Я пытаюсь реализовать метод аутентификации входа в Google с помощью Firebase, но он не работает, и при запуске приложения не возникает ошибка. Когда я нажимаю кнопку, она ничего не делает .Я пытался изменить свой код, но результат тот же.Также я использую жестко запрограммированную строку из файла "google-services.json" из-за распространенной ошибки "Не удается разрешить (default_web_client_id)" *
Вот результат отладки из «Выполнитьвкладка Android Studio.
GoogleLogin.class

//a constant for detecting the login intent result
private static final int RC_SIGN_IN = 234;

//creating a GoogleSignInClient object

//And also a Firebase Auth object

//Then we will get the GoogleSignInClient object from GoogleSignIn class
