Android 应用内购买同一类型产品的多种类型订阅

Question

在这里，我正在为多种类型的订阅实现 Google 的应用内购买，即 monthly 、 quarterly 、 half-yearly 和 每年一次。我为每个非托管或非托管订阅类型创建了 SkewId。这些订阅包适用于相同类型的工作。但是现在我想知道我怎么知道付款后订阅的订阅天数？

我将托管类型的代码实现为:

 mHelper = new IabHelper(this, base64EncodedPublicKey);
    // enable debug logging (for a production application, you should set
// this to false).
    mHelper.enableDebugLogging(true);
    mHelper.startSetup(new
                               IabHelper.OnIabSetupFinishedListener() {
                                   public void onIabSetupFinished(IabResult result) {
                                       if (!result.isSuccess()) {
                                           Log.d("TAG", "In-app Billing setup failed: " +
                                                   result);
                                       } else {
                                           Log.d("TAG", "In-app Billing is set up OK");
                                       }
                                   }
                               });
}
 IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
        = new IabHelper.OnIabPurchaseFinishedListener() {
    public void onIabPurchaseFinished(IabResult result,
                                      Purchase purchase) {
        if (result.isFailure()) {
            // Handle error
            Log.d("TAG", "We have gas. Consuming it.");
            remove_ads_btn_monthly.setEnabled(true);
            remove_ads_btn_quarterly.setEnabled(true);
            remove_ads_btn_halfyearly.setEnabled(true);
            remove_ads_btn_yearly.setEnabled(true);
            if (plan_duration != 1)
                toast = new CustomToast(RemoveAdsActivity.this, "You've already subscribed package of " + plan_duration + " months.");
            else
                toast = new CustomToast(RemoveAdsActivity.this, "You've already subscribed package of " + plan_duration + " month.");

            return;
        } else if (purchase.getSku().equals(SKU_MONTHLY)) {
            consumeItem();
            remove_ads_btn_monthly.setEnabled(false);
            remove_ads_btn_quarterly.setEnabled(false);
            remove_ads_btn_halfyearly.setEnabled(false);
            remove_ads_btn_yearly.setEnabled(false);
        } else if (purchase.getSku().equals(SKU_HALF_YEARLY)) {
            consumeItem();
            remove_ads_btn_monthly.setEnabled(false);
            remove_ads_btn_quarterly.setEnabled(false);
            remove_ads_btn_halfyearly.setEnabled(false);
            remove_ads_btn_yearly.setEnabled(false);
        } else if (purchase.getSku().equals(SKU_QUARTERLY)) {
            consumeItem();
            remove_ads_btn_monthly.setEnabled(false);
            remove_ads_btn_quarterly.setEnabled(false);
            remove_ads_btn_halfyearly.setEnabled(false);
            remove_ads_btn_yearly.setEnabled(false);
        } else if (purchase.getSku().equals(SKU_ANNUALY)) {
            consumeItem();
            remove_ads_btn_monthly.setEnabled(false);
            remove_ads_btn_quarterly.setEnabled(false);
            remove_ads_btn_halfyearly.setEnabled(false);
            remove_ads_btn_yearly.setEnabled(false);
        }

    }
};

public void consumeItem() {
    mHelper.queryInventoryAsync(mReceivedInventoryListener);
}

IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener
        = new IabHelper.QueryInventoryFinishedListener() {
    public void onQueryInventoryFinished(IabResult result,
                                         Inventory inventory) {

        Purchase gasMonthly = inventory.getPurchase(SKU_MONTHLY);
        Purchase gasYearly = inventory.getPurchase(SKU_ANNUALY);
        Purchase gasQuarterly = inventory.getPurchase(SKU_QUARTERLY);
        Purchase gasHalfYearly = inventory.getPurchase(SKU_HALF_YEARLY);
        if (gasMonthly != null) {
            mHelper.consumeAsync(inventory.getPurchase(SKU_MONTHLY), mConsumeFinishedListener);
            mSubscribedTo = true;
        } else if (gasYearly != null) {
            mHelper.consumeAsync(inventory.getPurchase(SKU_ANNUALY), mConsumeFinishedListener);
            mSubscribedTo = true;
        } else if (gasQuarterly != null) {
            mHelper.consumeAsync(inventory.getPurchase(SKU_QUARTERLY), mConsumeFinishedListener);
            mSubscribedTo = true;
        } else if (gasHalfYearly != null) {
            mHelper.consumeAsync(inventory.getPurchase(SKU_HALF_YEARLY), mConsumeFinishedListener);
            mSubscribedTo = true;
        } else {
            mSubscribedTo = false;
        }
    }
};
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
        new IabHelper.OnConsumeFinishedListener() {
            public void onConsumeFinished(Purchase purchase,
                                          IabResult result) {

                if (result.isSuccess()) {
                    //API
                    remove_ads_btn_monthly.setEnabled(true);
                    remove_ads_btn_quarterly.setEnabled(true);
                    remove_ads_btn_halfyearly.setEnabled(true);
                    remove_ads_btn_yearly.setEnabled(true);
                } else {
                    // handle error
                }
            }
        };

现在，我想知道如何自定义我的代码以支付每种类型的订阅，如图所示。当时间段结束时，每个订阅都应该自行激活。

谢谢。

Answer 1

您有两种选择可以将购买时间存储在服务器上(然后在您的应用中使用当前时间对其进行验证)或使用 googleplay androidpublisher api .

在响应中您将获得 PurchasedTime。

{
  "kind": "androidpublisher#productPurchase",
  "purchaseTimeMillis": long,
  "purchaseState": integer,
  "consumptionState": integer,
  "developerPayload": string
}

除此之外..您需要检查查询库存中的每个 SKU(您只消费每月)。

    IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
        public void onQueryInventoryFinished(IabResult result, Inventory inventory) {


            Purchase gasMonthly = inventory.getPurchase(SKU_MONTHLY);
            Purchase gasYearly = inventory.getPurchase(SKU_YEARLY);
            if (gasMonthly != null) {
               mHelper.consumeAsync(inventory.getPurchase(SKU_MONTHLY), mConsumeFinishedListener);
                    mSubscribedTo = true;
            } else if (gasYearly != null) {
               mHelper.consumeAsync(inventory.getPurchase(SKU_YEARLY), mConsumeFinishedListener);
                    mSubscribedTo = true;
            } else {

                    mSubscribedTo = false;
            }

编辑:

how I can know that the subscription days, subscribed packaged after payment?

您将在 mPurchaseFinishedListener/mGotInventoryListener 上获取购买的 sku 项目，将其保存在 sharedpreferences 或服务器上。

用于天数验证。您将从购买中获得购买时间。使用 purchase.getPurchaseTime() 购买，您必须将其存储在本地应用程序或查询购买的 sku 以每次获取时间。
