public static void createNewGroup(String name)
    {
        try
    {
        ContentValues groupValues = new ContentValues();
        groupValues.put(Groups.TITLE, name);
        groupValues.put(Groups.SHOULD_SYNC, true);
        groupValues.put(Groups.GROUP_VISIBLE, 1);
        groupValues.putNull(Groups.ACCOUNT_TYPE);
        groupValues.putNull(Groups.ACCOUNT_NAME);
        getContentResolver().insert(Groups.CONTENT_URI, groupValues);
        return true;
    }
    catch (Exception e){}
    }

public static Uri addContactToGroup(String rawContactId,String groupId)
    {

            ContentValues values = new ContentValues();
            values.put(Data.RAW_CONTACT_ID, rawContactId);
            values.put(GroupMembership.GROUP_ROW_ID, groupId);
            values.put(Data.MIMETYPE, GroupMembership.CONTENT_ITEM_TYPE);

            return getContentResolver().insert(Data.CONTENT_URI, values);
        }

        Uri uri = ContactsContract.Data.CONTENT_URI;
        String[] columns = new String[] { GroupMembership.GROUP_ROW_ID };
        String where = Data.CONTACT_ID + " = ? AND " + Data.MIMETYPE + " = ?";
        String[] args = new String[] {contactId, GroupMembership.CONTENT_ITEM_TYPE };
