android - volley error No authentication challenges found

Question

I am trying to work with some legacy code and have come up against an issue when using volley.

I am trying to get to an api that our main site has and it works fine

Answer 1

I was able to catch this client-side when initializing the volley RequestQueue:

Volley.newRequestQueue(getApplicationContext(), new HurlStack() {
        @Override
        public HttpResponse performRequest(Request request, Map additionalHeaders) {
            try {
                return super.performRequest(request, additionalHeaders);
            } catch (AuthFailureError authFailureError) {
                authFailureError.printStackTrace();
                // Log out / whatever you need to do here
            } catch (IOException e) {
                e.printStackTrace();
                if (e.getMessage().equals("No authentication challenges found")) {
                    // This is the error.  You probably will want to handle any IOException, not just those with the same message.
                }
            }
            return null;
        }
});
