如何链接验证层?

Question

我在创建渲染通道时遇到了一些麻烦，所以我想启用一些验证层。但是当我将它们添加到 CMakeLists.txt 文件，然后尝试运行项目时，我收到此错误消息。有没有办法加载libVkLayer_..._validation.so文件？

不要链接验证层。您需要做的就是将验证层二进制文件与 apk 一起包含在您的 apk 中或系统范围路径中的某个位置，然后它只是使层能够使验证工作。然后由加载器完成库的定位和加载。

如果您使用的是 NDK r12(或更高版本)，则包含预构建的验证层，并且可以通过 gradle 轻松添加。请参阅此处的官方文档。

另一种选择是从官方存储库手动为您的目标架构构建 Android 验证层，并将其手动添加到您的 Android 构建中。虽然这需要更多的努力，但您始终可以获得最新的验证功能。
