在Android中完全集成谷歌钱包

Question

我开发了一个具有支付功能的应用程序，所以我使用谷歌钱包来获得付款所以我做了研究，我得到了一些教程Link的链接所以我可以这样的代码

  WalletFragmentStyle walletFragmentStyle = new WalletFragmentStyle()
            .setBuyButtonText(BuyButtonText.BUY_WITH_GOOGLE)
            .setBuyButtonWidth(Dimension.MATCH_PARENT);

    WalletFragmentOptions walletFragmentOptions = WalletFragmentOptions.newBuilder()
            .setEnvironment(WalletConstants.ENVIRONMENT_SANDBOX)
            .setFragmentStyle(walletFragmentStyle)
            .setTheme(WalletConstants.THEME_HOLO_LIGHT)
            .setMode(WalletFragmentMode.BUY_BUTTON)
            .build();

    mWalletFragment = SupportWalletFragment.newInstance(walletFragmentOptions);

    MaskedWalletRequest maskedWalletRequest =
            WalletUtil.createMaskedWalletRequest(Constant.ITEMS_FOR_SALE[0]);
    WalletFragmentInitParams.Builder startParamsBuilder = WalletFragmentInitParams.newBuilder()
            .setMaskedWalletRequest(maskedWalletRequest)
            .setMaskedWalletRequestCode(REQUEST_CODE_MASKED_WALLET)
            .setAccountName("abc");

    mWalletFragment.initialize(startParamsBuilder.build());

    getSupportFragmentManager().beginTransaction()
            .replace(R.id.dynamic_wallet_button_fragment, mWalletFragment)
            .commit();

但我不认为这实际上有效，这看起来像假人所以我想整合实际的支付流程与谷歌钱包所以任何人都可以建议我代码

非常感谢你。
