java - Unable to signUp a new user in quickblox -

i have been trying add new user quickblox referring code provided in sample-chat provided android.

i using following code.

authenticate using app_id,auth_id , secret_id.

qbsettings.getinstance().fastconfiginit(app_id, auth_key, auth_secret); 

create application session

qbauth.createsession(new qbentitycallbackimpl<qbsession>() { @override             public void onsuccess(qbsession qbsession, bundle bundle) {                 getalluser();             }              @override             public void onerror(list<string> errors) {                 // print errors came server                 dialogutils.showlong(context, errors.get(0));                 progressbar.setvisibility(view.invisible);             }         });     }  //sign new user  // register new user  final qbuser user = new qbuser("userlogin", "userpassword");  qbusers.signup(user, new qbentitycallbackimpl<qbuser>() {     @override     public void onsuccess(qbuser user, bundle args) {         // success     }      @override     public void onerror(list<string> errors) {        // error     } }); 

user signup not working.i able login using registered user via quickblox administration panel.

i want create new user login , create chat service same login.i new quickblox , java appreciated.

the right way call qbusers.signup inside createsession onsuccess block

because these quickblox queries asynchronous
