Facebook App Invite不显示朋友对话框:无法打开VMSTAT文件Java.io.filenotfound

我正在尝试在Android平台上以Unity进行Facebook应用程序邀请。我目前正在使用Facebook SDK 4.11.0和Unity 2017.2.0。

这里的流量是：

Facebook Init在应用启动
用户按下应用程序邀请按钮
检查用户是否具有 Publish_actions 和 user_friends read/witer permissions。
如果未授予权限，请要求登录。
如果成功，请通过API邀请Facebook应用程序。

应用程序邀请的代码如下：

public void FbAppInvite(string message)
{
    FacebookHelper.AuthenticateWithPublishPermissions(new List<string>() { "publish_actions" },
        (bool publishSuccess) =>
        {
            if (publishSuccess)
            {
                FacebookHelper.AuthenticateWithReadPermissions(new List<string>() { "user_friends" }, (bool success) =>
                {
                    if (success)
                    {
                        FB.Mobile.AppInvite(
                            new System.Uri("https://mycustomurl"),
                            new System.Uri("https://mycustomimage.png"),
                            (IAppInviteResult result) =>
                            {
                                if (string.IsNullOrEmpty(result.Error)
                                    && !result.Cancelled)
                                {
                                    object o;
                                    if (result.ResultDictionary != null
                                        && result.ResultDictionary.TryGetValue("did_complete", out o))
                                    {
                                        if (o.Equals(true))
                                        {
                                            // Success
                                        }
                                    }
                                }
                            }
                        );
                    }
                });
            }
        }
    );
}

在这一点上，该应用程序试图进行身份验证(返回成功(，并最终使应用程序邀请调用。然后，该应用在白色屏幕上冻结了几秒钟，然后什么也没有发生。.朋友对话框从未显示。这是恢复的日志：

我使用的是Facebook应用中LO LO的测试用户(在应用程序控制台中配置(，而我的真实用户则配置为管理员。

看起来设备中有一个文件 vmstat 试图打开它没有许可的情况，不太知道为什么。

我已经尝试授予Facebook应用程序在设备中要求的所有权限，但仍然没有运气。

我正在为此请求使用正确的权限吗？想法是用户向他们的朋友共享应用程序(安装(。

我的设备目前处于Android 8.1.0。这可能是一个问题吗？

有什么想法？

很可能是因为Facebook应用程序邀请已于2018年2月5日起已弃用。
