copied!<p>It looks strange because ContactsContract.Contacts does not have ContactsContract.Groups.TITLE column. So I think that you can get group id with the group title you want and then search contacts with the group id. The idea might go like following:</p> <pre><code> public String getGroupIdByTitle(String groupTitle){ try { cursor = mContentResolver.query( ContactsContract.Groups.CONTENT_URI, new String[] {Groups._ID}, Groups.TITLE + "=?", new String[]{groupTitle}, null); while (cursor.moveToNext()){ return cursor.getString(cursor.getColumnIndex(0); } } finally { if (cursor!=null) cursor.close(); } return ""; } public String getGroupIdOfContact(String lookupKey) { String where = String.format("%s=? AND %s=?", Data.LOOKUP_KEY, Data.MIMETYPE); String[] whereArgs = {lookupKey, GroupMembership.CONTENT_ITEM_TYPE}; String groupRowId = ""; Cursor cursor = mContentResolver.query( Data.CONTENT_URI, new String[]{GroupMembership.GROUP_ROW_ID}, where, whereArgs, null); try { if (cursor.moveToNext()) { return cursor.getString(cursor.getColumnIndex(GroupMembership.GROUP_ROW_ID)); } } finally { if (cursor!=null) cursor.close(); } return ""; } public void deleteContactByGroupTitle(String groupTitle) { String targetGroupId = getGroupIdByTitle(groupTitle); Cursor cursor = null; try { cursor = mContentResolver.query(Contacts.CONTENT_URI, null, null, null, null); while (cursor.moveToNext()){ String lookupKey = cursor.getString(cursor.getColumnIndex(Contacts.LOOKUP_KEY)); String groupId = getGroupIdOfContact(lookupKey); if (targetGroupId.equals(groupId)){ //TODO. delete this contact } } } finally { if (cursor!=null) cursor.close(); } } </code></pre> <p>The above code has not tested but I think that basic idea would be same.</p>

Querying!

An individual column

Larger individual text columns get their own page to allow for proper reading.
