如何在 inapp v3 android 中获取订阅到期日期

Question

您好，我已经使用 android-inapp-billing-v3 实施了一年订阅项目的 inapp billing V3。我想在我的应用程序中显示剩余天数。我正在致电 getSubscriptionTransactionDetails 以获取产品的交易详细信息，但它总是 returns null。这是我的代码。

  private BillingProcessor startInappCheck(){

         bp = new BillingProcessor(mContext, BASE64ENCODEDPUBLICKEY, new BillingProcessor.IBillingHandler() {
                @Override
                public void onProductPurchased(String productId, TransactionDetails details) {
                    LogUtils.e(TAG, "onProductPurchased :" +productId);
    //              showToast("onProductPurchased: " + productId);

                }
                @Override
                public void onBillingError(int errorCode, Throwable error) {

                    LogUtils.e(TAG, "onBillingError :" +errorCode);


                }
                @Override
                public void onBillingInitialized() {
  //                showToast("onBillingInitialized");
                    readyToPurchase = true;



                    try{
                        SkuDetails subs = bp.getSubscriptionListingDetails(SUBSCRIPTION_ID);


                        LogUtils.d(TAG, "Owned Subscription: " + subs.toString());
                       TransactionDetails tr = bp.getSubscriptionTransactionDetails(SUBSCRIPTION_ID);
                      LogUtils.d(TAG, "Owned Subscription: " + tr.toString());

                    }catch (Exception e) {
                        // TODO: handle exception
                    }


                }
                @Override
                public void onPurchaseHistoryRestored() {
   //                   showToast("onPurchaseHistoryRestored");
                    for(String sku : bp.listOwnedSubscriptions()){
                        LogUtils.d(TAG, "Owned Subscription: " + sku);
                    }
   //                showToast("onPurchaseHistoryRestored");

                }
            });
         return bp;
    }

我从 onCreate 调用了这个方法。

  @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
     if (!bp.handleActivityResult(requestCode, resultCode, data))
            super.onActivityResult(requestCode, resultCode, data);

}

我的订阅项目按钮在 fragment 中实现。还有一个问题我发现在成功订阅后 onProductPurchased 没有被调用但是我已经实现了 onResume 中的逻辑来更新 UI if bp.isSubscribed(SUBSCRIPTION_ID) returns true。请告诉我如何获取订阅开始日期和到期日期。

Answer 1

我想给出我自己问题的答案，这样如果有人在寻找相同的答案，就可以找到解决方案。经过大量 google 我没有找到我正在寻找的确切解决方案所以我在 BillingProcessor class 在 iabv3 library 项目中创建了一个方法，其中 returns Bundle 带有购买详细信息，我在其中获取购买日期。现在我可以找到到期日了。该方法如下所示

public Bundle getPurchases(){
    if (!isInitialized())
        return null;
    try{
        return  billingService.getPurchases(Constants.GOOGLE_API_VERSION, contextPackageName, Constants.PRODUCT_TYPE_SUBSCRIPTION, null);
    }catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

Answer 2

我已使用此代码在计费处理器库中获取购买详细信息。

   TransactionDetails transactionDetails = bp.getSubscriptionTransactionDetails(channelModel.getAndroidProductId());
        Log.d(TAG, "initializePaymentSetup: " + transactionDetails.toString());
        Log.d(TAG, "initializePaymentSetup: " + transactionDetails.purchaseInfo.toString());

 transactionDetails.purchaseInfo.purchaseData// this will return the purchase date

Answer 3

我正在使用这个：

@Nullable
public Date getSubscriptionRenewingDate(String sku) {

    // Get the Purchase object:
    Purchase purchase = null;
    Purchase.PurchasesResult purchasesResult = _billingClient.queryPurchases(BillingClient.SkuType.SUBS);
    if (purchasesResult.getPurchasesList() != null) {
        for (Purchase p : purchasesResult.getPurchasesList()) {
            if (p.getSku().equals(sku) && p.getPurchaseState() == Purchase.PurchaseState.PURCHASED && p.isAutoRenewing()) {
                purchase = p;
                break;
            }
        }
    }

    // Get the SkuDetails object:
    SkuDetails skuDetails = null;
    for (SkuDetails s : _skuDetails) { // _skuDetails is an array of SkuDetails retrieved with querySkuDetailsAsync
        if (s.getSku().equals(sku)) {
            skuDetails = s;
            break;
        }
    }

    if (purchase != null && skuDetails != null) {

        Date purchaseDate = new Date(purchase.getPurchaseTime());
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(purchaseDate);

        Date now = new Date();

        while (calendar.getTime().before(now)) {

            switch (skuDetails.getSubscriptionPeriod()) {

                case "P1W": calendar.add(Calendar.HOUR, 7*24); break;
                case "P1M": calendar.add(Calendar.MONTH, 1); break;
                case "P3M": calendar.add(Calendar.MONTH, 3); break;
                case "P6M": calendar.add(Calendar.MONTH, 6); break;
                case "P1Y": calendar.add(Calendar.YEAR, 1); break;
            }
        }

        return calendar.getTime();
    }

    return null;
}
