In Android APP of service Account authorization as well as a servlet in Appengine for Google service account for Drive API, Not able to get changes of List for page token it's returning an empty list. But https://developers.google.com/drive/v3/reference/changes/list same pageToken returns list.

   Drive.Changes.List request1 = drive.changes().list("3420");
    ChangeList changes = request1.execute();

Note: same above code returns change list if using GoogleAuthorizationCodeFlow.

I guess it's possible. Based from this thread, maybe you have authenticated with a scope that doesn't give you permission to see those files.

For example, the scope https://www.googleapis.com/auth/drive.file only provides access to files created or opened by the app. You won't be able to access files created in the Google Drive interface or by other apps.

If you want to access all the files, you'll have to use another scope. https://www.googleapis.com/auth/drive, for example, gives you full, permissive scope to access all of a user's files.

You can find information about the available scopes here.

  • While the answer is correct, it would be unusual for a Drive Service Account to contain any files that are not created by the app. By definition, a Service Account is dedicated to a single service/app. – pinoyyid Jun 14 '17 at 21:09
