        AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), null);
        mAuth.signInWithCredential(credential).addOnCompleteListener(this, task -> {
            if(task.isSuccessful()) {
                mGoogleSignInClient.signOut();
                updateUI();
            } else {
                Toast.makeText(this, "Something went wrong.", Toast.LENGTH_SHORT).show();

        });
    } catch (ApiException e) {
        Log.w("SignIn Failed", "signInResult:failed code=" + e.getStatusCode());
        updateUI(null);
    }
