Answer 1

Maybe a bit late to the party here but after more than 4 hours debugging I realized that:

1.- Add an Android client with your signing-certificates fingerprints under the OAuth client IDs list. This is mandatory.

2.- Add the Web application client ID in your code in case your need to get an id token

// ID and basic profile are included in DEFAULT_SIGN_IN
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                            .requestIdToken("YOUR_CLIENT_ID")
                            .requestEmail()
                            .build();

Hope it helps
