Question

我在创建renderpass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，然后尝试运行该项目时，我收到此错误消息。有没有办法加载libVkLayer _..._ validation.so文件？

不要链接验证图层。您需要做的就是在apk中包含验证层二进制文件以及您的apk或系统范围路径中的某个位置，然后它只是启用图层以使验证工作。然后由加载程序完成定位和加载库。

如果您正在使用NDK r12（或更高版本），则会包含预先构建的验证图层，并且可以通过gradle轻松添加。请参阅此here的官方文档。

另一种选择是从official repository手动为目标体系结构构建Android验证图层，并将其手动添加到Android版本中。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。

如何链接验证层？
