android - 将优惠保存到 Google 电子钱包

Question

在我的应用中，我需要实现从我的应用到 Google 电子钱包的储蓄优惠。我找到了这个教程:Developer Documentation- wallet ，但是当我尝试实现它时，我遇到了一个问题。页面中有代码:

OfferWalletObject wob = OfferWalletObject
        .newBuilder()...

但是我的环境说那个类没有这个方法。此页面中没有任何关于此方法的说明:Developer Reference Document

有人可以帮忙解决这个问题，或者说一下在谷歌钱包中保存优惠的其他方法。

通过此视频，我已成功集成 Google 电子钱包。 Link
