我正在使用来自 github 的以下代码,但它显示以下错误:

toast that Cannot find DriveId. Are you authorized to view this file?

我不知道这背后的原因是什么。

我已经阅读了很多关于 Google 驱动器集成的文章,我想将 STRING 保存到 Google 驱动器中并进行检索,我已经使用了这个演示,但它给我错误。请任何人为我的要求提供演示

最佳答案

如消息所述,您的应用需要获得授权才能查看特定文件才能对其进行编辑,因为您的应用拥有 Drive.File scope访问权限。

您可以通过让用户在打开的文件对话框中选择或通过创建文件来获得访问特定文件的授权。
