Android 应用内计费：对应用程序进行采样并将数据存储在数据库中

谁能解释一下为什么Android只在

onRestoreTransactionsResponse

中存储数据，而不在

onRequestPurchaseResponse

中存储数据

既然这样做了，我不知道如何测试我的应用程序-如果我使用（android.test.purchased），那么就永远不会调用

onRestoreTransactionsResponse

。 如果我使用自己的产品id，我会得到一个错误，即不允许购买（我的应用程序上载到Android Market，但未发布；产品id已发布）

---

（我的应用程序只支持一种产品—“付费版应用程序”，可能我应该使用一些不同于示例应用程序的方法？

要知道一件事，要能够测试您自己的项目，您必须创建一个已签名的应用程序apk，并在您的设备上手动安装它（这样对我很有效，否则我就犯了和你一样的错误）

我希望它能有所帮助！

示例应用程序附带的PurchaseObserver文件中提供了解释- onRequestPurchaseResponse：

/**
 * This is called when we receive a response code from Market for a
 * RequestPurchase request that we made.  This is NOT used for any
 * purchase state changes.  All purchase state changes are received in
 * {@link #onPurchaseStateChange(PurchaseState, String, int, long)}.
 * This is used for reporting various errors, or if the user backed out
 * and didn't purchase the item.  The possible response codes are:
 *   RESULT_OK means that the order was sent successfully to the server.
 *       The onPurchaseStateChange() will be invoked later (with a
 *       purchase state of PURCHASED or CANCELED) when the order is
 *       charged or canceled.  This response code can also happen if an
 *       order for a Market-managed item was already sent to the server.
 *   RESULT_USER_CANCELED means that the user didn't buy the item.
 *   RESULT_SERVICE_UNAVAILABLE means that we couldn't connect to the
 *       Android Market server (for example if the data connection is down).
 *   RESULT_BILLING_UNAVAILABLE means that in-app billing is not
 *       supported yet.
 *   RESULT_ITEM_UNAVAILABLE means that the item this app offered for
 *       sale does not exist (or is not published) in the server-side
 *       catalog.
 *   RESULT_ERROR is used for any other errors (such as a server error).

onRestoreTransactionsResponse只是对我们请求的响应（而不是购买状态）：

如果我在RestoreTransactionsResponse上调用，那么也会调用onRequestPurchaseResponse。

谢谢。但是我可以调试这样的应用程序吗？

/**
 * This is called when we receive a response code from Android Market for a
 * RestoreTransactions request that we made.  A response code of
 * RESULT_OK means that the request was successfully sent to the server.
