Google Sign-In requestIdToken returns null

android google-play-services google-signin
JosephK picture JosephK · Dec 5, 2015 · Viewed 12.7k times · Source

I forked this google sample project and ran the android signin.

I set up the options in the google developers console and got a client id, but when running the project the id token comes up null.

The complete code is here
This code requests the id token. 

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.server_client_id))
            .requestEmail()
            .build();

Am I missing something in the setup, any suggestions.

Here is the Log

As I have commented and as Google's documentation, you should use "Web application" type Client Id, instead of "Android" type Client Id.

As the following screenshot:
