The only sure way to identify returning users is to maintain your own User database, and ask users to sign-in the first time they use the app. Using OpenID or Facebook Connect can avoid the need for the user to create yet another set of login credentials. Netmobo can provide the User repository - we offer a comprehensive User Management system that is available thru Android SDK or REST API.
