Question

I was wondering if there’s a remote file availability check using Flex-AIR. Not a local file.

Example: For displaying a image place holder instead of a broken image icon.

image.source = imageUrl + "/__default.gif";

Thanks.

Answer 1

Listen for the ioError and httpStatus events.

1. ioError – “Dispatched when an input/output error occurs.”

2. httpStatus – “Dispatched when a network request is made over HTTP and Flash Player or AIR can detect the HTTP status code.”

[Source: Flex AS3 Doc]

Also, the HTTP Status can be:

1xx – Informational;
2xx – Success;
3xx – Redirection;
4xx – Client Error;
5xx – Server Error;

*) xx is a number made out of two digits (e.g. 404 or 200).
