                                progressDialog.dismiss();

                                // Showing error message if something goes wrong.
                                Toast.makeText(MainActivity.this, volleyError.toString(), Toast.LENGTH_LONG).show();
                            }

                    @Override
                    protected Map<String, String> getParams() {

                        // Creating Map String Params.
                        Map<String, String> params = new HashMap<String, String>();

                        // Adding All values to Params.
                        params.put("first_name", FirstNameHolder);
                        params.put("last_name", LastNameHolder);
                        params.put("email", EmailHolder);

                        return params;
                    }

                };

                // Creating RequestQueue.
                RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);

                // Adding the StringRequest object into requestQueue.
                requestQueue.add(stringRequest);

            }
        });

    }

    // Creating method to get value from EditText.
    public void GetValueFromEditText(){

        FirstNameHolder = FirstName.getText().toString().trim();
        LastNameHolder = LastName.getText().toString().trim();
        EmailHolder = Email.getText().toString().trim();

    }

}
