[英]Google Drive Android API - Invalid DriveId and Null ResourceId
[英]Cannot find DriveId. Are you authorized to view this file? Android google drive integration
我使用github下面的代码,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。
我已经阅读了关于Google驱动器集成的分配,我想将STRING保存到Google驱动器中并且还要检索,我已经使用了这个演示,但它给了我错误。 请有人为我提供我的要求的演示

如消息所述,您的应用需要获得授权才能查看特定文件以进行编辑,因为您的应用具有Drive.File范围访问权限。
您可以通过让用户在打开的文件对话框中选择,或者通过创建文件来获得访问特定文件的权限。
可能是你把ResourceId与DriveId混淆了。 尝试将ResourceId用于EXISTING_FOLDER_ID或EXISTING_FILE_ID。
你可以使用它
driveId.getResourceId().toString()
问题是您正在使用driveId访问文件或文件夹。 这是错的。 您应该使用该driveid的resourceid,如下所示:
BaseDemoActivity.EXISTING_FOLDER_ID = driveId.getResourceId().toString();
将EXISTING_FOLDER_ID
从静态更改为非静态。 并使用该ID进一步使用。
