安卓计费；如何解决“找不到您尝试购买的商品”

Question

由于最近对 Google Billing 库和开发者控制台的所有更改，很难应用 2014 年的答案，所以我再次发布关于这个主题的帖子，希望找到一个现代的答案。

我正在使用 Google 结算库 2.2.0

问题：

---

我已设置许可证：

---

我还设置了许可证测试：

---

我还向内部测试轨道发布了一个发布版本（使用发布证书签名）：

---

相关代码示例：

private final String SKU_TEST_PROD_1YR = "test_prod_id_1_year";
private final String SKU_TEST_PROD_6MN = "test_prod_id_6_month";
private final String SKU_TEST_PROD_1MN = "test_prod_id_1_month";
private BillingClient billingClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    List<String> iapProdIdList = Arrays.asList(SKU_TEST_PROD_1YR, SKU_TEST_PROD_6MN, SKU_TEST_PROD_1MN);
    setupBillingClient(this, iapProdIdList);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    billingClient.endConnection();
}

private void setupBillingClient(Context context, List<String> iapProdList) {
    billingClient = BillingClient.newBuilder(context).setListener(this).build();
    billingClient.startConnection(new BillingClientStateListener() {
        @Override
        public void onBillingSetupFinished(BillingResult billingResult) {
            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                loadAllSubscriptionProductIdDetails(iapProdList);
            }
        }

        @Override
        public void onBillingServiceDisconnected() { }
    });
}

private void loadAllSubscriptionProductIdDetails(List<String> iapProdList) {
    if (billingClient.isReady()) {
        SkuDetailsParams params = SkuDetailsParams.newBuilder().setSkusList(iapProdList).setType(BillingClient.SkuType.SUBS).build();

        billingClient.querySkuDetailsAsync(params, (billingResult, prodDetailList) -> {
            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && !prodDetailList.isEmpty()) {

                for (SkuDetails prodDetail : prodDetailList) {

                    String productSku = prodDetail.getSku();

                    switch(productSku) {
                        case SKU_TEST_PROD_1YR : {
                            final BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder().setSkuDetails(prodDetail).build();
                            buttonIap1Yr.setOnClickListener(v -> {
                                // trigger purchase - Google needs the parent activity to overlay with their UI
                                billingClient.launchBillingFlow(this, billingFlowParams);
                            });
                            break;
                        }
                        case SKU_TEST_PROD_6MN : {
                            final BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder().setSkuDetails(prodDetail).build();
                            buttonIap6mth.setOnClickListener(v -> {
                                // trigger purchase - Google needs the parent activity to overlay with their UI
                                billingClient.launchBillingFlow(this, billingFlowParams);
                            });
                            break;
                        }
                        case SKU_TEST_PROD_1MN : {
                            final BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder().setSkuDetails(prodDetail).build();
                            buttonIap1mth.setOnClickListener(v -> {
                                // trigger purchase - Google needs the parent activity to overlay with their UI
                                billingClient.launchBillingFlow(this, billingFlowParams);
                            });
                            break;
                        }
                        default :
                            Toast.makeText(this, "Did not find Product in-app: "+ productSku, Toast.LENGTH_SHORT).show();
                    }
                }//end of FOR
            }//end of IF
        });
    } else {
        Toast.makeText(this, "billingClient is NOT ready", Toast.LENGTH_SHORT).show();
    }
}

@Override
public void onPurchasesUpdated(BillingResult billingResult, List<Purchase> list) {

    if (billingResult != null && list != null) {
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
            for (Purchase purchase : list) {
                if(!purchase.isAcknowledged()) acknowledgePurchase(purchase.getPurchaseToken());
            }
        }
        else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
            Toast.makeText(this, "User Canceled", Toast.LENGTH_SHORT).show();
        }
        else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED) {
            Toast.makeText(this, "Already Purchased", Toast.LENGTH_SHORT).show();
        }
    }
}

private void acknowledgePurchase(String purchaseToken) {
    AcknowledgePurchaseParams params = AcknowledgePurchaseParams.newBuilder().setPurchaseToken(purchaseToken).build();
    billingClient.acknowledgePurchase(params, billingResult -> {
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
            Toast.makeText(this, "Purchase Acknowledged", Toast.LENGTH_SHORT).show();
        }
    });
}

当我点击任何 [购买订阅] 按钮时，billingClient.launchBillingFlow(this, billingFlowParams); 被正确触发并且 SKU 正确。

据我所知，所有开发控制台均已正确设置。 我想向我的经理演示 IAP，但是，“找不到您尝试购买的商品”让我的风格受挫！ 我做错了什么？

Answer 1

我在问题中发布的代码功能齐全。由于开发者控制台配置，问题是 100%：

修复它：

1) 将应用升级为 Alpha，最低要求（内部测试轨道不起作用！）

2) 点击 Alpha 轨道上的 [管理] 并将选择加入链接通过电子邮件发送给您的测试人员

3) 您的测试人员会说“当我点击此链接时，Play 商店说找不到该应用”。告诉他们放松 30 分钟 - Google 控制台需要 30 分钟来处理这种复杂性。

让他们下载早期版本，然后 IAP 突然起作用了！

Answer 2

我认为您的loadAllSubscriptionProductIdDetails() 方法设计错误。

您只需在用户点击时调用querySkuDetailsAsync()，setSkusList() 参数中只有一个项目，即要购买的项目，然后：

  @Override
  public void onSkuDetailsResponse(BillingResult billingResult, List<SkuDetails> skuDetailsList) {
       if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && skuDetailsList.size() > 0) {
                    BillingFlowParams flowParams = BillingFlowParams.newBuilder()
                            .setSkuDetails(skuDetailsList.get(0))
                            .build();

                    billingClient.launchBillingFlow(activity, flowParams);

            }

      }
