java - NoClassDefFoundError when using Android Volley -


i trying make network request using android volley library:

    stringrequest jsobjrequest = new stringrequest(request.method.get,                 network.getfullurl("/account/login"),                 new listener<string>() {                      @override                     public void onresponse(string response) {                         // todo auto-generated method stub                      }                 }, new errorlistener() {                      @override                     public void onerrorresponse(volleyerror error) {                         // todo auto-generated method stub                      }                 });  network.getinstance(this).addtorequestqueue(jsobjrequest);
