android - Google应用内结算:restoreTransactions()行为

我正在为某个应用程序进行Google应用内购买。我创建了一个ID为“ app.test.item”的被管理产品项目。我遵循了Google文档中指定的所有其他步骤。首次购买的应用程序运行正常。但是，当我尝试取消安装应用程序并再次安装时。该应用程序运行还原交易请求。在我根据从市场返回的RESULT_OK使购买状态为true的情况下调用onRestoreTransactionsResponse（）方法。我的疑问是，应用程序如何知道仅购买了名为“ app.test.item”的项目并因此将其还原。我也有其他一些项目，例如“ app.test.second.item”。应用内结算如何看清两者之间的区别。我已经使用了Google提供的应用内结算代码。刚刚提到了一些用于存储购买状态的共享首选项。我在这里做错什么吗？请指导我。

我也想在调试模式下测试此应用程序，以便可以跟踪工作流程。但是，应使用发布版本对应用程序进行签名。有什么办法可以在调试版本中完全运行此应用程序（以测试还原事务）。我了解了使用保留的productId作为“ android.test.purchased”进行常规购买的常规工作流程。但是我需要测试restoreTransactions（）。任何帮助表示赞赏。

我将在此处发布PurchaseObserver示例代码。

谢谢，

private class DungeonsPurchaseObserver extends PurchaseObserver {
    public DungeonsPurchaseObserver(Handler handler) {
        super(Dungeons.this, handler);
    }

            restoreDatabase();

最佳答案

调试被管理产品可能很困难，因为除非使用发布密钥对应用进行签名，否则您将无法使用它们。因此，在测试IAB时，我用发布密钥对调试版本进行签名。

对于多种产品，您需要检查商品编号。每个产品都会调用onPurchaseStateChange。

例如

public void onPurchaseStateChange(PurchaseState purchaseState, String itemId, int quantity, long purchaseTime, String developerPayload) {

    if (itemId.equals("app.test.item") {
        switch (purchaseState) {

        case PURCHASED:
            Log.i("Billing","Purchased app.test.item");
            break;

        default:
            Log.i("Billing","Something else");
            break;

        }
    }
