解决方案

在play store上传应用后请稍等，因为谷歌需要一段时间来更新应用版本。它会起作用的!

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。

如果你发布的版本与你在手机上测试的版本不一样，也会发生同样的情况。

例如，上传的版本是android:versionCode="1"，而你在你的手机上测试的版本是android:versionCode="2"

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。

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.

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”。
