行中引发异常

 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;
            }

这个例外是什么意思以及如何解决它？

Answer 1

Dmytro，根据我的评论，我已经汇总了几篇文章，完全解释了开设Facebook会话并请求其他权限：here和here。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：您获得此异常的原因是您不能请求非开放会话的新权限。你需要打开你的请求新权限或制作其他Facebook API之前的会话要求。我在上面链接的文章中整理了一个指南确保Facebook API请求（例如发布到用户的Feed）等等，直到用户的会话打开并且没有用户具有所需的权限。

Answer 2

这意味着您请求权限的会话处于非活动/已过期状态。您需要在请求权限之前重新建立会话。

Answer 3

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