问题是来自' DriveId.getResourceId() ' 的'resourceID' 在新创建的文件(' DriveFolder.createFile(GAC,meta,cont) '的产品)上不可用(返回NULL ).如果通过常规列表或查询过程检索文件,则'resourceID'是正确的.

我怀疑这是一个时间/延迟问题,但目前尚不清楚是否存在强制刷新的应用程序操作." Drive.DriveApi.requestSync(GAC) "似乎没有任何效果.

我想将Google云端硬盘与我在Google Developers Console中注册我的应用的应用集成.我从https://github.com/googledrive/android-demos获得了一个示例.通过这个我可以在Google驱动器的根文件夹中创建一个文件,文件夹,但问题是我无法在其中创建文件或文件夹现有文件夹.在这种情况下,我得到一个祝酒词"找不到DriveId.您是否有权查看此文件？" 即我无法获得driveID
