Friends email issue while getting from facebook api

I'm trying to get friends email addresses using facebook api like that
private static final List<String> PERMISSIONS =
Arrays.asList("publish_actions","read_stream", "email",
"user_about_me", "friends_about_me", "friends_notes");
String fqlQuery = "SELECT uid, name, pic_square, contact_email FROM
user WHERE uid IN " + "(SELECT uid2 FROM friend WHERE uid1 = me())";
Bundle params = new Bundle();
params.putString("q", fqlQuery);
Session session = Session.getActiveSession();
Request request = new Request(session, "/fql", params, HttpMethod.GET,
new Request.Callback()
{
public void onCompleted(Response response)
{
Log.e("log_tag", "response: "+response);
}
});
Request.executeBatchAsync(request);
But I cant get success for email but ya i am getting other values. Any one
have idea about that?
I also need to get contact numbers of friends. Is it possible? Also guide
me for that.
Thanks
