well this is my get
    public GraphResponse Get(String query,Bundle parameters)
    {
        final GraphResponse[] respuesta = new GraphResponse[1];
        /* make the API call */
        new GraphRequest(
                AccessToken.getCurrentAccessToken(),
                query,
                parameters,
                HttpMethod.GET,
                new GraphRequest.Callback() {
                    public void onCompleted(GraphResponse response) {
            /* handle the result */
                        respuesta[0] =response;
                    }
                }
        ).executeAndWait();
return  respuesta[0];
    }
and this works fines with me queries now I tried with me/groups query, now if I try get all the group where user is memeber of, I got
{
  "data": [
  ]
}
this happens too on explorer in
https://developers.facebook.com/tools/explorer/
on this last I had choosen all the permission and especial permission and I got the same answer.
then my ask is, If there is not a way for get this list on V2.5 how can I (continue using the version 2.5) "change" for (only) this query the version to 2.3 where it does works?
I tried doing this query   /v2.3/me/groups
but I got blank answer.
My app facebook was created "today"
