title: Is there a way to generate a user id for android?
body: <p>Is there a way to generate a user id for new users like 'yik yak' does, removing the need of a login id and password? i really want to implement this as the app i am creating is not e-commerce so there is no need for such tight security. 
  Also would there be a way to display the generated user so users could add each other as friends?</p>
