如何确认 android 中的应用内购买？

Question

我已经浏览过 Play 结算库 https://developer.android.com/google/play/billing/billing_library_overview 您必须在三天内确认所有购买。未能正确确认购买会导致这些购买被退款。该过程并未明确说明如何确认购买。这是我试过的这是正确的方法吗？提前致谢

@Override


 public void onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases) {
        if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.OK&&purchases!=null){
            Toast.makeText(this, "Purchase Successful", Toast.LENGTH_SHORT).show();
            for(Purchase purchase:purchases){
                handlePurchase(purchase);
            }
        }else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.USER_CANCELED){
            Toast.makeText(this, "Purchase Cancelled", Toast.LENGTH_SHORT).show();
        }else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED){
            Toast.makeText(this, "Already Purchased", Toast.LENGTH_SHORT).show();
        } else{
            Toast.makeText(this, billingResult.getDebugMessage(), Toast.LENGTH_SHORT).show();
        }



    //in handlePurchase()
 if(!purchase.isAcknowledged())
{ 
          AcknowledgePurchaseParams acknowledgePurchaseParams
                    = AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .setDeveloperPayload(purchase.getDeveloperPayload())
                    .build();

            client.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() {
                @Override
                public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
                    if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.OK){
                        Toast.makeText(RemoveAdsActivity.this, "Purchase Acknowledged", Toast.LENGTH_SHORT).show();
                    }
                }
            });
        }

它提到在 link 将近一半时确认购买。根据类型的不同，确认购买的方式也不同。

 private BillingClient mBillingClient = BillingClient.newBuilder(mActivity).setListener(this).build();

//For non-consumables:
mBillingClient.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener());

//For Consumables: 
client.consumeAsync(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);

我发布的 link 包含一个关于如何处理订阅的示例。

更新

以下是确认 non-consumable 和消费品购买的方法，从 non-consumable 开始：

首先，创建 AcknowledgePurchaseParams Class 对象。为此，您需要您应该能够轻松获得的购买令牌，因为您应该在 onPurchasesUpdated 方法或您在 onPurchasesUpdated 之后将购买传递给的其他方法中调用它：

AcknowledgePurchaseParams acknowledgePurchaseParams =
            AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .build();

接下来创建将用作第二个参数的侦听器。这将允许您在确认购买后做一些事情。我在这个例子中显示了一个 snackbar 消息（根据 worbel 的评论，你可以，而且可能应该检查这个 billingResult 的结果）：

AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = new AcknowledgePurchaseResponseListener() {
        @Override
        public void onAcknowledgePurchaseResponse(BillingResult billingResult) {              

            getMessage("Purchase acknowledged");               
        }

    };

创建这些后，使用您的 BillingClient 调用 acknowledgePurchase 方法：

mBillingClient.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);

购买应该被成功确认。

这对 non-consumable 项使用 acknowledgePurchase。

消耗品购买

这很相似，只是它们的名称发生了变化 - 请参阅上例中对它们的解释：

第一个参数-Params-set-up:

ConsumeParams consumeParams = ConsumeParams.newBuilder()
            .setPurchaseToken(purchase.getPurchaseToken())
            .build();

第二个参数-Listener-set-up:

    ConsumeResponseListener consumeResponseListener = new ConsumeResponseListener() {
        @Override
        public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {
            getMessage("Purchase acknowledged");
        }
    }

现在使用您的 BillingClint 和 consumeAsync：

mBillingClient.consumeAsync(consumeParams, consumeResponseListener);

Answer 2

如果您是新手并使用计费库 4.0.0，那么以上代码将不起作用，因为现在所有计费过程都已放在后台线程中，因此请确保您在计费期间不要调用任何 ui 更新代码过程。

使用：

purchase.getSkus.contains("sku here");

而不是

purchase.getSku.equals("sku here");
