Difference session.isOpened() and session.getState().isOpened()

Question

Can someone tell the difference between those states? And when to use which one?

Answer 1

According to the facebook sdk reference page:

SessionState.isOpened()

Returns a boolean indicating whether the state represents a successfully opened state in which the Session can be used with a Request.

and

Session.isOpened()

Returns a boolean indicating whether the session is opened.

Maybe there's no real difference between them, but I recommend to use Session.isOpened() whenever you just want to know if the session is opened and the Session.getState().isOpened() if you need to know if it can be used with a Request.
