Can I perform this Android query with ContentResolver.query()? (LEFT JOIN and CASE)

Question

I am looking to perform the following query (in pseudo-code) on Android:

SELECT C.ID, C.NAME, CASE ISNULL(G.GROUPID,0) = 0 THEN 0 ELSE 1 END INGROUP
FROM CO

You can't do that because ContentResolver has only one query method:

    query(Uri uri, String[] projection, String selection, 
String[] selectionArgs, String sortOrder)

there's no parameter for tables or FROM clauses.
