나는 BaseGameActivity를 사용 때문에 다른 방법을 찾고 GoogleApiClient.Builder하지만 임을 사용하는 방법이 알고있다.

Answer 1

onCreate 메서드에서 setRequestedClients (BaseGameActivity.CLIENT_GAMES | BaseGameActivity.CLIENT_PLUS);

는 super.conCreate (savedInstanceState) 전에

@Override 
public void onCreate(Bundle savedInstanceState) { 
    // set requested clients (games and cloud save) 
    setRequestedClients(BaseGameActivity.CLIENT_GAMES | 
      BaseGameActivity.CLIENT_PLUS); 

    super.onCreate(savedInstanceState); 


    setContentView(R.layout.activity_leaderboard); 
}
