I've created a file to Drive root using Google Drive Android API. How can I get this file ID to share it using Google Client Library?

在ResultCallback回调中获取DriveFileResult返回Null:

Getting DriveFileResult in ResultCallback<DriveFileResult> callback returns Null:

String fileId = result.getDriveFile().getDriveId().getResourceId();

推荐答案

回调的是本地正在创建的文件.DriveId 只有在文件同步到服务器时才会有 resourceId.在此之前，getResourceId 将返回 null.

The callback is to the file being created locally. The DriveId will only have a resourceId when the file is synced to the server. Until then getResourceId will return null.

使用 CompletionEvents 在与服务器同步时收到通知.然后调用 getResourceId() 应该会提供您所期望的.

Use CompletionEvents to be notified when syncing with the server has occurred. Then calling getResourceId() should deliver what you are expecting.
