无法成功托管云锚并无法从Google Cloud Anchor API检索云锚ID

Question

我正在尝试在Google Arcore Cloud API上托管云锚。我已在清单中包含api密钥。我还可以看到当我要托管锚点时android设备发出的请求，并且从api发送回了响应，如下图所示。

但是，即使我已经设置了更新侦听器，云锚状态也永远不会更改为SUCCESS，并且我也从未收到过来自Google的云锚ID，如下所示。通过调试程序，我可以看到AppAnchorState从未从NONE更改过，但是我没有设法收集任何其他信息。

我同时使用Sceneform和Arcore 1.7.0。下面是我用来尝试托管锚点并从api返回云锚点ID的代码。

在此阶段我一直在努力解决这个问题，因此能提供任何帮助将不胜感激。
