What is diff between requestIdToken and requestServerAuthCode in google singnin : <p>I am not able to differentiate between these two: requestIdToken and requestServerAuthCode, when we signin with google api from android device.</p>

<p>My requirement is to provide option for users to login in android device, and after login sync data to my server.
Server need to validate logged in user request from android device. I am thinking to use "requestIdToken".
On the server side i am using google client library to fetch user info from requestIdToken.</p>
