Unable to find api GoogleSignIn.silentSignIn

Question

I am following the tutorial found here. But I am unable to find the api: GoogleSignIn.silentSignIn() as mentioned in the doc.

Is it deprecated or removed?

If yes, would anyone please correct the guide.

Answer 1

A correct way

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.server_client_id))
            .requestEmail()
            .build();
GoogleSignInClient googleSignInClient = GoogleSignIn.getClient(this, gso);
googleSignInClient.silentSignIn().addOnCompleteListener(this, new OnCompleteListener<GoogleSignInAccount>() {
    @Override
    public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
        handleSignInResult(task);
    }
});

That's a mistake in the example, the method is declared in Auth.GoogleSignInApi. See the references.
