Unity Android IAP“购买失败，因为购买未正确初始化”

Question

我有什么

IAP 按钮在统一编辑器中运行良好。购买后，我收到调试消息 "ProcessPurchase: PASS. Product: 'full_version'" 。 但当我尝试在设备上进行购买时，按钮不起作用。

在编辑器中购买产品时不会出现任何错误

到目前为止我做了什么

1. 自动初始化 UnityPurchasing 复选框已打开 screenshot from unity IAP catalog
2. 我已检查产品 ID 和价格在 unity 和 Play 控制台中是否相同
3. 我的 IAP 产品在游戏控制台中显示为活动状态IAP in play console
4. 像这样设置无代码 IAP Unity IAP button component

按下设备上的按钮时出现 LogCat 错误

问题是我不明白这个错误是什么意思，以及随后如何解决它。希望得到您的帮助

很遗憾，您正在混合使用无代码和脚本 IAP。您应该完全避免 Codeless IAP，正如您所看到的，它已经有一段时间没有更新并且存在问题。相反，请使用脚本 IAP（仅）。阅读：this forum
