vulkan + googlevr crashes

I followed the steps here:

To get a basic daydream app up and running. With these settings, the packaged builds and starts on device (Pixel XL running the latest build of android 7.1), but crashes before it ever displays my test scene.

If I enable just ES2 or ES3.1, the app runs as expected. But if I add vulkan with any other combination (just vulkan, vulkan + es2, vulkan + es3, vulkan + es2 + es3), the app crashes at startup.

I can package up a sample project that reproduces the issue (or a packaged APK if that would be more useful). Thanks!

GoogleVR does not support Vulkan yet.
