Code : for getting time from the json url

            JSONObject obj = new JSONObject(result);
            if (obj.getString("status").equals("success")) {
                 JSONArray arr = obj.getJSONArray("response");
                 UserNotificationTime jour;
                 for (int i = 0; i < arr.length(); i++) {
                    obj = arr.getJSONObject(i);
                    jour = new UserNotificationTime();
                    jour.set_breakfast_time(obj.getString("breakfast_time"));
                    j_pref_bkTime = jour.get_breakfast_time();
                    j_editor.putString("j_bktime", j_pref_bkTime);
                    j_editor.commit();
               }
            } else {
                Toast.makeText(getApplicationContext(),
                        obj.getString("response"), Toast.LENGTH_SHORT)
                        .show();
            }

i got time in j_pref_bkTime with current time i got current time from the

           j_pref_bkTime = prefs.getString("j_bktime", "OFF"); // get json time from the shared preference


           int hours = new Time(System.currentTimeMillis()).getHours();
           int minute = new Time(System.currentTimeMillis()).getMinutes();

           String time = hours + ":" + minute;

           //  splits json time (hour and minute to comapare with current time)
            StringTokenizer tokens_bk = new StringTokenizer(j_pref_bkTime,
                    ":");
            String first_bk = tokens_bk.nextToken();
            String second_bk = tokens_bk.nextToken();
            String final_bktime = first_bk.trim() + ":" + second_bk.trim();

           if (time.trim().equals(final_bktime.trim())) {

             // perform some action here but it call when our app open and do some 
                into this but i want to call this code also when application is 
                close  or open means how to compare this code-condition to call 
                any time this body when current time match to json time.

          }

I don't think it is necessary to check if the given time is equal to the current time. Instead when you get your JSON, make an alarm on the time of the JSON. Then show a notification when the alarm goes off. Android will automatically check if the alarm time (so the JSON time) is equal to the current time. If you make an alarm and notification it will work even if your application is not running.
