Read more about Volley Error handling at Android Volley example with Error Handling

Every Volley requests has two callbacks -one for success and one for failure.Based on the type of VolleyError parameter in the onErrorResponse callback developers can show a sensible message to the users as shown below

@Override
public void onErrorResponse (VolleyError error){

   if (error instanceof TimeoutError || error instanceof NoConnectionError) {
     //This indicates that the reuest has either time out or there is no connection

   } else if (error instanceof AuthFailureError) {
     // Error indicating that there was an Authentication Failure while performing the request

   } else if (error instanceof ServerError) {
     //Indicates that the server responded with a error response

   } else if (error instanceof NetworkError) {
     //Indicates that there was network error while performing the request

   } else if (error instanceof ParseError) {
      // Indicates that the server response could not be parsed

   }
}
