如何升级安卓InAppBilling /降级订阅？ [英] How to upgrade/downgrade subscriptions in Android InAppBilling?

问题描述

我花了一周时间寻找解决方案，升级/降级订阅Android上的 InAppBilling 。

I spent a week looking for solution to upgrade/downgrade subscriptions on Android InAppBilling.

有关于这个功能的参考页面：<一href="http://developer.android.com/google/play/billing/billing_reference.html">http://developer.android.com/google/play/billing/billing_reference.html

There's a reference page about this function: http://developer.android.com/google/play/billing/billing_reference.html

谷歌表示，我们可以用 getBuyIntentToReplaceSkus（）的方法，但我不能发现有关在其签名的任何文件。我也无法看到它在 IInAppBillingService.aidl 文件，谷歌提供的。

Google said that we could use getBuyIntentToReplaceSkus() method, but I couldn't found any documentation about that in its signature. I can't also see it in IInAppBillingService.aidl file that Google provided.

有没有一个谁可以帮我吗？

Is there any one who may help me?

推荐答案

首先感谢AIDL文件。

at first thanks for aidl file.

但对我来说，这是行不通的。我总是得到一个错误code 5：

But for me it is not working. I always get an error code 5:

提供的API参数无效。这个错误也可能表示   该应用程序未正确签名或正确地设置为   在应用内计费在谷歌播放，或者没有必要   在其清单的权限

Invalid arguments provided to the API. This error can also indicate that the application was not correctly signed or properly set up for In-app Billing in Google Play, or does not have the necessary permissions in its manifest

我不认为权限是错误的或者未正确签署的所有 其他的付款请求工作。

I don't think that the permissions are wrong or it is not correctly signed as all other payment requests work.

这是我的code：

List<String> subs = new ArrayList<>();
subs.add(current_sub);
buyIntentBundle = mService.getBuyIntentToReplaceSkus(3, "package", subs,
       key, "subs", getResources().getString(R.string.developer_payload));

您如何执行升级的要求还是你看到任何错误在我的要求吗？

How do you execute an upgrade request or do you see any error in my request?
