Facebook getName（）

Question

我做了以下操作，尝试使用Facebook的Graph API获取用户名。我有登录按钮，但用户总是在onCompleted（..）

上显示为null

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    if (state.isOpened()) {
        Log.i(TAG, "Logged in..." + session.toString());

        // Request user data and show the results
        Request.newMeRequest(session, new Request.GraphUserCallback() {
                    public void onCompleted(GraphUser user, Response response) {
                        if (user == null)
                        {
                            Log.i("", "no!");
                        }
                        else {
                            Log.i("", "YES " + user.getName());
                        }
                    }
                }
        ).executeAsync();

    } else if (state.isClosed()) {
        Log.i(TAG, "Logged out...");
    }
}
