error Invalid Call Back URL Failed in Flickr API

I need to implement flickr in my app.i just downloaded the api.In that开发者_JAVA百科 i founded the sample(SnapAndRun).That sample is working,but i am getting issues saying that call back URL failed .please let where i have to modify it...

You will have to set up this URL on the Flickr website against your app. It is the url that Flickr will call after user authentication. This will be your application's custom url scheme. But for the example application, you will need to set it up as snapnrun://auth?.
