Google Play帐单库-querySkuDetailsAsync有时会返回BillingResponseCode.ERROR（6）

Question

我使用的是Google Play结算库2.0.3（implementation 'com.android.billingclient:billing:2.0.3'），它在大多数情况下都可以正常运行，但是对于某些用户，原因未知，querySkuDetailsAsync() method occasionally fails with BillingResponseCode.ERROR (6) error code...

有人知道吗？除了“ API操作期间发生致命错误”之外，其他任何地方都未说明此错误的原因。谁能说出为什么会这样吗？

编辑： 我正在使用文档中的方法（https://developer.android.com/google/play/billing/billing_library_overview）：

public interface QuerySkuDetailsListener {
        void onSuccess(List<SkuDetails> skuDetailsList);

        void onErrorProductsHaveDifferentTypes();

        void onBillingClientError(int error_code);
    }

    public void querySkuDetails(final QuerySkuDetailsListener querySkuDetailsListener, final Product... products) {
        if (products.length < 1) {
            //ERROR_NO_PRODUCTS_TO_QUERY
            throw new NullPointerException();
        }

        String querySkuType = products[0].getSkuType();

        SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
        List<String> skuList = new ArrayList<>();
        for (Product product : products) {
            skuList.add(product.getSku());
            if (!product.getSkuType().equals(querySkuType)) {
                //ERROR_SKU_TYPE_CANT_BE_DIFFERENT
                querySkuDetailsListener.onErrorProductsHaveDifferentTypes();
                return;
            }
        }
        params.setSkusList(skuList).setType(querySkuType);

        billingClient.querySkuDetailsAsync(params.build(), new SkuDetailsResponseListener() {
            @Override
            public void onSkuDetailsResponse(BillingResult billingResult, List<SkuDetails> skuDetailsList) {
                if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && skuDetailsList != null) {
                    querySkuDetailsListener.onSuccess(skuDetailsList);
                }
                else {
                    //ERROR QUERYING SKU DETAILS
                    querySkuDetailsListener.onBillingClientError(billingResult.getResponseCode());
                }
            }
        });
    }

然后我像这样使用它：

        private void initiatePurchaseFlow(final Activity activity, @Nullable final Product oldProduct, final Product product, final JsonObject metadata, final InitiatePurchaseListener initiatePurchaseListener) {

                //Check if billingClient is ready
                if (billingClient.isReady()) {
                    querySkuDetails(new QuerySkuDetailsListener() {
                            @Override
                            public void onSuccess(List<SkuDetails> skuDetailsList) {
                                // Process the result.
                                BillingFlowParams.Builder flowParamsBuilder = BillingFlowParams.newBuilder();
                                flowParamsBuilder.setSkuDetails(skuDetailsList.get(0));
                                if (null != oldProduct) {
                                    flowParamsBuilder.setOldSku(oldProduct.getSku());
                                    flowParamsBuilder.setReplaceSkusProrationMode(BillingFlowParams.ProrationMode.IMMEDIATE_WITH_TIME_PRORATION);
                                }
                                BillingFlowParams flowParams = flowParamsBuilder.build();
                                int responseCode = billingClient.launchBillingFlow(activity, flowParams).getResponseCode();
                                if (responseCode == BillingClient.BillingResponseCode.OK) {
                                    //SUCCESS, OK
                                    ...Rest of the irrelevant code...
                                }
                                else {
                                    //ERROR_IN_LAUNCHING_BILLING_FLOW
                                    dispenseInitiatePurchaseFlowError(activity, initiatePurchaseListener, InitiatePurchaseErrorCodes.ERROR_IN_LAUNCHING_BILLING_FLOW, getBillingClientErrorDescription(responseCode));
                                }
                            }

                            @Override
                            public void onErrorProductsHaveDifferentTypes() {
                                //ERROR_IN_QUERYING_SKU_DETAILS_PRODUCTS_HAVE_DIFFERENT_TYPES
                                dispenseInitiatePurchaseFlowError(activity, initiatePurchaseListener, InitiatePurchaseErrorCodes.ERROR_IN_QUERYING_SKU_DETAILS_PRODUCTS_HAVE_DIFFERENT_TYPES, getBillingClientErrorDescription(0));
                            }

                            @Override
                            public void onBillingClientError(int error_code) {
                                //ERROR_IN_QUERYING_SKU_DETAILS
                                dispenseInitiatePurchaseFlowError(activity, initiatePurchaseListener, InitiatePurchaseErrorCodes.ERROR_IN_QUERYING_SKU_DETAILS, getBillingClientErrorDescription(error_code));
                            }
                        }, product);
                }
                else {
                    //ERROR_BILLING_CLIENT_IS_NOT_READY
                    //Trying to reconnect once          
                    billingClient.startConnection(new BillingClientStateListener() {
                        @Override
                        public void onBillingSetupFinished(BillingResult billingResult) {
                            if (billingResult.getResponseCode() == BillingResponse.OK) {
                                //launching again
                                initiatePurchaseFlow(activity, oldProduct, product, metadata, initiatePurchaseListener);
                            }
                            else {
                            // showing an error dialog
                            dispenseInitiatePurchaseFlowError(activity, initiatePurchaseListener, InitiatePurchaseErrorCodes.ERROR_BILLING_CLIENT_IS_NOT_READY, getBillingClientErrorDescription(billingResult.getResponseCode()));
                            }
                        }
                        @Override
                        public void onBillingServiceDisconnected() {

编辑： 用户可以简单地作弊吗？例如，使用破解的Google Play商店/其他与购买混乱的软件？因为无论我做什么，在我拥有的任何设备上都没有收到此错误。

编辑： 到目前为止，我发现如果您使用幸运的修补程序破解应用程序，onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases)则开票客户端的方法将返回此错误代码（BillingResponseCode.ERROR），但是我没有得到任何错误querySkuDetailsAsync()。。。这可能相关吗？

编辑： 另外，我已经在google issuetracker中创建了一个问题，如果您愿意的话，也可以在那里支持我。https://issuetracker.google.com/issues/139631105

Answer 1

为了供将来参考和其他一些遭受此问题的人（例如 IAB 3.0.1 的我），OP 打开的问题跟踪器错误中的某人发布了一条评论，说明如果我们收到此代码，我们应该如何反应

错误 6 ( https://developer.android.com/reference/com/android/billingclient/api/BillingClient.BillingResponseCode#error ) 通常表示来自我们的后端服务器的暂时性错误。此错误代码应触发重试，在大多数情况下应该会成功。

示例代码：

@Override
public void onSkuDetailsResponse(@NonNull BillingResult billingResult, @Nullable List<SkuDetails> list) {
    Utils.log("BILLING: onSkuDetailsResponse(). Result (" + billingResult.getResponseCode() + ") List size: " + (list == null ? "null" : list.size()));
    if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && list != null) {
        if (mSkuQueryErrorCounter > 0) mSkuQueryErrorCounter--;
        // process the SkuDetail list...
        }
    } else {
        // https://issuetracker.google.com/issues/139631105#comment11
        mSkuQueryErrorCounter++;
        if (mSkuQueryErrorCounter <= 2) scheduleUpdate(NOW);
        else if (mSkuQueryErrorCounter < 5) scheduleUpdate(TEN_SECONDS);
        else if (mSkuQueryErrorCounter < 10) scheduleUpdate(ONE_HOUR);
        else scheduleUpdate(ONE_DAY);
    }
}
