Description
The VK_KHR_android_surface
extension is an instance extension.
It provides a mechanism to create a VkSurfaceKHR object (defined by
the VK_KHR_surface
extension) that refers to an
ANativeWindow, Android’s native surface type.
The ANativeWindow represents the producer endpoint of any buffer
queue, regardless of consumer endpoint.
Common consumer endpoints for ANativeWindows
are the system window
compositor, video encoders, and application-specific compositors importing
the images through a SurfaceTexture
.

Issues
1) Does Android need a way to query for compatibility between a particular physical device (and queue family?) and a specific Android display?
RESOLVED: No. Currently on Android, any physical device is expected to be able to present to the system compositor, and all queue families must support the necessary image layout transitions and synchronization operations.
