Vulkan is not officially supported right now. What you can try is using Vulkan to OpenGL interop and interfacing with the Oculus SDK via OpenGL. I'm not sure exactly how this works in terms of the code, but I was told it should be possible (at least for PC, not 100% sure about mobile).
Since mobile devices typically don't distinguish the GPU 'device' memory pool from the 'system' memory pool, you may be able to get reasonable performance by doing copy from the rendered image to a mappable memory buffer via `vkCmdCopyImageToBuffer` and then uploading it to a GL texture for submitting to the Oculus SDK.
Sorry, I forgot to follow up. Vulkan is not supported on mobile right now.
ETA? It's been a year. I need to know if Vulkan on mobile will ever be supported natively, otherwise I might have to switch over to Daydream exclusively.

If Vulkan is a hard requirement for you to do VR development, then go do it in Daydream, and port it to Gear VR when they add support for it (like they did for their desktop SDK). The way the Oculus Mobile SDK works means they need Vulkan to add extensions for some things. I never got clarification what Gear VR is doing vs. Daydream that requires those extensions, though.
