Ahorro de oferta en Google Wallet

En mi aplicación, necesito implementar una oferta de ahorro de mi aplicación a Google Wallet. Encontré este tutorial: https://developers.google.com/wallet/objects/savetowalletnative#4_create_an_object , pero cuando intenté implementarlo, encontré un problema. Hay un código de la página:

OfferWalletObject wob = OfferWalletObject .newBuilder()...

Pero mi entorno dice que la clase no tiene este método. No hay nada escrito sobre este método en esta página: https://developer.android.com/reference/com/google/android/gms/wallet/OfferWalletObject.html

¿Puede alguien ayudar a resolver este problema o decir acerca de otro método para guardar la oferta en la cartera de Google.

He integrado Google Wallet correctamente, desde este video. Enlazar
