Google Play 结算库 2.0 版 - .setSkuDetails(skuDetails)

Question

如何在调用时在 java 中设置 .setSkuDetails(skuDetails)

BillingFlowParams flowParams = BillingFlowParams.newBuilder()
        .setSkuDetails(skuDetails)
        .build();
int responseCode = billingClient.launchBillingFlow(flowParams);

我搜索了整个谷歌，但没有找到任何正确和完整的实现，请有人通过提供具有所有必要功能的完整过程来帮助我，因为我只找到 library1.0 示例或 Kotlin 或不完整，我想要 java

请帮帮我

Answer 1

这是完整的实现。

如需进一步参考，请参阅文档：https://developer.android.com/google/play/billing/billing_library_overview

String ITEM_SKU_diamond_500 = "diamond_500";
BillingClient billingClient;
AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener;
String premiumUpgradePrice = "";

1：必须使用BillingClient.Builder 创建计费客户端。

billingClient = BillingClient.newBuilder(this)
                .enablePendingPurchases()
                .setListener(this).build();

2：创建billingClient 后启动billingClient 连接

        billingClient.startConnection(new BillingClientStateListener() {
            @Override
            public void onBillingSetupFinished(BillingResult billingResult) {
                if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {

                    List<String> skuList = new ArrayList<>();
                    skuList.add(ITEM_SKU_diamond_500);
                    final SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
                    params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP);

3：建立连接成功后，调用billingClient的querySkuDetailsAsync方法异步获取SKU的详细信息。

                    billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {
                        @Override
                        public void onSkuDetailsResponse(BillingResult billingResult, List<SkuDetails> skuDetailsList) {
                            if (skuDetailsList != null && billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                                for (SkuDetails skuDetails : skuDetailsList) {
                                    String sku = skuDetails.getSku();
                                    String price = skuDetails.getPrice();

                                    final BillingFlowParams params = BillingFlowParams.newBuilder()
                                            .setSkuDetails(skuDetails)
                                            .build();

                                    if (ITEM_SKU_diamond_500.equals(sku)) {
                                        premiumUpgradePrice = price;

                                        firstBtn500(params);

                                    }

                                    
                                }
                            } else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ERROR) {
                                Toast.makeText(DiamondsActivity.this, "Error", Toast.LENGTH_SHORT).show();
                            }
                        }

                    });

                } else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.SERVICE_TIMEOUT) {
                    Toast.makeText(DiamondsActivity.this, "Service timeout", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(DiamondsActivity.this, "Failed to connect to the billing client", Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onBillingServiceDisconnected() {
                Toast.makeText(DiamondsActivity.this, "Disconnected from the client", Toast.LENGTH_SHORT).show();
            }
        });

        acknowledgePurchaseResponseListener = new AcknowledgePurchaseResponseListener() {
            @Override
            public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
                Toast.makeText(DiamondsActivity.this, "Purchase acknowledged", Toast.LENGTH_SHORT).show();
            }

        };

4：当用户尝试进行应用内购买或订阅产品订阅时，使用billngClient检查产品是否支持

isFeatureSupported(BillingClient.FeatureType```./* SUBSCRIPTIONS or other */)

方法并调用 billingClient 的 launchBillingFlow 方法

private void firstBtn500(final BillingFlowParams params) {

        firstPurchaseBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                billingClient.launchBillingFlow(DiamondsActivity.this, params);

            }
        });

    }

更新

在这里您可以检查该商品是否已经购买

 @Override
    public void onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases) {

        if (purchases != null && billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {

            for (Purchase purchase : purchases) {
                handlePurchases(purchase);
            }

        } else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
            Toast.makeText(this, "Purchased Canceled", Toast.LENGTH_SHORT).show();
        }

else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED) {
            Toast.makeText(this, "Already Purchased", Toast.LENGTH_SHORT).show();
        }

    }

如果你想购买一次，你需要Acknowledge购买

private void handlePurchases(final Purchase purchase) {

        if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
            //Acknowledge the purchase if it hasn't already been acknowledged.
            if (!purchase.isAcknowledged()) {
                AcknowledgePurchaseParams acknowledgePurchaseParams =
                        AcknowledgePurchaseParams.newBuilder()
                                .setPurchaseToken(purchase.getPurchaseToken())
                                .build();
                billingClient.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);

            }
            

如果您想一次又一次地购买相同的物品（例如应用内/游戏中的硬币或信用或类似的东西）。您需要消费购买 下面是消费购买的代码。

            // Todo: Consume the purchase async
            ConsumeParams consumeParams = ConsumeParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .build();

            ConsumeResponseListener consumeResponseListener = new ConsumeResponseListener() {
                @Override
                public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {

                    Toast.makeText(DiamondsActivity.this, "Purchase successful", Toast.LENGTH_SHORT).show();

                    if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {

                        if (purchase.getSku().equalsIgnoreCase(ITEM_SKU_diamond_500)) {
                            Toast.makeText(DiamondsActivity.this, "Thank you for purchasing!", Toast.LENGTH_SHORT).show();
                        }

                    }

                }
            };

            billingClient.consumeAsync(consumeParams, consumeResponseListener);


        } else if (purchase.getPurchaseState() == Purchase.PurchaseState.PENDING) {

            Toast.makeText(this, "Purchase pending", Toast.LENGTH_SHORT).show();

        }

    }
