从服务器[DF-AA-20]检索信息时，应用内购买错误

问题描述

我正在尝试启用应用内结算功能.我已经在Google Play控制台上创建了应用内商品，并获得了我的许可证密钥.当我尝试购买产品时.我收到此图片错误.

i'm trying to enable in app billing. I've created In-app-products on my google play console and got my License key. When i try to purchase product. I get this image error.

这是我用来创建BillingProcessor的代码.

Here is the code i use to create BillingProcessor.

bp = new BillingProcessor(this, LICENSE_KEY, MERCHANT_ID, new BillingProcessor.IBillingHandler() {
        @Override
        public void onProductPurchased(@NonNull String productId, @Nullable TransactionDetails details) {
            showToast("onProductPurchased: " + productId);
            updateTextViews();
        }
        @Override
        public void onBillingError(int errorCode, @Nullable Throwable error) {
            showToast("onBillingError: " + Integer.toString(errorCode));
        }
        @Override
        public void onBillingInitialized() {
            showToast("onBillingInitialized");
            readyToPurchase = true;
            updateTextViews();
        }
        @Override
        public void onPurchaseHistoryRestored() {
            showToast("onPurchaseHistoryRestored");
            for(String sku : bp.listOwnedProducts())
                Log.d(LOG_TAG, "Owned Managed Product: " + sku);
            for(String sku : bp.listOwnedSubscriptions())
                Log.d(LOG_TAG, "Owned Subscription: " + sku);
            updateTextViews();
        }
    });

LICENSE_KEY是我从Google Play控制台获得的许可证密钥，而MERCHANT_ID为空.

LICENSE_KEY is my license key from google play console, and MERCHANT_ID is null.

这是我购买物品的方式.

This is how i buy items.

bp.purchase(this,PRODUCT_ID);

我在Google Play控制台中使用的PRODUCT_ID是product1的地方，这是我的应用内商品的示例.

Where PRODUCT_ID is product1 which i use in my google play console, here is the example of my in-app products.

任何想法如何解决此问题? DF-AA-20问题只有一个stackoverflow问题，没有答案.互联网上也没有关于它的信息.我尝试使用模拟器和Android手机.

Any idea how to fix this ? There is only one stackoverflow question with DF-AA-20 problem which has no answers. And there is no information on the internet about it. I have tried to use emulator and my android phone.

推荐答案

DF-AA-20 意味着您的应用程序没有以任何方式在Play商店中发布.通常是因为以下任一原因:

DF-AA-20 means your app is not published in any way on the Play store. This is normally because either:

• 您尚未发布.要测试应用内结算，必须将其至少推送到alpha.请参见测试IAB文档了解更多信息
• 您的应用或开发者帐户已被禁止/暂停滥用
• 您对软件包名称/applicationId进行了一些更改，因此在您的apk中它与Play上的不匹配.开发人员有时会通过构建风味来做到这一点

• you haven't published it yet. To test In-App Billing it must be pushed to at least alpha. See the testing IAB docsfor more information
• your app or developer account has been banned/suspended for abuse
• you make some change to your package name/applicationId, so that in your apk it doesn't match the one on Play. Developers sometimes do this with build flavors
