如何优雅的集成Google pay到你的项目中
官方集成文档 官方集成文档 官方集成文档
第一步：
java
dependencies {
def billing_version = "3.0.0"
implementation 'com.android.billingclient:billing:$billing_version'
}
kotlin
dependencies {
def billing_version = "3.0.0"
implementation 'com.android.billingclient:billing-ktx:$billing_version'
}
第二部：
private PurchasesUpdatedListener purchaseUpdateListener = new PurchasesUpdatedListener() {
@Override
void onPurchasesUpdated(BillingResult billingResult, List<Purchase> purchases) {
// To be implemented in a later section.
}
};
private BillingClient billingClient = BillingClient.newBuilder(activity)
.setListener(purchasesUpdatedListener)
.enablePendingPurchases()
.build();
第三部：
billingClient.startConnection(new BillingClientStateListener() {
@Override
public void onBillingSetupFinished(BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingResponseCode.OK) {
// The BillingClient is ready. You can query purchases here.
//链接成功
}
}
@Override
public void onBillingServiceDisconnected() {
// Try to restart the connection on the next request to
// Google Play by calling the startConnection() method.
// 链接失败触发，触发重连机制
}
});
第四部： 请求自己服务器，拿到对应的商品列表，这里拿到的商品列表要和Google后台配置的商品列表ID一致。
List<String> skuList = new ArrayList<> ();
skuList.add("premium_upgrade");
SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
params.setSkusList(skuList).setType(SkuType.INAPP);
billingClient.querySkuDetailsAsync(params.build(),
new SkuDetailsResponseListener() {
@Override
public void onSkuDetailsResponse(BillingResult billingResult,
List<SkuDetails> skuDetailsList) {
// Process the result.
}
});
第五步： 调起Google 支付界面
// An activity reference from which the billing flow will be launched.
Activity activity = ...;
// Retrieve a value for "skuDetails" by calling querySkuDetailsAsync().
BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder()
.setSkuDetails(skuDetails)
.build();
int responseCode = billingClient.launchBillingFlow(activity, billingFlowParams).getResponseCode();
// Handle the result.
此处说明你的支付已经完成，回调到你最开始初始化的onPurchasesUpdated方法里边。
if (billingResult.getResponseCode() == BillingResponseCode.OK
&& purchases != null) {
for (Purchase purchase : purchases) {
handlePurchase(purchase);
}
} else if (billingResult.getResponseCode() == BillingResponseCode.USER_CANCELED) {
// Handle an error caused by a user cancelling the purchase flow.
} else {
// Handle any other error codes.
}
第六步： Google 支付分为两个部分，购买和验证，比如我们的产品是虚拟货币，是一次性消耗产品，使用下边方法去验证消耗。 最好的处理方法是请求后台服务器，让后台做一个验证，然后我们再去验证消费（保证安全性）
void handlePurchase(Purchase purchase) {
// Purchase retrieved from BillingClient#queryPurchases or your PurchasesUpdatedListener.
Purchase purchase = ...;
// Verify the purchase.
// Ensure entitlement was not already granted for this purchaseToken.
// Grant entitlement to the user.
ConsumeParams consumeParams =
ConsumeParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.build();
ConsumeResponseListener listener = new ConsumeResponseListener() {
@Override
public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {
if (billingResult.getResponseCode() == BillingResponseCode.OK) {
// Handle the success of the consume operation.
}
}
};
billingClient.consumeAsync(consumeParams, listener);
}
因为网络原因可能会出现，掉单的问题，所以就会出现补单的逻辑。
调起支付之前
BillingResult billingResult = billingClient.launchBillingFlow(this, billingFlowParams);
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED) {
queryHistory();
}
/**
* 查询历史记录，有没校验的开始支付验证流程
*/
public void queryHistory() {
if (billingClient == null) {
return;
}
//google消费失败的补单
List<Purchase> purchases = billingClient.queryPurchases(BillingClient.SkuType.INAPP).getPurchasesList();
if (purchases != null && !purchases.isEmpty()) {
for (Purchase purchase : purchases) {
handlePurchase(purchase);
return;
}
}
}
