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。

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.

这里没有提到的另一个原因是，您需要在真正的设备上进行测试。 随着模拟器变得越来越好，这是一个很容易犯的错误。

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。

在我的情况下，由于安装的apk和上传到市场的apk的签名不同，我看到了相同的消息。

我的问题是，我试图用调试检查它。密钥库，我是说在eclipse中运行它。我将它与我在alpha模式下发布的密钥存储库一起导出(在您可以测试它之前必须发布它)。把它安装在我的手机里，然后我就可以正常测试了。
