Deep link to a friend's wall in Facebook app (Android)

Starting with Facebook Graph API v2.0 friend-ids are app-scoped.

So how can I launch the Facebook info/wall page of a specific user's friend using the "fb://" scheme (as explained here: http://ift.tt/1G86F0r) with an app-specific friend id?

Looking at Facebook's app manifest it seems they still register to the "facebook://" and "fb://" schemes, so I hope this is still somehow possible.
