In-app billing acknowledgePurchase 问题 [使用 google play 应用内计费库]

Question

我是 android 新手，第一次尝试实现应用内结算。

我正在使用 google play 应用内库。 https://developer.android.com/google/play/billing/billing_library_overview

我想实现消耗品应用内购买。我正在使用“android.test.purchased”保留 id 进行测试。我可以加载 skuDetails 并成功购买并成功消费购买

这是我的 handlePurchase 方法，带有 consumeAsync

void handlePurchase(Purchase purchase) {



BillingClient client = BillingClient.newBuilder(NewAdActivity.this)
        .enablePendingPurchases() 
        .setListener(this)
        .build();


if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
     System.out.println("item successfully purchased");


        if (!purchase.isAcknowledged()) {


                    ConsumeParams consumeParams = ConsumeParams.newBuilder()
                        .setPurchaseToken(purchase.getPurchaseToken())
                        .setDeveloperPayload(purchase.getDeveloperPayload())
                        .build();


                     ConsumeResponseListener consumeResponseListener = new ConsumeResponseListener() {
                    @Override
                    public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {
                          if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && purchaseToken != null) {
                              System.out.println("SUCCESSFULLY consumed PURCHASE");
                              providecontent();

                           } 
                        else { 
                              System.out.println("FAILED TO consume:”);
                            }

                    }

                };

                client.consumeAsync(consumeParams, consumeResponseListener); 



        }

    }



}

我消费购买时是否也确认购买？我是否需要在 purchase.originalJson 中手动设置 "acknowledged":true ？

我的代码是否可以正确消费购买的商品？或者我需要在消费之前添加一个单独的确认购买。

请回复。任何帮助都非常感谢。

谢谢。

Answer 1

对于消耗品，您想使用 consumeAsync()。对于非消耗品的产品，您需要使用 acknowledgePurchase()。有关在您的应用中确认购买的更多信息，请查看官方文档：https://developer.android.com/google/play/billing/billing_library_overview#acknowledge

欢迎来到stackoverflow！

您错误地使用了consumeAsync()，要确认购买，您应该致电acknowledgePurchase()。

consumeAsync()删除购买的物品，例如如果购买允许用户玩10次并且他使用了所有这些，那么你会调用consumeAsync()让用户再次购买物品

一个例子：

  if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
            // Grant entitlement to the user.
            boolean signOk = verifyPurchaseSignature(purchase.getOriginalJson(), purchase.getSignature());
            if (!signOk) {
                // Alert the user about wrong signature
                return;
            } else if (!purchase.isAcknowledged()) {
                AcknowledgePurchaseParams acknowledgePurchaseParams =
                        AcknowledgePurchaseParams.newBuilder()
                                .setPurchaseToken(purchase.getPurchaseToken())
                                .build();
                billingClient.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() {
                    @Override
                    public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
                        //Give thanks for the purchase                        

                    }
                });
            }
        }
