Is it possible to present the Google Picker to a user who isn't logged in with her Google account? I would like to let the user select files from a shared Google Drive of the Google account of my website. I can access these files with OAuth on the server. But is it also possible to present the files with Google Picker? Maybe with this method:
PickerBuilder.setOAuthToken(string)
Sets an OAuth token to use for authenticating the current user. Depending on the scope of the token, only certain views will display data. Valid scopes are Google Docs, Drive, and Photos. This method should be used instead of .setAuthUser when a user is authenticated with OAuth.
I have tried this and I think it is not possible. Or is it?
