How to send Authorization header in Android using Volley library?

Question

How can I send Authorization header using Volley library in Android for GET method?

This is my request code:

JsonObjectRequest req = new JsonObjectRequest(Request.Method.GET, url,             null, new Response.Listener<JSONObject>() {          @Override         public void onResponse(JSONObject response) {             Log.d("Response", response.toString());             pd.dismiss();                          Toast.makeText(MainActivity.this, "" + response.toString(), Toast.LENGTH_SHORT).show();         }     }, new Response.ErrorListener() {         @Override         public void onErrorResponse(VolleyError error) {             VolleyLog.d("Error", "Error: " + error.getMessage());             Toast.makeText(MainActivity.this, "" + error.getMessage(), Toast.LENGTH_SHORT).show();             pd.dismiss();          }     }) {         @Override         public Map<String, String> getHeaders() throws AuthFailureError {             HashMap<String, String> headers = new HashMap<String, String>();             headers.put("Authorization", "2e96e0a4ff05ba86dc8f778ac49a8dc0");             return headers;         }     };

StringRequest request = new StringRequest(Request.Method.POST, YourUrl, new Response.Listener<String>() {     @Override     public void onResponse(String response) {         if (!response.equals(null)) {             Log.e("Your Array Response", response);                             } else {             Log.e("Your Array Response", "Data Null");         }     }  }, new Response.ErrorListener() {     @Override     public void onErrorResponse(VolleyError error) {         Log.e("error is ", "" + error);     } }) {       //This is for Headers If You Needed     @Override     public Map<String, String> getHeaders() throws AuthFailureError {         Map<String, String> params = new HashMap<String, String>();         params.put("Content-Type", "application/json; charset=UTF-8");         params.put("token", ACCESS_TOKEN);         return params;     }   //Pass Your Parameters here     @Override     protected Map<String, String> getParams() {         Map<String, String> params = new HashMap<String, String>();         params.put("User", UserName);         params.put("Pass", PassWord);         return params;     } }; RequestQueue queue = Volley.newRequestQueue(getApplicationContext()); queue.add(request);

Try following code:

@Override     public Map<String, String> getHeaders() throws AuthFailureError {         String credentials = "username" + ":" + "password";         String base64EncodedCredentials = Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);         HashMap<String, String> headers = new HashMap<>();         headers.put("Authorization", "Basic " + base64EncodedCredentials);         return headers;     }
