Android FBConnect: unable to get extended premissions

when I login in and try get extended premissins dis开发者_运维问答plays "You must be logged in to Facebook to use this feature". How can I get extended premissions for posting messages in facebook?

Haven't used Facebook Connect on the Android yet, but I have used it on a website. I'm thinking they are similar. I have two suggestions:

• Use streamPublish() instead of extended permissions -- although this will pop up a dialog every time you call it, or
• If you really have to use extended permissions, you have to call requireSession() before asking for permissions, to log the user in.

As I said, this is the way this should be done using Facebook Connect on a website. I'm not sure it's the same on Android, but I'm guessing it is.
