Ошибка в OTP проверочный код андроида

Question

Я Создание приложения, которые выполняют способ проверки OTP .. я реализовал код, как описано в этой ссылке http://www.androidhive.info/2015/08/android-adding-sms-verification-like-whatsapp-part-2/

Но когда я нажмите кнопку NEXT, в приложении приложение является сила закрывания

функция я получаю ошибку является:

private void requestForSMS(final String name, final String email, final String mobile) { 
     StringRequest strReq = new StringRequest(Request.Method.POST, 
       Config.URL_REQUEST_SMS, new Response.Listener<String>() { 

      @Override 
      public void onResponse(String response) { 
       Log.d(TAG, response.toString()); 

       try { 
        JSONObject responseObj = new JSONObject(response); 

        // Parsing json object response 
        // response will be a json object 
        boolean error = responseObj.getBoolean("error"); 
        String message = responseObj.getString("message"); 

        // checking for error, if not error SMS is initiated 
        // device should receive it shortly 
        if (!error) { 
         // boolean flag saying device is waiting for sms 
         pref.setIsWaitingForSms(true); 

         // moving the screen to next pager item i.e otp screen 
         viewPager.setCurrentItem(1); 
         txtEditMobile.setText(pref.getMobileNumber()); 
         layoutEditMobile.setVisibility(View.VISIBLE); 

         Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show(); 

        } else { 
         Toast.makeText(getApplicationContext(), 
           "Error: " + message, 
           Toast.LENGTH_LONG).show(); 
        } 

        // hiding the progress bar 
        progressBar.setVisibility(View.GONE); 

       } catch (JSONException e) { 
        //Toast.makeText(getApplicationContext(),"Error: " + e.getMessage(),Toast.LENGTH_LONG).show(); 

        progressBar.setVisibility(View.GONE); 
       } 

      } 
     }, new Response.ErrorListener() { 

      @Override 
      public void onErrorResponse(VolleyError error) { 
       //Log.e(TAG, "Error: " + error.getMessage()); 
       //Toast.makeText(getApplicationContext(),error.getMessage(), Toast.LENGTH_SHORT).show(); 
       progressBar.setVisibility(View.GONE); 
      } 
     }) { 

      /** 
      * Passing user parameters to our server 
      * @return 
      */ 
      @Override 
      protected Map<String, String> getParams() { 
       Map<String, String> params = new HashMap<String, String>(); 
       params.put("name", name); 
       params.put("email", email); 
       params.put("mobile", mobile); 

       //Log.e(TAG, "Posting params: " + params.toString()); 

       return params; 
      } 

     }; 

     // Adding request to request queue 
     MyApplication.getInstance().addToRequestQueue(strReq); 
    } 

Log является:
