应用内购订阅优惠不显示问题

问题描述

处理应用内购订阅优惠时出现异常，其余功能均正常。本人是符合优惠条件的新用户（从未购买过该订阅），但启动支付流程后，界面未显示折扣价格或优惠详情。

查询产品代码

ImmutableList<QueryProductDetailsParams.Product> productList = ImmutableList.of(
        //Product 1
        QueryProductDetailsParams.Product.newBuilder()
                .setProductId(BaseActivity.ONE_MONTH)
                .setProductType(BillingClient.ProductType.SUBS)
                .build(),
        //Product 2
        QueryProductDetailsParams.Product.newBuilder()
                .setProductId(BaseActivity.ONE_YEAR)
                .setProductType(BillingClient.ProductType.SUBS)
                .build()
);
QueryProductDetailsParams queryProductDetailsParams = QueryProductDetailsParams.newBuilder()
        .setProductList(productList)
        .build();

billingClient.queryProductDetailsAsync(queryProductDetailsParams, new ProductDetailsResponseListener() {
    @Override
    public void onProductDetailsResponse(@NonNull BillingResult billingResult, @NonNull List<ProductDetails> list) {
      this.productDetailsList = list;
    }
});

启动支付流程代码

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

billingClient.launchBillingFlow(this, billingFlowParams);
