我在基于官方sample project的应用程序中使用Google Play应用程序内。
代码A用于处理非消耗性产品，当我使用com.android.billingclient:billing-ktx:3.0.3启动它时，它工作得很好。
在我将项目从Google Play计费库3升级到4后，我发现代码purchase.sku不起作用，所以我必须将其替换为purchase.skus。
purchase.skus的代码可以编译到com.android.billingclient:billing-ktx:4.0.0，但我无法获得正确的订单，测试购买3分钟后退款，似乎Google Play不承认购买。
当我将Google Play计费库3升级到4时，如何修复代码A？

代码A

private fun processPurchases(purchasesResult: Set<Purchase>) {
        val validPurchases = HashSet<Purchase>(purchasesResult.size)
        purchasesResult.forEach { purchase ->
            if (purchase.purchaseState == Purchase.PurchaseState.PURCHASED) {
                if (purchase.sku.equals(purchaseItem)) {
                //if (purchase.skus.equals(purchaseItem)) {     //sku -> skus  in 4.0
                    if (isSignatureValid(purchase)) {
                        validPurchases.add(purchase)
                    }
                }
            } else if (purchase.purchaseState == Purchase.PurchaseState.PENDING) {
                Log.d(LOG_TAG, "Received a pending purchase of SKU: ${purchase.sku}")
                // handle pending purchases, e.g. confirm with users about the pending
                // purchases, prompt them to complete it, etc.
                mContext.toast(R.string.msgOrderPending)

            } else {
                mContext.toast(R.string.msgOrderError)
            }
        }

        acknowledgeNonConsumablePurchasesAsync(validPurchases.toList())
    }
