請求書消耗品で

Question

私は消耗品（コイン）を販売するためのGoogleアプリ内課金を実装しようとしています。私は非消耗品でそれをテストし、うまくいきました。しかし、私はそれを消耗させることはできません。私がそれをテストするたびに、私は一度しか買うことができません！ ここに私のコードです：

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.

私の英語と感謝のために申し訳ありません。

Answer 1

私が最初に気づいたのは、checkOwnedItemsメソッドの直後にmakePurchaseを呼び出したことです。>例外例外：別の非同期操作（在庫の更新）が進行中であるため、非同期操作（launchPurchaseFlow）を開始できません。その後、私はボタンを使ってmakePurchaseを呼び出しましたが、それはまだ動作していませんでした...すべてのリスナーで成功または失敗+例外をトーストしたので、onIabPurchaseFinishedメソッドが呼び出されていないことを知っていました。 https://stackoverflow.com/a/14968203/4106137。

Answer 2

私はまた、ネイティブアプリ内課金システムを使用してトラブルを抱えていたが、その後、私はthis library

はそれが役に立てば幸いました。
