Answer 1

Sharing is not currently supported in the Android-specific API (sorry for the confusing wording in the blog post.)

You can fallback to the web API to do sharing (e.g, modifying permissions). To use the web API, use DriveId.getResourceId().

However, files that are in the AppFolder are special. Items in that folder cannot currently be shared. They are only visible to your app and the specific user.
