Send authentication information with volley request

In my android app I have to call a web service which looks like this

I am using the volley to send the request but the result is
VolleyError 401
I have overridden the
method to add the header. but it is not working.
Here is my code.

RequestQueue requestQueue = volleySingleton.getRequestQueue();
requestQueue.add(new JsonObjectRequest(Request.Method.GET, url, new Response.Listener<JSONObject>() {
public void onResponse(JSONObject response) {
Log.e(TAG, "onResponse = \n " + response.toString());
}, new Response.ErrorListener() {
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "response error \n" + error.networkResponse.statusCode);
}) {
protected Map<String, String> getParams() throws AuthFailureError {
try {
Map<String, String> map = new HashMap<String, String>();
String key = "Authorization";
String encodedString = Base64.encodeToString(String.format("%s:%s", "USERNAME", "Password").getBytes(), Base64.NO_WRAP);
String value = String.format("Basic %s", encodedString);
map.put(key, value);
return map;
} catch (Exception e) {
Log.e(TAG, "Authentication Filure" );
return super.getParams();

When i use my browser it shows a dialogue to enter my username and password. How can i send the username and password with the request using volley.
Any help to solve this will be appreciated.

For authentication, IMHO, you should override getHeaders instead of getParams, please try the following:

public Map<String, String> getHeaders() throws AuthFailureError {
       Map<String, String> headers = new HashMap<>();                
       String credentials = "username:password";
       String auth = "Basic "
                        + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
       headers.put("Content-Type", "application/json");
       headers.put("Authorization", auth);
       return headers;

Hope it helps!
