Using RoboSpice is there a way to get the HTTP Error Code out of an exception?

I looked over Spring-Android closer and it seems getRestTemplate().getForObject(...) throws a HttpClientErrorException when a 401 or any network error occurs.

Looking at the Robo Spice for where they catch that exception I found they catch it in RequestProcessor.java in the processRequest function. They pass the Spring-Android exception in as the throwable inside their SpiceException that inherits from Java exception class.

So you just do the following inside your RoboSpice RequestListener to see if it a 401 UNAUTHORIZED exception.

    private class MyRequestListener implements RequestListener<RESULT> {    public void onRequestFailure( SpiceException arg0 ) {        if(arg0.getCause() instanceof HttpClientErrorException)        {            HttpClientErrorException exception = (HttpClientErrorException)arg0.getCause();            if(exception.getStatusCode().equals(HttpStatus.UNAUTHORIZED))            {                Ln.d("401 ERROR");            }            else            {                Ln.d("Other Network exception");            }        }        else if(arg0 instanceof RequestCancelledException)        {            Ln.d("Cancelled");        }        else        {            Ln.d("Other exception");        }    };    public void onRequestSuccess( RESULT result ) {        Ln.d("Successful request");    }}

I am using the google http client with RoboSpice and has the same issue but was easy to solve with request.setThrowExceptionOnExecuteError(false); and checking the response code on the resulting HttpResponse object

EDIT: the code snippit as requested

HttpRequest request = getHttpRequestFactory().buildPostRequest(new GenericUrl(URL), content);request.setThrowExceptionOnExecuteError(false);HttpResponse response = request.execute();switch(response.getStatusCode())    {        case HttpStatusCodes.STATUS_CODE_UNAUTHORIZED:            return new MyBaseResponse(responseBody);        default:            throw new RuntimeException("not implemented yet");    }

For those who can't resolve HttpClientErrorException into a type, and cannot find any documentations online, (that's me), here is my approach:

In my fragment, here is my listener:

private final class MyRequestListener extends RequestListener<MyResponse> {  @Override  public void onRequestFailure(SpiceException spiceException) {    super.onRequestFailure(spiceException);    if (spiceException instanceof NetworkException) {      NetworkException exception = (NetworkException) spiceException;      if (exception.getCause() instance RetrofitError) {        RetrofitError error = (RetrofitError) exception.getCause();        int httpErrorCode = error.getResponse().getStatus();        // handle the error properly...        return;      }    }    // show generic error message  }}

Hope this maybe helpful to someone.

I would move the whole if clause into a static function so it can be reused. Just return 0 if exception doesn't match. And I haven't verify if any of the casting can be removed...
