ContactsContract.Data

public static final class ContactsContract.Data
extends Object implements ContactsContract.DataColumnsWithJoins

Constants for the data table, which contains data points tied to a raw contact. Each row of the data table is typically used to store a single piece of contact information (such as a phone number) and its associated metadata (such as whether it is a work or home number).

Data kinds

Data is a generic table that can hold any kind of contact data. The kind of data stored in a given row is specified by the row's MIMETYPE value, which determines the meaning of the generic columns DATA1 through DATA15. For example, if the data kind is Phone.CONTENT_ITEM_TYPE, then the column DATA1 stores the phone number, but if the data kind is Email.CONTENT_ITEM_TYPE, then DATA1 stores the email address. Sync adapters and applications can introduce their own data kinds.

ContactsContract defines a small number of pre-defined data kinds, e.g. ContactsContract.CommonDataKinds.Phone, ContactsContract.CommonDataKinds.Email etc. As a convenience, these classes define data kind specific aliases for DATA1 etc. For example, Phone.NUMBER is the same as Data.DATA1.

DATA1 is an indexed column and should be used for the data element that is expected to be most frequently used in query selections. For example, in the case of a row representing email addresses DATA1 should probably be used for the email address itself, while DATA2 etc can be used for auxiliary information like type of email address.

By convention, DATA15 is used for storing BLOBs (binary data).

The sync adapter for a given account type must correctly handle every data type used in the corresponding raw contacts. Otherwise it could result in lost or corrupted data.

Similarly, you should refrain from introducing new kinds of data for an other party's account types. For example, if you add a data row for "favorite song" to a raw contact owned by a Google account, it will not get synced to the server, because the Google sync adapter does not know how to handle this data kind. Thus new data kinds are typically introduced along with new account types, i.e. new sync adapters.

Batch operations

Data rows can be inserted/updated/deleted using the traditional insert(Uri, ContentValues), update(Uri, ContentValues, String, String[]) and delete(Uri, String, String[]) methods, however the newer mechanism based on a batch of ContentProviderOperation will prove to be a better choice in almost all cases. All operations in a batch are executed in a single transaction, which ensures that the phone-side and server-side state of a raw contact are always consistent. Also, the batch-based approach is far more efficient: not only are the database operations faster when executed in a single transaction, but also sending a batch of commands to the content provider saves a lot of time on context switching between your process and the process in which the content provider runs.

The flip side of using batched operations is that a large batch may lock up the database for a long time preventing other applications from accessing data and potentially causing ANRs ("Application Not Responding" dialogs.)

To avoid such lockups of the database, make sure to insert "yield points" in the batch. A yield point indicates to the content provider that before executing the next operation it can commit the changes that have already been made, yield to other requests, open another transaction and continue processing operations. A yield point will not automatically commit the transaction, but only if there is another request waiting on the database. Normally a sync adapter should insert a yield point at the beginning of each raw contact operation sequence in the batch. See withYieldAllowed(boolean).

Operations

Insert

An individual data row can be inserted using the traditional insert(Uri, ContentValues) method. Multiple rows should always be inserted as a batch.

An example of a traditional insert:

 ContentValues values = new ContentValues();
 values.put(Data.RAW_CONTACT_ID, rawContactId);
 values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
 values.put(Phone.NUMBER, "1-800-GOOG-411");
 values.put(Phone.TYPE, Phone.TYPE_CUSTOM);
 values.put(Phone.LABEL, "free directory assistance");
 Uri dataUri = getContentResolver().insert(Data.CONTENT_URI, values);
 

The same done using ContentProviderOperations:

 ArrayList<ContentProviderOperation> ops =
          new ArrayList<ContentProviderOperation>();

 ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
          .withValue(Data.RAW_CONTACT_ID, rawContactId)
          .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
          .withValue(Phone.NUMBER, "1-800-GOOG-411")
          .withValue(Phone.TYPE, Phone.TYPE_CUSTOM)
          .withValue(Phone.LABEL, "free directory assistance")
          .build());
 getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
 

Update

Just as with insert, update can be done incrementally or as a batch, the batch mode being the preferred method:

 ArrayList<ContentProviderOperation> ops =
          new ArrayList<ContentProviderOperation>();

 ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
          .withSelection(Data._ID + "=?", new String[]{String.valueOf(dataId)})
          .withValue(Email.DATA, "somebody@android.com")
          .build());
 getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
 

Delete

Just as with insert and update, deletion can be done either using the delete(Uri, String, String[]) method or using a ContentProviderOperation:

 ArrayList<ContentProviderOperation> ops =
          new ArrayList<ContentProviderOperation>();

 ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
          .withSelection(Data._ID + "=?", new String[]{String.valueOf(dataId)})
          .build());
 getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
 

Query

Finding all Data of a given type for a given contact

 Cursor c = getContentResolver().query(Data.CONTENT_URI,
          new String[] {Data._ID, Phone.NUMBER, Phone.TYPE, Phone.LABEL},
          Data.CONTACT_ID + "=?" + " AND "
                  + Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
          new String[] {String.valueOf(contactId)}, null);
 

Finding all Data of a given type for a given raw contact

 Cursor c = getContentResolver().query(Data.CONTENT_URI,
          new String[] {Data._ID, Phone.NUMBER, Phone.TYPE, Phone.LABEL},
          Data.RAW_CONTACT_ID + "=?" + " AND "
                  + Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
          new String[] {String.valueOf(rawContactId)}, null);
 

Finding all Data for a given raw contact

Most sync adapters will want to read all data rows for a raw contact along with the raw contact itself. For that you should use the ContactsContract.RawContactsEntity. See also ContactsContract.RawContacts.

Columns

Many columns are available via a CONTENT_URI query. For best performance you should explicitly specify a projection to only those columns that you need.

Some columns from the most recent associated status update are also available through an implicit join.

Some columns from the associated raw contact are also available through an implicit join. The other columns are excluded as uninteresting in this context.

The ID column for the associated aggregated contact table ContactsContract.Contacts is available via the implicit join to the ContactsContract.RawContacts table, see above. The remaining columns from this table are also available, through an implicit join. This facilitates lookup by the value of a single data element, such as the email address.
