异常在行中抛出

 session.requestNewPublishPermissions(newPermissionsRequest);
 // Check for publish permissions
            List<String> permissions = session.getPermissions();
            if (!isSubsetOf(PERMISSIONS, permissions)) {
                pendingPublishReauthorization = true;
                Session.NewPermissionsRequest newPermissionsRequest = new Session
                        .NewPermissionsRequest(this, PERMISSIONS);


                session.requestNewPublishPermissions(newPermissionsRequest);


                Toast.makeText(getActivity().getApplicationContext(),
                        "Not enough permissions",
                        Toast.LENGTH_SHORT).show();
                return;
            }

这个异常是什么意思以及如何解决它？

Dmytro，根据我的评论，我整理了几篇文章，充分解释了打开 Facebook 会话并请求额外权限：这里和这里。希望您和其他人发现它有益并节省开始使用 SDK 的时间！:)

编辑：您收到此异常的原因是您无法在未打开的会话上请求新权限。您需要在请求新权限或发出其他 Facebook API 请求之前打开会话。我在上面链接的文章中整理了一个指南，确保在用户会话打开并且用户拥有所需权限之前不会发出 Facebook API 请求（例如发布到用户的提要等）。

这意味着您请求权限的会话处于非活动状态/已过期。您需要重新建立会话才能请求权限。

在调用 requestNewPublishPermissions 之前，您是否调用过 session.openForPublish(Session.OpenRequest openRequest)？
