How do I get a user's email from the Dropbox sign-in process?

I am new to Dropbox 1.2, in my application I need to get the user's email after the user logs into Dropbox, in Dropbox 1.0 I got this value from the " email

" property DBAccountInfo.h

, but after I've update in the Dropbox 1.2 API, I didn't find this property , can anyone help me how to get this information by email to user? thank

UPDATE

I have read the Dropbox 1.0 to 1.1 changelog "Removed email from DBAccountInfo. This field has been deprecated from the API. UserId is the recommended way to link to an account.

therefore, we can no longer receive this information by email.
