【中文标题】Google Play 结算库 3.0+ - 恢复购买【英文标题】：Google Play Billing Library 3.0+ - Restore purchase 【发布时间】：2021-05-06 15:43:31 【问题描述】：借助 Google Play 结算库 v3.0+，我们有了新的购买流程，一切都在这里得到了完美的解释： Google Play Billing
在旧版本的库中，我们将恢复如下内容：
bp = new BillingProcessor(this, MERCHANT_ID, new BillingProcessor.IBillingHandler()
@Override
public void onProductPurchased(@NonNull String productId, @Nullable TransactionDetails details)
String orderId = details.purchaseInfo.purchaseData.productId;
// we then compare the orderID with the SKU and see if the user purchased the item,
// however in the new version of the library there is nothing about restore
但是，文档中没有关于恢复购买的任何内容？
例如，我们有一个用例，您有一个有效的订阅和一个您购买的 IAP 产品。您删除该应用程序并重新安装它。您如何恢复订阅和该 IAP 产品？
【问题讨论】：
【参考方案1】：BillingProcessor 和 onProductPurchased 似乎不是 Play Billing Library（也不是 AIDL）的一部分，它更像是 anjlab 实现的包装类（https://github.com/anjlab/android-inapp-billing-v3） 为了满足您的需求，我认为queryPurchases 和queryPurchaseHistoryAsync 可以提供帮助。
【讨论】：
【参考方案2】：基本上 queryPurchaseHistoryAsync 可以完成这项工作，只是要小心传递 SKU TYPE（inapp 或 subs）。
我的实现：
fun restorePurchaseInApp()
bp.queryPurchaseHistoryAsync("inapp", this)
fun restorePurchaseInSubs()
bp.queryPurchaseHistoryAsync("subs", this)
// bp is BillingClient
// the class should implement PurchaseHistoryResponseListener
override fun onPurchaseHistoryResponse(
p0: BillingResult,
p1: MutableList<PurchaseHistoryRecord>?
)
if (p1 != null)
Log.d("TMS", "onPurchaseHistoryResponse: " + p1.size)
if (p1 != null)
for (item in p1)
Log.d("TMS", "onPurchaseHistoryResponse sku: " + item.sku)
Log.d("TMS", "onPurchaseHistoryResponse signature: " + item.signature)
Log.d("TMS", "onPurchaseHistoryResponse purchaseToken: " + item.purchaseToken)
Log.d("TMS", "onPurchaseHistoryResponse purchaseTime: " + item.purchaseTime)
在那里你会得到购买的物品，就是这样:)。我希望这会有所帮助，因为我浪费了很多时间来弄清楚这么简单的事情，而文档实现中没有提到这一点。

【参考方案3】：使用Github 上提供的 Google InApp 结算库。
Android In-App Billing API 的简单实现。
dependencies
implementation 'com.github.moisoni97:google-inapp-billing:1.0.5'
◆ 创建一个BillingConnector 类的实例。构造函数将采用 2 个参数：
● Context
● License key from *Play Console*
billingConnector = new BillingConnector(this, "license_key")
.setConsumableIds(consumableIds)
.setNonConsumableIds(nonConsumableIds)
.setSubscriptionIds(subscriptionIds)
.autoAcknowledge()
.autoConsume()
.enableLogging()
.connect();
◆ 实现监听器来处理事件结果和错误：
billingConnector.setBillingEventListener(new BillingEventListener()
@Override
public void onProductsFetched(@NonNull List<SkuInfo> skuDetails)
/*Provides a list with fetched products*/
@Override
public void onPurchasedProductsFetched(@NonNull List<PurchaseInfo> purchases)
/*Provides a list with fetched purchased products*/
@Override
public void onProductsPurchased(@NonNull List<PurchaseInfo> purchases)
/*Callback after a product is purchased*/
@Override
public void onPurchaseAcknowledged(@NonNull PurchaseInfo purchase)
/*Callback after a purchase is acknowledged*/
/*
* Grant user entitlement for NON-CONSUMABLE products and SUBSCRIPTIONS here
*
* Even though onProductsPurchased is triggered when a purchase is successfully made
* there might be a problem along the way with the payment and the purchase won't be acknowledged
*
* Google will refund users purchases that aren't acknowledged in 3 days
*
* To ensure that all valid purchases are acknowledged the library will automatically
* check and acknowledge all unacknowledged products at the startup
* */
@Override
public void onPurchaseConsumed(@NonNull PurchaseInfo purchase)
/*Callback after a purchase is consumed*/
/*
* CONSUMABLE products entitlement can be granted either here or in onProductsPurchased
* */
@Override
public void onBillingError(@NonNull BillingConnector billingConnector, @NonNull BillingResponse response)
/*Callback after an error occurs*/
switch (response.getErrorType())

//TODO - client is not ready yet
break;
case CLIENT_DISCONNECTED:
//TODO - client has disconnected
break;
case SKU_NOT_EXIST:
//TODO - sku does not exist
break;
case CONSUME_ERROR:
//TODO - error during consumption
break;
case ACKNOWLEDGE_ERROR:
//TODO - error during acknowledgment
break;
case ACKNOWLEDGE_WARNING:
/*
* This will be triggered when a purchase can not be acknowledged because the state is PENDING
* A purchase can be acknowledged only when the state is PURCHASED
*
* PENDING transactions usually occur when users choose cash as their form of payment
*
* Here users can be informed that it may take a while until the purchase complete
* and to come back later to receive their purchase
* */
//TODO - warning during acknowledgment

case FETCH_PURCHASED_PRODUCTS_ERROR:
//TODO - error occurred while querying purchased products

case DEVELOPER_ERROR:

case ERROR:

case ITEM_ALREADY_OWNED:
//TODO - failure to purchase since item is already owned
break;
case ITEM_NOT_OWNED:
//TODO - failure to consume since item is not owned
break;
);
开始购买
● 购买非消耗品/消耗品：
billingConnector.purchase(this, "sku_id");
● 购买订阅：
billingConnector.subscribe(this, "sku_id");
● 取消订阅：
billingConnector.unsubscribe(this, "sku_id");
