dialogutil class code:-

   public class dialogutils {      public static progressdialog showprogressdialog(context context, string message) {         progressdialog m_dialog = new progressdialog(context);         m_dialog.setmessage(message);         m_dialog.setprogressstyle(progressdialog.style_spinner);         m_dialog.setcancelable(false);         m_dialog.show();         return m_dialog;     } }

progress dialog implementation in fragment "a"

m_dialog = dialogutils.showprogressdialog(getcontext(), "loading...");          final string m_deallistingurl = "http://202.131.1.132:8080/ireward/rest/json/metallica/getdeallistinjson";         jsonobjectrequest jsonobjectrequest = new jsonobjectrequest(request.method.post, m_deallistingurl, jsonobject, new response.listener<jsonobject>() {             @override             public void onresponse(jsonobject response) {                 log.i(tag, "server response:-" + response);                 if (m_dialog != null && m_dialog.isshowing()) {                     m_dialog.dismiss();                 }

try this:

dialogutils.showprogressdialog(getactivity(), "loading...");

use getactivity() instead of getcontext()
