Android Google 计费客户端 - onSkuDetailsResponse 列表始终为空

Android Google Billing Client - onSkuDetailsResponse Always Empty List

我想知道你能帮忙吗。我按照 https://developer.android.com/google/play/billing/integrate 上的说明进行操作,但我似乎无法让购买流程正常运行。账单似乎设置正常,但当我尝试查询我的应用内商品时,列表总是 return 为空。有人可以帮忙吗?

在我的应用级别 build.gradle 文件中,我包含了 Google 计费 SDK:

implementation 'com.android.billingclient:billing:3.0.0'

然后我创建了一个 activity 来测试代码。它首先初始化 BillingClient 并启动连接。连接似乎正确地完成了设置。设置正确后,我会尝试在 'Store presence' > 'In-app products' > 'Manage products'

下的 Google Play Console 中查询可用的产品

下面是 Activity 中应该启动进程和 return SkuDetails 列表的代码,但不幸的是 return 返回时是空的。

private BillingClient billingClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_billing);

    this.billingClient = BillingClient.newBuilder(this)
            .enablePendingPurchases()
            .setListener(this.purchaseUpdateListener)
            .build();
    this.billingClient.startConnection(billingClientStateListener);
}

private PurchasesUpdatedListener purchaseUpdateListener = new PurchasesUpdatedListener() {
    @Override
    public void onPurchasesUpdated(@NonNull BillingResult billingResult, @Nullable List<Purchase> list) {
        Log.d("Billing", "onPurchasesUpdated - List Size: " + list.size());
    }
};

private BillingClientStateListener billingClientStateListener = new BillingClientStateListener() {
    @Override
    public void onBillingSetupFinished(@NonNull BillingResult billingResult) {
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
            Log.d("Billing", "onBillingSetupFinished - OK");
            queryProducts();
        } else {
            Log.d("Billing", "onBillingSetupFinished - Something wrong response Code: " + billingResult.getResponseCode());
        }
    }

    @Override
    public void onBillingServiceDisconnected() {
        Log.d("Billing", "Service disconnected");
    }
};

private void queryProducts() {
    List<String> productIdsList = new ArrayList<>();
    productIdsList.add("test.billing.001");

    SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
    params.setSkusList(productIdsList).setType(BillingClient.SkuType.INAPP);
    this.billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {
        @Override
        public void onSkuDetailsResponse(@NonNull BillingResult billingResult, @Nullable List< SkuDetails > list) {
            Log.d("Billing", "onSkuDetailsResponse - List Size: " + list.size());
        }
    });
}

因此对于遇到类似问题的任何人来说,似乎(无论如何对我而言)我的应用程序需要成功发布才能从应用程序中检索应用程序内产品。我的应用发布后,我就可以查询和使用应用内商品了。
