jtaylor,
Did you read the example?  It does not do a joint.  Instead it uses a
Uri subpath notation for its child query, within the same table rather
than joining multiple tables.  The references to "group" in the code
are not contact group membership, but rather ExpandableList parent
node/"groups".
