在近期开发 AR 程序时，受限于公司测试设备的匮乏，笔者只能使用一台多年前的旧机型 Huawei P30 进行真机调试。相比之下，我个人的 vivo X Fold5 在 AR 能力上远不及这台 P30（新不如旧，原因未知），因此它成为了本次适配的核心测试机。

值得一提的是，这台 Huawei P30 已升级至鸿蒙系统。理论上，由于众所周知的历史原因，鸿蒙设备无法安装谷歌的 ARCore 框架。但诡异的是，这台早期机型却成功安装了该框架。推测是早年 ARCore 曾对 P30 做过专项适配，而在华为后续的新机型中才彻底切断了支持。这种由于历史遗留问题导致的兼容性断层，确实给开发者的环境搭建带来了不少困扰。

然而，真正的挑战出现在应用运行阶段。我的 Unity 工程集成了部分第三方原生库以及自研的底层库。在我的 vivo X Fold5 上，程序运行一切正常；但在切换到这台 Huawei P30 时，应用却直接崩溃，并抛出了以下异常：
