/**
 * Example base class for games. This implementation takes care of setting up
 * the GamesClient object and managing its lifecycle. Subclasses only need to
 * override the @link{#onSignInSucceeded} and @link{#onSignInFailed} abstract
 * methods. To initiate the sign-in flow when the user clicks the sign-in
 * button, subclasses should call @link{#beginUserInitiatedSignIn}. By default,
 * this class only instantiates the GamesClient object. If the PlusClient or
 * AppStateClient objects are also wanted, call the BaseGameActivity(int)
 * constructor and specify the requested clients. For example, to request
 * PlusClient and GamesClient, use BaseGameActivity(CLIENT_GAMES | CLIENT_PLUS).
 * To request all available clients, use BaseGameActivity(CLIENT_ALL).
 * Alternatively, you can also specify the requested clients via
 * @link{#setRequestedClients}, but you must do so before @link{#onCreate}
 * gets called, otherwise the call will have no effect.
