How to get the defined Contact Groups on an Android?

I would like to get a list of Contacts Groups already 开发者_开发技巧defined in the system, how can I do that?

You can query the Contacts.Group table for the available groups.

You can use the Contacts.GroupMembership table to query what group a particular contact is a member of. PERSON_ID is the ID of the contact, GROUP_ID matches the ID of the group.

Note that both these APIs have been deprecated in favour of ContactsContract.Groups and ContactsContract.CommonDataKinds.GroupMembership from 2.0 onwards.
