Google picker api examples has an file-open example which doesn’t set the app id (setAppId) and an upload example which does it.
I would like to get clarifications:
- when do you need to set the api id?
- Can I have a web application downloading a file from Google drive using the file picker without an app id?
For the Google Drive SDK, always set the App ID.
