Google Drive API - the name must not be empty: null (But I had passed valid account name to GoogleAccountCredential)

Question

Recently, I have Android code which accesses to Google Drive. I\'m using Google APIs Client Library for Java instead of Google Play services client

Answer 1

It looks like the Drive API Client Library for Java calls into GoogleAuthUtil.getToken(), which requires the GET_ACCOUNTS permission. You need to have that permission in your manifest and request it at runtime, as appropriate.

UPDATE: With Google Drive REST v3 API, GET_ACCOUNTS permission is not required. Instead, Email permission is required. You can ask for it by calling GoogleSignInOptions.Builder.requestEmail.
