This is my upload code but every time I am getting this error ------>

11-14 12:20:33.515: INFO/System.out(444):
err code="100" msg="Invalid API Key (Key has invalid format)"

Please help me. Thanks in advance.

Answer 1

If you take a look at the Flickr upload API

100: Invalid API Key: The API key passed was not valid or has expired.

So I guess your API key was incorrect. To use the Flickr API you need to have an application key.

Currently, commercial use of the API is allowed only with prior permission. Requests for API keys intended for commercial use are reviewed by staff.

Here is how to get an API key
