已成功从Android应用程序发送，但邮件未在Facebook时间轴上显示

Question

我正在尝试通过使用以下方法发布到朋友时间轴形成一个Android应用程序，虽然，我得到一个帖子ID，并且没有显示错误或异常，帖子不在用户那里时间轴，除非用户是我自己的时间表。 只有当我发布到自己的时间轴时，帖子才会显示正常。 欣赏任何想法和帮助。 感谢..

private void publishFeedDialog(GraphUser user) {
    Bundle params = new Bundle();
    params.putString("name", "Facebook SDK for Android");
    params.putString("to",user.getId() );//user.getId());
    params.putString("caption", "Build great social apps and get more installs.");
    params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    params.putString("link", "https://developers.facebook.com/android");
    params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
