with the 3.1 sdk you can call Session.getActiveSession().closeAndClearTokenInformation()

facebook.logout(mainActivityContex);

or

facebook.logout(this);

in Facebook SDK Facebook.java --`

public String logout(Context context)
        throws MalformedURLException, IOException {
    Util.clearCookies(context);
    Bundle b = new Bundle();
    b.putString("method", "auth.expireSession");
    String response = request(b);
    setAccessToken(null);
    setAccessExpires(0);
    return response;
}`

There's a .logout() method on that Facebook class if I remember correctly. I think you're looking for that.
