Facebook is about to sunset (abandon) Facebook Connect, forcing developers with working apps and sites to do everything all over again.
It would really be nice if they bought us dinner first. But I digress.
One casualty of this change early on is making Facebook OAuth 2.0 authentication scheme work on Android.
Or not, as the case is proving to be.
If you’ve written an OAuth implementation on Android, more likely than not you’ve used a library like signpost and implemented a custom protocol to direct your callback to an appropriate intent in your application to handle the callback package.
Except that apparently Facebook only recognizes http and https as “legit” callback protocols.
In short, for the time being, those of you looking to do an Android version of the new Graph API and FB OAuth 2.0 scheme are hosed.
