与SO和其他网站上的许多答案和评论相反，你不需要使用从谷歌Play下载到测试设备上的产品alpha/beta版本进行初步测试(alpha/beta发布过程通常要花半天时间)。你也不需要从你的开发工作室加载和重新加载一个签名的apk到你的测试设备。

You CAN debug preliminary Google Play in app billing services using the debug app as loaded from your developer studio directly to your test device via ADB. If you are experiencing errors that prevent this, likely you have done something wrong in your code. Pay especially close attention to the CASE of your SKU's (product ids) and their format (for example, if you load your APK as com.mydomain.my_product_id, be sure your try to purchase it this way - providing the same case and domain). Also, pay especially close attention to your itemType - this should be either "inapp" or "subs" for managed/unmanaged in app purchases or subscriptions, respectively.

As suggested by Chirag Patel, provided you have your billing code properly established, perform all testing using the android.test.purchased Sku (product ID) during your preliminary tests. Check for this ID throughout your billing operations to pass it through signature, token and payload checks, since this data is not provided by the Google test system. Additionally, give one of your test products this ID to test its purchase, unlock/load and presentation all the way through your schema. To CLEAR the purchase, simply consume it, passing the same Sku AND a token string formatted this way - no other fields are relevant :

    "inapp:"+appContext.getAppContext().getPackageName()+":android.test.purchased";

Once you have completed this phase of testing, move to semi-live testing with your alpha/beta product. Create a Google group (essentially a mailing list), add your test users emails to it, and add/invite this group to test your device in this phase (performed at the "APK" portion of your app's Google developer listing). Purchases will be simulated but not actually charged - however to clear and re-test the purchases, Google indicates that you must refund them from your Google wallet. THIS is the only phase of testing that requires the time-consuming process of using alpha/beta loads and test users.

这是测试调试/发布版本&如果应用程序是由Play签名(这意味着从谷歌Play交付的应用程序的签名证书与使用Android Studio从您的机器安装应用程序时的证书不同)。

检查以下步骤:

Create your product on Google Play Console and activate it. Add license testers (open the Google Play Console -> Settings -> License Testing). Add all the Google accounts listed on your android device. Upload signed app to the internal testing track (it must be in release mode). Use the testing link to check if the app is available to download (make sure the uploaded app version to the internal track matches the version you're testing in debug mode). It takes some time to see the latest uploaded version there, so I recommend clearing the cache of the Play Store app. Run your app in debug mode from Android Studio. (Again, the app version and build number must match the values on the published version to the internal track).

我在两个不同的谷歌Play Console帐户(两个不同的应用程序)上进行了测试，它是有效的。

如果你使用的apk版本与谷歌比赛中的apk版本不同，就会发生这种情况。

你需要用你的实际证书签署APK。然后将其安装到测试设备上。然后您可以测试InAppBilling。如果您正在通过eclipse直接运行到设备(在调试模式下)来测试应用程序，那么您将得到这个错误。

如果你使用android.test. bought作为SKU，它会一直工作，但是在你的最终响应中不会有developerPayload。

如果你使用的是你自己的应用项目草稿，你可以一直测试，但你会被收费，所以之后你必须自己退款。

您不能使用用于谷歌游戏开发控制台的相同gmail帐户购买物品。

在旧的开发控制台:

设置->帐户详细信息->许可证测试-> Gmail具有测试访问权限的帐户，并在这里键入您的帐户

在新的开发控制台:

输入您的Gmail帐户，点击“Enter”，然后点击“Save”。

我也遇到了同样的问题，在我读到DZDomi的帖子之前，问题没有解决。突然发现在谷歌开发人员控制台中有一个设置需要启用。在“In app purchases”部分，你的产品有一行，最右边是它的状态。它应该是活跃的!
