Unity 游戏在构建后无法运行（MissingMethodException）

Question

Unity 上的游戏可以运行，但当我将其导出到 Android 时，它就停止运行了。当我在终端中构建并运行时，出现以下错误：

Answer 1

这都是关于代码剥离的。如果您想快速解决问题，可以在 Assets 文件夹中创建 link.xml 文件，其中包含以下内容：

<linker>
    <assembly fullname="Unity.ResourceManager" preserve="all" />
    <assembly fullname="Unity.Addressables" preserve="all" />
</linker>

如果您不使用Addressables，则下一个代码：

<linker>
    <assembly fullname="Unity.ResourceManager" preserve="all" />
</linker>

您还可以执行更严格的代码剥离规则。您可以通过此链接找到有关代码剥离的更多信息。
