FacebookDialog.ShareDialogBu​​ilder在Facebook Android SDK中

Question

我正在使用以下方式通过Android Facebook SDK发布消息

FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(mActivity)
                .setApplicationName("My app")
                .setName("Hi All:")
                .setPicture("https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-prn1/27928_228440670639329_1320586523_n.jpg")
                .setDescription("I've just created a card, Check it out!")
                .setLink(shareLink)
                .build();

要混淆，在Facebook Feed上会插入广告。我的代码出了什么问题？
