I'm trying to send username and password as basic authorization with JsonObjectRequest. I've tried to Override getHeaders() method but it didn't work. Here is my code:
public class NewPostRequest extends JsonObjectRequest {
    public NewPostRequest(JSONObject requestBody) {
        super(Method.POST, APIConstants.CREATE_POST_URL, requestBody, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                try {
                    long postId = response.getLong("id");
                    NewPostResponse newPostResponse = new NewPostResponse(postId);
                    EventBus.getDefault().post(newPostResponse);
                } catch (JSONException e) {
                    e.printStackTrace();
                    EventBus.getDefault().post(new NewPostResponse(-1));
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                EventBus.getDefault().post(new NewPostResponse(-1));
            }
        });
    }
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        Map<String, String> headers = new HashMap<>();
        String credentials = "****:***********************";
        String auth = "Basic "
                + Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP);
        headers.put("Content-Type", "application/json; charset=utf-8");
        headers.put("Authorization", auth);
        return headers;
    }
    @Override
    protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
        JSONObject jsonObject = null;
        try {
            String data = new String(response.data,
                    HttpHeaderParser.parseCharset(response.headers));
            jsonObject = new JSONObject(data);
        } catch (UnsupportedEncodingException | JSONException e) {
            e.printStackTrace();
        }
        return Response.success(jsonObject, HttpHeaderParser.parseCacheHeaders(response));
    }
}
Error when i used Base64.NO_WRAP:
com.android.volley.AuthFailureError
And when i used Base64.DEFAULT:
java.lang.IllegalArgumentException: Unexpected char 0x0a at 46 in header value: Basic *************************
