides OpenableColumns columns when queried, or returns the referenced contact formatted as a vCard when opened through ContentResolver#openAssetFileDescriptor(Uri, String).

Usage example:

The following code snippet creates a multi-vcard URI that references all the contacts in a user's database.

 public Uri getAllContactsVcardUri() {
     Cursor cursor = getActivity().getContentResolver().query(Contacts.CONTENT_URI,
         new String[] {Contacts.LOOKUP_KEY}, null, null, null);
     if (cursor == null) {
         return null;
     }
     try {
         StringBuilder uriListBuilder = new StringBuilder();
         int index = 0;
         while (cursor.moveToNext()) {
             if (index != 0) uriListBuilder.append(':');
             uriListBuilder.append(cursor.getString(0));
             index++;
         }
         return Uri.withAppendedPath(Contacts.CONTENT_MULTI_VCARD_URI,
                 Uri.encode(uriListBuilder.toString()));
     } finally {
         cursor.close();
     }
 }
 

CONTENT_STREQUENT_FILTER_URI

public static final Uri CONTENT_STREQUENT_FILTER_URI

The content:// style URI used for "type-to-filter" functionality on the CONTENT_STREQUENT_URI URI. The filter string will be used to match various parts of the contact name. The filter argument should be passed as an additional path segment after this URI.

Caution: If you publish your app to the Google Play Store, this field doesn't sort results based on contacts frequency. For more information, see the Contacts Provider page.

CONTENT_STREQUENT_URI

public static final Uri CONTENT_STREQUENT_URI

The content:// style URI for this table joined with useful data from ContactsContract.Data, filtered to include only starred contacts. Frequent contacts are no longer included in the result as of Android version Build.VERSION_CODES.Q.

Caution: If you publish your app to the Google Play Store, this field doesn't sort results based on contacts frequency. For more information, see the Contacts Provider page.

CONTENT_URI

public static final Uri CONTENT_URI

The content:// style URI for this table

CONTENT_VCARD_URI

public static final Uri CONTENT_VCARD_URI

Base Uri for referencing a single Contacts entry, created by appending ContactsContract.ContactsColumns.LOOKUP_KEY using Uri#withAppendedPath(Uri, String). Provides OpenableColumns columns when queried, or returns the referenced contact formatted as a vCard when opened through ContentResolver#openAssetFileDescriptor(Uri, String).

ENTERPRISE_CONTENT_FILTER_URI

public static final Uri ENTERPRISE_CONTENT_FILTER_URI

It supports the similar semantics as CONTENT_FILTER_URI and returns the same columns. This URI requires ContactsContract#DIRECTORY_PARAM_KEY in parameters, otherwise it will throw IllegalArgumentException. The passed directory can belong either to the calling user or to a managed profile that is linked to it.

ENTERPRISE_CONTENT_URI

public static final Uri ENTERPRISE_CONTENT_URI

URI used for getting all contacts from both the calling user and the managed profile that is linked to it.

It supports the same semantics as CONTENT_URI and returns the same columns.
If the calling user has no managed profile, it behaves in the exact same way as CONTENT_URI.
If there is a managed profile linked to the calling user, it will return merged results from both.

Note: this query returns the calling user results before the managed profile results, and this order is not affected by the sorting parameter.

If a result is from the managed profile, the following changes are made to the data:

• ContactsContract.ContactsColumns.PHOTO_THUMBNAIL_URI and ContactsContract.ContactsColumns.PHOTO_URI will be rewritten to special URIs. Use ContentResolver#openAssetFileDescriptor or its siblings to load pictures from them.
• ContactsContract.ContactsColumns.PHOTO_ID and ContactsContract.ContactsColumns.PHOTO_FILE_ID will be set to null. Don't use them.
• BaseColumns._ID and ContactsContract.ContactsColumns.LOOKUP_KEY will be replaced with artificial values. These values will be consistent across multiple queries, but do not use them in places that do not explicitly say they accept them. If they are used in the selection param in ContentProvider.query(Uri, String, Bundle, CancellationSignal), the result is undefined.
• In order to tell whether a contact is from the managed profile, use ContactsContract.Contacts#isEnterpriseContactId(long).

getLookupUri

public static Uri getLookupUri (ContentResolver resolver, 
                Uri contactUri)

Builds a CONTENT_LOOKUP_URI style Uri describing the requested Contacts entry.

getLookupUri

public static Uri getLookupUri (long contactId, 
                String lookupKey)

Build a CONTENT_LOOKUP_URI lookup Uri using the given ContactsContract.Contacts#_ID and ContactsContract.ContactsColumns.LOOKUP_KEY.

Returns null if unable to construct a valid lookup URI from the provided parameters.

isEnterpriseContactId

public static boolean isEnterpriseContactId (long contactId)

Return true if a contact ID is from the contacts provider on the managed profile. PhoneLookup#ENTERPRISE_CONTENT_FILTER_URI and similar APIs may return such IDs.

lookupContact

public static Uri lookupContact (ContentResolver resolver, 
                Uri lookupUri)

Computes a content URI (see CONTENT_URI) given a lookup URI.

Returns null if the contact cannot be found.

markAsContacted

public static void markAsContacted (ContentResolver resolver, 
                long contactId)

This method was deprecated in API level 16.
Contacts affinity information is no longer supported as of Android version Build.VERSION_CODES.Q. This method is no-op.

Mark a contact as having been contacted. Updates two fields: ContactsContract.ContactOptionsColumns.TIMES_CONTACTED and ContactsContract.ContactOptionsColumns.LAST_TIME_CONTACTED. The TIMES_CONTACTED field is incremented by 1 and the LAST_TIME_CONTACTED field is populated with the current system time.

Caution: If you publish your app to the Google Play Store, this field is obsolete, regardless of Android version. For more information, see the Contacts Provider page.
