【问题描述】：

我正在使用 Google 的结算库在我的应用中进行订阅。

~~ 3 天后，google play 退还了我用户的所有订阅费用，这是为什么呢？

一些带有活动的代码，用于订阅：

    private var billingClient: BillingClient? = null
    private val purchasesUpdateListener = PurchasesUpdatedListener { billingResult, purchases ->
        val isSuccessResult = billingResult.responseCode == BillingClient.BillingResponseCode.OK
        val hasPurchases = !purchases.isNullOrEmpty()
        if (isSuccessResult && hasPurchases) {
            purchases?.forEach(::confirmPurchase)
            viewModel.hasSubscription.value = true
        }
    }

    private fun confirmPurchase(purchase: Purchase) {
        val consumeParams = ConsumeParams.newBuilder()
            .setPurchaseToken(purchase.purchaseToken)
            .build()
        billingClient?.consumeAsync(consumeParams) { billingResult, _ ->
            if (billingResult.responseCode != BillingClient.BillingResponseCode.OK) {
                //all done
            }
        }
    }
 override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
   
        billingClient = BillingClient.newBuilder(this)
            .setListener(purchasesUpdateListener)
            .enablePendingPurchases()
            .build()

        connectToBillingService()
    }

    private fun connectToBillingService() {
        billingClient?.startConnection(this)
    }

    private fun getPurchases(): List<Purchase> {
        val purchasesResult = billingClient?.queryPurchases(BillingClient.SkuType.SUBS)
        return purchasesResult?.purchasesList.orEmpty()
    }

    override fun onBillingSetupFinished(result: BillingResult) {
        if (result.responseCode == BillingClient.BillingResponseCode.OK) {
            updateSkuMap()
        }
    }
}

【解决方案1】：

因为您使用的是 Play 结算库 2.0 或更高版本。从 Play Billing Library 2.0 开始，所有购买必须在三天内得到确认。未能正确确认购买将导致购买被退款。查看Play Billing Library v2.0 release notes 和Processing Purchases 了解更多详情。

【解决方案2】：

在您的代码中，您使用consumeAsync() 确认购买，

这是一次性消耗品的正确方式，因为consumeAsync()会自动为您确认。

但是对于订阅，您应该使用client.acknowledgePurchase() 方法而不是consumeAsync()

这是 Kotlin 的示例

val client: BillingClient = ...
val acknowledgePurchaseResponseListener: AcknowledgePurchaseResponseListener = ...

suspend fun handlePurchase() {
    if (purchase.purchaseState === PurchaseState.PURCHASED) {
        if (!purchase.isAcknowledged) {
            val acknowledgePurchaseParams = AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.purchaseToken)
            val ackPurchaseResult = withContext(Dispatchers.IO) {
               client.acknowledgePurchase(acknowledgePurchaseParams.build())
            }
        }
     }
}
