Android Play 商店订阅计费不会触发任何操作

Question

我已经成功实现了应用内购买流程，现在我正在尝试切换到订阅模式，但是 makePurchase() 方法有问题，它没有打开用户付款的窗口。

private void createPurchaseFlow(String productID, PostTaskListener<String> callback)
{
    Print.e("createPurchaseFlow productID: "+ productID);
    PurchasesUpdatedListener purchasesUpdatedListener = new PurchasesUpdatedListener()
    {
        @Override
        public void onPurchasesUpdated(@NonNull BillingResult billingResult,
                                       List<Purchase> purchases)
        {
            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK
                    && purchases != null)
            {
                for (Purchase purchase : purchases)
                {
                    consumePurchase(purchase,productID,callback);
                }
            }
            else if (billingResult.getResponseCode() ==
                    BillingClient.BillingResponseCode.USER_CANCELED)
            {
                callback.onPostTask("User Canceled");
                Print.e("onPurchasesUpdated: Purchase Canceled");
            }
            else
            {
                callback.onPostTask("Purchase Failed");
                Print.e("onPurchasesUpdated: Error");
            }
        }
    };

    billingClient = BillingClient.newBuilder(activity)
            .setListener(purchasesUpdatedListener)
            .enablePendingPurchases()
            .build();

    billingClient.startConnection(new BillingClientStateListener()
    {
        @Override
        public void onBillingSetupFinished(@NonNull BillingResult billingResult)
        {
            if (billingResult.getResponseCode() ==
                    BillingClient.BillingResponseCode.OK)
            {
                Print.e("OnBillingSetupFinish connected");
                queryProduct(productID,callback);
            }
            else
            {
                Print.e("OnBillingSetupFinish failed");
            }
        }

        @Override
        public void onBillingServiceDisconnected()
        {
            // Try to restart the connection on the next request to
            // Google Play by calling the startConnection() method.
            Print.e("onBillingServiceDisconnected");
            callback.onPostTask("Billing Service Disconnected");
        }
    });
}

private void queryProduct(String subscriptionID, PostTaskListener<String> callback)
{
    QueryProductDetailsParams queryProductDetailsParams =
            QueryProductDetailsParams.newBuilder()
                    .setProductList(
                            ImmutableList.from(
                                    QueryProductDetailsParams.Product.newBuilder()
                                            .setProductId(subscriptionID)
                                            .setProductType(
                                                    BillingClient.ProductType.SUBS)
                                            .build()))
                    .build();

    billingClient.queryProductDetailsAsync(
            queryProductDetailsParams,
            new ProductDetailsResponseListener()
            {
                @Override
                public void onProductDetailsResponse(@NonNull BillingResult billingResult,
                                                     @NonNull List<ProductDetails> productDetailsList)
                {
                    if (!productDetailsList.isEmpty())
                    {
                        Print.e("onProductDetailsResponse");
                        ProductDetails productDetails = productDetailsList.get(0);
                        makePurchase(productDetails);
                    }
                    else
                    {
                        callback.onPostTask(null);
                        Print.e("onProductDetailsResponse: No subscriptions");
                    }
                }
            }
    );
}

private void makePurchase(ProductDetails productDetails)
{
    Print.e("makePurchase: " + productDetails.getName());

    List<BillingFlowParams.ProductDetailsParams> productDetailsParamsList = ImmutableList.from(
            BillingFlowParams.ProductDetailsParams.newBuilder()
                    .setProductDetails(productDetails)
                    .build()
    );

    BillingFlowParams billingFlowParams =
            BillingFlowParams.newBuilder()
                    .setProductDetailsParamsList(productDetailsParamsList)
                    .build();

    BillingResult billingResult = billingClient.launchBillingFlow(activity, billingFlowParams);


    Print.e("billingResult: " + billingResult.getResponseCode() +
            " getDebugMessage: " +  billingResult.getDebugMessage() +
            " toString: " +  billingResult.toString());
}

此行后不打印消息

BillingResult billingResult = billingClient.launchBillingFlow(activity, billingFlowParams);

所以我放置了断点，代码一直运行到这段代码：

        List<BillingFlowParams.ProductDetailsParams> productDetailsParamsList = ImmutableList.from(
            BillingFlowParams.ProductDetailsParams.newBuilder()
                    .setProductDetails(productDetails)
                    .build()
    );

然后什么也没有发生，没有错误，零日志。这是怎么回事？

好的，所以我需要进行此更改：

List<BillingFlowParams.ProductDetailsParams> productDetailsParamsList = ImmutableList.from(
            BillingFlowParams.ProductDetailsParams.newBuilder()
                    .setOfferToken(productDetails.getSubscriptionOfferDetails().get(0).getOfferToken())
                    .setProductDetails(productDetails)
                    .build()
    );
