Let's see if I get this correctly :)

Vulkan 1.0.57 by Mesa 18.0 and Vulkan 1.1 is supported by the 
development branch.

These should work as specified, if you encounter issues please file bugs 
and if possible attach a test to the bug that will trigger the issue.

It *should* work, vulkan is not currently actively tested on Android 
since it is disabled by default in Android IA build. There are also some 
known issues with some dEQP tests not passing but I've been running it 
now and then and many apps such as 3DMark, vulkan samples from 
Imagination and vulkan examples by SaschaWillems have been working fine.
