FB.Mobile.RefreshCurrentAccessToken

The Facebook SDK will manage the lifetime of access tokens for you and will handle making sure that tokens are refreshed before they expire.

You can use this method to manually refresh the current access token granted to the application by the user in order to retrieve up-to-date permissions, and extend the expiration date, if extension is possible.
