Question

我正在使用github中的以下代码，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

Answer 1

正如消息所述，您的应用需要获得授权才能查看特定文件，以便对您的应用进行Drive.File scope访问权限进行编辑。

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。

Answer 2

您可能会将 ResourceId 与 DriveId 混淆。尝试将ResourceId用于EXISTING_FOLDER_ID或EXISTING_FILE_ID。

您可以使用

获取它

driveId.getResourceId().toString()

Answer 3

我相信这可能与我们的discussion here有关。如果是的话，我会建议你关闭它，因为这里的观众更广泛。请参阅此处的github code来处理您的READ / WRITE字符串问题。另一个问题与授权有关。如果您使用的是WIN7 / Eclipse，this may help。相同的信息是here as well。一般来说，不要指望太多的帮助，API是一个非常新的，有点移动的目标。

Answer 4

问题是您正在使用driveId访问文件或文件夹。这是错的。你应该使用那个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。

找不到DriveId。您是否有权查看此文件？ Android谷歌驱动器集成
