I am working on an app that allows user to share their Drive files to friends. But there is a problem of Google App Account, like someone@somadomain.com, of which files cannot be shared with people who are not under that domain. Although the share policy can be changed by admin of somedomain.com, but I prefer not allowing people use my app with Google Apps Account.
I also check this post: How to determine if the account is a Google apps account?. But I don't agree with the idea of checking domain to detect account type. Because people can register Google Account with any email address. I just registered one with my Hotmail, someone@hotmail.com, which has no domain restriction when sharing a file.
Can anyone help with this? Thanks!
