在應用程序結算消耗品

Question

我試圖實施谷歌應用程序內結算銷售消耗品（硬幣）。我用非消耗品進行測試，效果很好。但我不能讓它消耗。每次我測試它，我只能買一次！ 這裏是我的代碼：

public class MainActivity extends AppCompatActivity { IabHelper mHelper;

boolean verifyDeveloperPayload(Purchase p) { 
    String payload = p.getDeveloperPayload(); 

/* 
* TODO: verify that the developer payload of the purchase is correct. It will be 
* the same one that you sent when initiating the purchase. 
* 
* WARNING: Locally generating a random string when starting a purchase and 
* verifying it here might seem like a good approach, but this will fail in the 
* case where the user purchases an item on one device and then uses your app on 
* a different device, because on the other device you will not have access to the 
* random string you originally generated. 
* 
* So a good developer payload has these characteristics: 
* 
* 1. If two different users purchase an item, the payload is different between them, 
* so that one user's purchase can't be replayed to another user. 
* 
* 2. The payload must be such that you can verify it even when the app wasn't the 
* one who initiated the purchase flow (so that items purchased by the user on 
* one device work on other devices owned by the user). 
* 
* Using your own server to store and verify developer payloads across app 
* installations is recommended.

對不起，我的英語和感謝。

Answer 1

我明白了：因此，我的第一個問題是我在checkOwnedItems方法之後調用了makePurchase - >拋出異常：由於另一個異步操作（刷新清單）正在進行，無法啓動異步操作（launchPurchaseFlow）。然後我使用一個按鈕來調用makePurchase，它仍然沒有工作......因爲我已經成功敬酒或失敗+在所有聽衆中的異常我知道onIabPurchaseFinished方法沒有被調用，所以我Google搜索並找到了這個答案： https://stackoverflow.com/a/14968203/4106137。

Answer 2

我也有使用本地應用內結算系統故障，但後來我發現this library

希望它幫助。
