I am developing an Android application for which I would like to add Facebook functionality using Facebook’s Android SDK. I have registered the application and acquired the ID and Secret, but what is the point of the URL? Am I supposed to install something on my website on that specific URL so that I Facebook can do the OAuth key exchange?
If so, then what is it?
Application URL is basically used for callback purposes, so that the
access_tokenmay be returned to the callback and your application handle the returned result.
