Add custom headers in volley request

Question

I have a Volley Request code

RequestQueue queue = Volley.newRequestQueue(this);
String url =;

// Request a string response from the provided U         


        

Answer 1

Override getHeaders in request like:

 StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
            new Response.Listener() {
                @Override
                public void onResponse(String response) {
                    // Display the first 500 characters of the response string.
                    mTextView.setText("Response is: "+ response.substring(0,500));
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            mTextView.setText("That didn't work!");
        }
    }){
        @Override
        public Map getHeaders() throws AuthFailureError {
            Map params =  super.getHeaders();
            if(params==null)params = new HashMap<>();
            params.put("Authorization","Your authorization");
            //..add other headers
            return params;
        }
    };
