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