Google Pay国际版开发
一、官网地址（科学上网）

以下是相关的官方文档和链接： - 官方对接文档：[https://developers.google.com/pay/api/android/overview](https://developers.google.com/pay/api/android/overview) - Stripe对接Google Pay：[https://stripe.com/docs/google-pay](https://stripe.com/docs/google-pay) - Stripe验证支付：[https://stripe.com/docs/payments/accept-a-payment?integration=elements](https://stripe.com/docs/payments/accept-a-payment?integration=elements) - Stripe管理后台：[https://dashboard.stripe.com/dashboard](https://dashboard.stripe.com/dashboard)
二、接入流程

Google Pay 是谷歌推出的一款支付服务（使用了 Stripe 作为支付网关）。(google pay api)(google pay是什么软件)-第1张图片-谷歌商店上架
三、主要流程

1、服务器请求orderId

2、调用Google Pay

3、通过Stripe完成支付

4、服务器完成验证

四、主要代码实现（1、4主要是服务器流程，以下主要是2、3流程）

项目配置
在build.gradle中添加以下依赖项：
```
implementation 'com.google.android.gms:play-services-wallet:18.1.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.stripe:stripe-android:16.0.1'
```

在AndroidManifest.xml的application标签下添加以下代码：
```xml

```

调用Google Pay。 ```java
@RequiresApi(api = Build.VERSION_CODES.N)
private void payWithGoogle(double price) {
    if (paymentsClient == null) {
        paymentsClient = createPaymentsClient(mActivity);
    }
    
    // 主要是Google Pay一些参数设置
    Optional paymentDataRequestJson = createPaymentDataRequest(price);
    
    if (!paymentDataRequestJson.isPresent()) {
        return;
    }
    
    PaymentDataRequest request = PaymentDataRequest.newBuilder()
            .setTransactionInfo(TransactionInfo.newBuilder()
                    .setTotalPriceStatus(WalletConstants.TOTAL_PRICE_STATUS_FINAL)
                    .setTotalPrice(String.valueOf(price))
                    .setCurrencyCode(USD)
                    .build())
            .build();
}
``` @RequiresApi(api = Build.VERSION_CODES.N)

        // Detailed information about authorizing the transaction based on whether the user agrees to it. Includes total price and price status.
        paymentDataRequest.put(transactionInfo, getTransactionInfo(priceCents));
        // Merchant information
        paymentDataRequest.put(merchantInfo, getMerchantInfo());
        paymentDataRequest.put(shippingAddressRequired, false);
        paymentDataRequest.put(emailRequired, false);
