Android Facebook SDK 3.0 Login Failed - An error has occurred. Please try again later

I am following this tutorial https://developers.facebook.com/docs/howtos/androidsdk/3.0/native-login/ to login. It works with facebook native app, but without native app, first it shows error, then I click OK, then click Login button again, it works. I don't understand why it doesn't work the first time?

I do not understand what the problem is? This is mistake?

Updated: Here is the code.

    btnFacebook.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            Session session = Session.getActiveSession();

            if (!session.isOpened() && !session.isClosed()) {
                session.openForRead(new Session.OpenRequest(
                        UserLoginActivity.this).setPermissions(
                        Arrays.asList("basic_info", "email")).setCallback(
                        statusCallback));
            } 
            else {
                Session.openActiveSession(UserLoginActivity.this, true,
                        statusCallback);
            }
        }
    });


        private class SessionStatusCallback implements Session.StatusCallback {
    @Override
    public void call(Session session, SessionState state,
            Exception exception) {
        if (session.isOpened()) {
            final String token = session.getAccessToken();
            Request.executeMeRequestAsync(session,
                    new Request.GraphUserCallback() {
                        @Override
                        public void onCompleted(GraphUser user,
                                Response response) {
                            if (user != null) { 
                                new AsyncFaceLogin(UserLoginActivity.this)
                                .execute(user.getId(),user.getFirstName(),user.getLastName(),(String)user.getProperty("email"),token);
                            }
                        }
                    });
        }
    }
}
