This is what I am using in my projects.

        @Override
        public void onErrorResponse(VolleyError error) {
            if(error instanceof NoConnectionError){
                ConnectivityManager cm = (ConnectivityManager)mContext
                        .getSystemService(Context.CONNECTIVITY_SERVICE);
                NetworkInfo activeNetwork = null;
                if (cm != null) {
                    activeNetwork = cm.getActiveNetworkInfo();
                }
                if(activeNetwork != null && activeNetwork.isConnectedOrConnecting()){
                    Toast.makeText(getActivity(), "Server is not connected to internet.",
                            Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getActivity(), "Your device is not connected to internet.",
                            Toast.LENGTH_SHORT).show();
                }
            } else if (error instanceof NetworkError || error.getCause() instanceof ConnectException 
                    || (error.getCause().getMessage() != null 
                    && error.getCause().getMessage().contains("connection"))){
                Toast.makeText(getActivity(), "Your device is not connected to internet.", 
                        Toast.LENGTH_SHORT).show();
            } else if (error.getCause() instanceof MalformedURLException){
                Toast.makeText(getActivity(), "Bad Request.", Toast.LENGTH_SHORT).show();
            } else if (error instanceof ParseError || error.getCause() instanceof IllegalStateException
                    || error.getCause() instanceof JSONException
                    || error.getCause() instanceof XmlPullParserException){
                Toast.makeText(getActivity(), "Parse Error (because of invalid json or xml).", 
                        Toast.LENGTH_SHORT).show();
            } else if (error.getCause() instanceof OutOfMemoryError){
                Toast.makeText(getActivity(), "Out Of Memory Error.", Toast.LENGTH_SHORT).show();
            }else if (error instanceof AuthFailureError){
                Toast.makeText(getActivity(), "server couldn't find the authenticated request.", 
                        Toast.LENGTH_SHORT).show();
            } else if (error instanceof ServerError || error.getCause() instanceof ServerError) {
                Toast.makeText(getActivity(), "Server is not responding.", Toast.LENGTH_SHORT).show();
            }else if (error instanceof TimeoutError || error.getCause() instanceof SocketTimeoutException
                    || error.getCause() instanceof ConnectTimeoutException 
                    || error.getCause() instanceof SocketException
                    || (error.getCause().getMessage() != null 
                    && error.getCause().getMessage().contains("Connection timed out"))) {
                Toast.makeText(getActivity(), "Connection timeout error", 
                        Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getActivity(), "An unknown error occurred.", 
                        Toast.LENGTH_SHORT).show();
            }
        }
