应用内计费：SampleApplication 并将数据存储在数据库中

Question

有人可以解释一下为什么 Android 的 示例应用程序 存储数据仅在 onRestoreTransactionsResponse 中而不在 onRequestPurchaseResponse 中存在于数据库中？

既然已经完成了，所以我不确定如何测试我的应用程序 - 如果我使用 standard产品 ID (android.test.purchased)，则永远不会调用 onRestoreTransactionsResponse。 如果我使用自己的产品 ID - 我收到不允许购买的错误（我的应用程序已上传到 Android Market，但未发布；产品 ID 已发布）。

（我的应用程序仅支持一种产品 - “应用程序的付费版本”，也许我应该使用一些与示例应用程序不同的方法？）

Answer 1

说明可在示例应用程序随附的 PurchaseObserver 文件中找到 -
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 只是对我们的请求的响应（而不是购买状态）：

/**
 * 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.
 */

如果我调用 onRestoreTransactionsResponse，则 onRequestPurchaseResponse > 也称为。

要知道的一件事是，为了能够测试您自己的项目，您必须创建您的应用程序的签名 apk 并将其手动安装在您的设备上（它对我来说就是这样，否则我会遇到与您相同的错误）

我希望有帮助！
