Facebook android sdk 3.0 SSO

android, facebook, facebook-android-sdk, single-sign-on

Solution

I made a helper function that to check if the user is still logged in (or actually has an active session) for me in my app:

public static boolean isActive() {
    Session session = Session.getActiveSession();
    if (session == null) {
        return false;
    }
    return session.isOpened();
}

Problem

In previous versions of the Facebook SDK we could check if a user is still signed in by using tokens. In the new 3.0 version I can't find another way other than invoking `openSession()` to check if the user is still logged in with `SSO`. But `openSession()` automatically invokes the login if the user is not saved and I don't want that. I only want to check SSO. How do I do this?
