Android上的Facebook图形请求错误

我正在尝试制作一个虚拟应用程序,以便与Facebook的Android SDK一起玩。我目前拥有SSO,可以使用以下代码存储身份验证令牌。从本质上讲,它只是登录,然后应该打一个电话来获取userId,然后当点击测试按钮将其打印在屏幕上时再打另一个电话。

身份验证令牌打印得很好,但当我试图调用该图时,我不断收到Facebook错误。奇怪的是,当我从日志中复制请求并将其发布到浏览器中时,我会得到一个有效的json响应。

我知道直接从Facebook调用并不理想(异步请求可能对一个经过优化的应用程序更好),但目前,我只是想让基本的api发挥作用。

有什么建议吗?
