I know on the Google App engine there is support for Google Accounts via user = users.get_current_user() functionality. I have used this and then I request the user to create account on my app. Is there anyway for the phone app to gain assess to the the user = users.get_current_user() functionality?
I have seen the example of creating a register / login on AI and storing it on TinyDB but the Google UserID is already available on the app engine. How do I access this functionality on the phone app?
with OAuth you can ask the user for permission to view his email address and read that information from his Google profile, see an example how to do that with App Inventor here http://puravidaapps.com/taifunOA.php
