账单流程参数生成器——为测试静态的Google Play计费响应设置Sku详情。

Question

我正在使用三个预留的产品ID来测试静态Google Play计费的购买功能：responses：

• android.test.purchased
• android.test.canceled
• android.test.item_unavailable

但是，在BillingFlowParams.Builder类中，setSku和setType似乎已过时。相反，我们应该使用setSkuDetails(SkuDetails).

在示例代码中，我应该如何更改BillingFlowParams来使用SkuDetails进行测试产品ID？

BillingFlowParams flowParams = BillingFlowParams.newBuilder()
     .setSku(skuId)
     .setType(SkuType.INAPP) 
     .build();
int responseCode = mBillingClient.launchBillingFlow(flowParams);

问题和答案都已过时。BillingFlowParams不再直接使用，现在返回响应的是BillingResult而不是responseCode。因此，最新的答案与之前的答案非常接近。 - Abhinav Saxena

Answer 1

你应该使用BillingClient.querySkuDetailsAsync获取SkuDetails，示例代码可能如下所示：

private BillingClient mBillingClient;

// ....

mBillingClient = BillingClient.newBuilder(this).setListener(new PurchasesUpdatedListener() {
    @Override
    public void onPurchasesUpdated(int responseCode, @Nullable List<Purchase> purchases) {
        if (responseCode == BillingClient.BillingResponse.OK
                && purchases != null) {

            // do something you want

        } else if (responseCode == BillingClient.BillingResponse.USER_CANCELED) {
        } else {
        }
    }
}).build();


mBillingClient.startConnection(new BillingClientStateListener() {
    @Override
    public void onBillingSetupFinished(@BillingClient.BillingResponse int billingResponseCode) {        

if (billingResponseCode == BillingClient.BillingResponse.OK) {
        // The billing client is ready. You can query purchases here.

List<String> skuList = new ArrayList<>();
        skuList.add("android.test.purchased");

SkuDetailsParams skuDetailsParams = SkuDetailsParams.newBuilder()
                    .setSkusList(skuList).setType(BillingClient.SkuType.INAPP).build();
mBillingClient.querySkuDetailsAsync(skuDetailsParams,
                    new SkuDetailsResponseListener() {
 @Override
  public void onSkuDetailsResponse(int responseCode, List<SkuDetails> skuDetailsList) {

  BillingFlowParams flowParams = BillingFlowParams.newBuilder()
                                    .setSkuDetails(skuDetailsList.get(0))
                                    .build();
  int billingResponseCode = billingClient.launchBillingFlow(SkuActivity.this, flowParams);
  if (billingResponseCode == BillingClient.BillingResponse.OK) {
                                // do something you want
                            }
                        }
                    });
                 }
               }


@Override
    public void onBillingServiceDisconnected() {
        // Try to restart the connection on the next request to
        // Google Play by calling the startConnection() method.
    }
});

@Ping，注意啦，谷歌已经更新了它的示例代码。上面的代码可能无法正确运行，所以你应该参考最新版本。 - Renkuei

@Renkuei 的回答很简洁明了，但是你提供的链接（至少在我发表这条评论时）也使用了已弃用的 setSku 而不是 setSkuDetails，这恰恰是整个问题的重点所在。 - Gichamba

谷歌提到的示例（Renkuei的链接）仍然不是最新的。当他们更改库时，谷歌能否检查所有示例？ - chksr

在构建 billingClient 实例时，不要忘记添加 .enablePendingPurchases()。 - Kirill Karmazin

@KirillKarmazin，为了支持.enablePendingPurchases()，是否需要实现任何特殊的内容？我没有看到任何东西，所以只是在确认一下... - Someone Somewhere

Answer 2

我会尽力帮助您翻译。这段文本的含义是：“我正在发布一个关于应用内计费的逐步过程，我最近在Billing Library 4.0版本发布后进行了测试。”

“Google帮助资源可以在这里找到。”

“首先要做的事情是：更新你的build.gradle文件。”

dependencies {
    def billing_version = "4.0.0"

    implementation "com.android.billingclient:billing:$billing_version"
}

现在，进入编程部分：BillingActivity.java。

private BillingClient mBillingClient;

// ...


submitButton.setOnClickListener(v -> {
    mBillingClient = BillingClient.newBuilder(this).enablePendingPurchases().setListener(new PurchasesUpdatedListener() {
        @Override
        public void onPurchasesUpdated(BillingResult billingResult, List<Purchase> purchases) {
            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK
                    && purchases != null) {
                for (Purchase purchase : purchases) {
                    handlePurchase(purchase);
                }
                // Perform your Successful Purchase Task here 
                
                Snackbar.make(findViewById(android.R.id.content), "Great!! Purchase Flow Successful! :)", Snackbar.LENGTH_LONG).show();
                dismiss();
            } else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
                // Handle an error caused by a user cancelling the purchase flow.
                Snackbar.make(findViewById(android.R.id.content), "User Cancelled the Purchase Flow!", Snackbar.LENGTH_LONG).show();
            } else {
                // Handle any other error codes.
                Snackbar.make(findViewById(android.R.id.content), "Error! Purchase Task was not performed!", Snackbar.LENGTH_LONG).show();
            }
        }
    }).build();

    mBillingClient.startConnection(new BillingClientStateListener() {

        @Override
        public void onBillingSetupFinished(@NonNull BillingResult billingResult) {

            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                // The BillingClient is ready. You can query purchases here.

                List<String> skuList = new ArrayList<>();
                skuList.add("billing_template_1");
                skuList.add("billing_template_2");
                SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
                params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP);
                mBillingClient.querySkuDetailsAsync(params.build(),
                        new SkuDetailsResponseListener() {
                            @Override
                            public void onSkuDetailsResponse(BillingResult billingResult,
                                                             List<SkuDetails> skuDetailsList) {
                                // Process the result.
                                // Retrieve a value for "skuDetails" by calling querySkuDetailsAsync().
                                BillingFlowParams billingFlowParams = BillingFlowParams.newBuilder()
                                        .setSkuDetails(skuDetailsList.get(0))
                                        .build();
                                int responseCode = mBillingClient.launchBillingFlow(activity, billingFlowParams).getResponseCode();
                            }
                        });
            }
        }

        @Override
        public void onBillingServiceDisconnected() {
            // Try to restart the connection on the next request to Google Play by calling the startConnection() method.
            Toast.makeText(BillingActivity.this, "Service Disconnected!", Toast.LENGTH_SHORT).show();
        }
    });
});
        
void handlePurchase(Purchase purchase) {
    ConsumeParams consumeParams =
            ConsumeParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .build();

    ConsumeResponseListener listener = new ConsumeResponseListener() {
        @Override
        public void onConsumeResponse(BillingResult billingResult, @NonNull String purchaseToken) {
            if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
                // Handle the success of the consume operation.
            }
        }
    };
    mBillingClient.consumeAsync(consumeParams, listener);
}
    
    
private void dismiss() {
        Intent intent = new Intent();
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        finish();
    }

注意：

• 这只是对@Renkuei答案的更新版本。
• 不要忘记.enablePendingPurchase()
• 不要忘记从您的开发者控制台执行skuList.add("billing_template_1")。 因此，billing_template_1是您的Monetise > Products > In-app products > Prouduct ID的名称
