Библиотека биллинга Google Play - consumerAsyn c не работает должным образом - PullRequest

/ 13 июля 2020

Я пытаюсь интегрировать Библиотеку выставления счетов Google Play в наше приложение, чтобы продавать расходные материалы внутри приложения. Согласно официальному руководству по интеграции от разработчика android .com, использование метода consumerAsyn c при покупке позволит пользователю купить продукт снова. Однако для меня этот метод не всегда работает правильно, и пользователь не может купить продукт снова.

Кроме того, в случае сценария «медленная тестовая карта, платеж отклонен», платеж никогда не завершается а метод consumerAsyn c вообще не работает.

Я рассмотрел все похожие вопросы о переполнении стека, но решение не работает. Кроме того, официальный пример приложения от Google в основном ориентирован на модель подписки, поэтому это тоже не помогает.

Вы можете взглянуть на мою реализацию ниже:

public class PremiumMembershipActivity extends AppCompatActivity implements AcknowledgePurchaseResponseListener {

// Billing Client
private BillingClient billingClient;
private List<String> skuList = new ArrayList<String>();

private String sku = "buy_1000_credits";

private PurchasesUpdatedListener purchaseUpdateListener = new PurchasesUpdatedListener() {
    @Override
    public void onPurchasesUpdated(@NonNull BillingResult billingResult, @Nullable List<Purchase> list) {

        methodForPurchaseUpdated(billingResult, list);
    }
};

private ConsumeResponseListener consumeResponseListener = new ConsumeResponseListener() {
    @Override
    public void onConsumeResponse(BillingResult billingResult, @NotNull String s) {
        if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK){
        }
    }
};


private AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = new AcknowledgePurchaseResponseListener() {
    @Override
    public void onAcknowledgePurchaseResponse(@NotNull BillingResult billingResult) {
    }
};

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_premium);

    mBuyCredits = findViewById(R.id.premium_membership_buy_credits_card);
    skuList.add(sku);
    setupBillingClient();
}

    billingClient.startConnection(new BillingClientStateListener() {
        @Override

            }else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ERROR) {
