【问题描述】：

我尝试使用 Unity 为 Android 构建一个最小的 AR 示例。我刚刚添加了一个默认的ARSession 和ARSession Origin 组件，以及一个普通的立方体。为 Android 构建时，应用启动，请求摄像头权限，然后因段错误而崩溃

这发生在 Mono 和 IL2CPP 构建中。我使用的是华为智能手机，因此我不得不使用 apk 安装 Google AR 服务，因为它在 Play 商店中被屏蔽了。

还有其他人遇到过这个问题吗？

【问题讨论】：

你有没有想过这个问题？我也有同样的问题？？？？
很遗憾没有。仍然希望得到答案

【解决方案1】：

我正在使用 Xperia 1 II 并且遇到了同样的问题。我试过Step 2 of this codelab，但在权限检查后崩溃了。

将Target Architectures 更改为ARM64 解决了它。

团结 2021.2.5f1
AR 基础 4.2.1
ARCore XR 插件 4.2.1
