From a usability perspective it is kind of a pain to be required to login with two separate accounts to use a service.
I recommend that instead of using google accounts at all, you just use the oauth authentication api from DropBox: https://www.dropbox.com/developers/start/authentication#pyth...
You should be able to achieve the same thing you're doing now with google+dropbox with just dropbox.
