代码里using了UnityEngine.Purchasing.Security命名空间导致Android打包inject失败

[Mr-sB]

触发场景

• 接入unity IAP包(In App Purchasing)
• CS代码里using了UnityEngine.Purchasing.Security命名空间
• Android打包inject失败

错误日志

解决方案

尝试过将包含"Purchasing"的命名空间从[Hotfix]和[CSharpCallLua]中排除，依然失败。
需要将用到UnityEngine.Purchasing.Security的代码放进单独的程序集，让xlua完全忽略它
