將優惠存入Google電子錢包

Question

在我的應用中，我需要從我的應用向Google電子錢包實施保存優惠。我發現這個教程：https://developers.google.com/wallet/objects/savetowalletnative#4_create_an_object，但是當我試圖實現它時，我遇到了一個問題。有代碼從頁：

OfferWalletObject wob = OfferWalletObject 
     .newBuilder()... 

但我的環境說，類沒有這種方法。在此頁面中沒有關於此方法的任何信息：https://developer.android.com/reference/com/google/android/gms/wallet/OfferWalletObject.html

有人可以幫助解決這個問題，或者談談其他方法以在Google電子錢包中保存優惠。
