- Method Detail
  - onSuccess
```
void onSuccess(HttpResponse response)
```
    Called when the HttpResponse is successfully returned by the HTTP server.
    Receiving a HttpResponse successfully does not necessarily indicate application-layer success; the response statusCode may still indicate an application-layer failure with error-codes such as 404 or 500.
    
    Parameters:
    
    response - The response for the HTTP call.
  - onError
```
void onError(java.lang.Throwable error)
```
    Called when the HttpRequest call could not be executed due an error.
    It is possible that the HTTP server received the request before the failure; examples for such failures are the client-side cancellation of the request written to the wire, the response read timeout, etc.
    
    Parameters:
    
    error - The reason for call failure.
