您好，我必须从一个托管 fragment 的 Activity 中发布我的状态，并且在第一次使用应用程序时登录到应用程序后，当我尝试更新状态时出现异常。我得到这个异常(exception)。
“ session :尝试为具有待处理请求的 session 请求新权限。”
这是我的 fragment 代码

publishStory() 方法是在我的墙上张贴的实际方法。正在从主机 Activity 调用此方法。并且 UILifeCycleHelper 处理是在 fragment 的 onActivityResult 中完成的，但是 fragment 的 onActivityResult 在发布故事后没有被调用。只有当用户第一次使用该应用程序并尝试发布到 facebook 时才会发生这种情况。 如果他注销并再次登录，那么他可以成功发布并且不会引发异常。 任何形式的帮助将不胜感激，
感谢和问候， 穆纳扎

嘿，改用这个库来进行 facebook 授权。
关于android - 从android更新状态时Facebook挂起授权异常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19005186/
