Google Play Billing Library - querySkuDetailsAsync 偶尔 returns BillingResponseCode.ERROR (6)

Question

我正在使用 Google Play Billing Library 2.0.3 (implementation 'com.android.billingclient:billing:2.0.3')，它在大多数情况下工作正常，但对于某些用户来说原因未知，querySkuDetailsAsync() method occasionally fails with BillingResponseCode.ERROR (6) error code...

有人知道吗？这个错误的原因没有在任何地方解释，除了它是一个 "Fatal error during the API action"。谁能说出为什么会这样？

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());
                }
            }
        });
    }

那我就这样用:

        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 {

                            }
                        }
                        @Override

编辑： 用户可以简单地作弊吗？例如使用破解的 google play store/other 软件干扰购买？因为无论我做什么，我都没有在我拥有的任何设备上收到此错误。

编辑： 到目前为止，如果您使用幸运补丁破解应用程序，我发现计费客户端的 onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases) 方法 returns 这个错误代码 (BillingResponseCode.ERROR)，但我没有收到任何错误querySkuDetailsAsync()...这可能是相关的吗？

为了将来的参考和其他一些遭受此痛苦的人（比如我在 IAB 3.0.1），OP 打开的问题跟踪器错误中的某个人发表了关于如果我们收到此代码我们应该如何反应的评论

Error 6 (https://developer.android.com/reference/com/android/billingclient/api/BillingClient.BillingResponseCode#error) usually represents a transient error from our backend servers. This error code should trigger a retry which in most cases should succeed.

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);
    }
}
