If device implementations include support for Vulkan 1.0, they:

[C-1-1] MUST report the correct integer value with the android.hardware.vulkan.level and

android.hardware.vulkan.version feature flags.

[C-1-2] MUST enumerate, at least one VkPhysicalDevice for the Vulkan native API

vkEnumeratePhysicalDevices() .

[C-1-3] MUST fully implement the Vulkan 1.0 APIs for each enumerated VkPhysicalDevice .

[C-1-4] MUST enumerate layers, contained in native libraries named as libVkLayer*.so in the

application package’s native library directory, through the Vulkan native APIs

vkEnumerateInstanceLayerProperties() and vkEnumerateDeviceLayerProperties() .

[C-1-5] MUST NOT enumerate layers provided by libraries outside of the application

package, or provide other ways of tracing or intercepting the Vulkan API, unless the

application has the android:debuggable attribute set as true .

[C-1-6] MUST report all extension strings that they do support via the Vulkan native APIs ,

and conversely MUST NOT report extension strings that they do not correctly support.

[C-1-7] MUST support the VK_KHR_surface, VK_KHR_android_surface,

VK_KHR_swapchain, and VK_KHR_incremental_present extensions.

If device implementations do not include support for Vulkan 1.0, they:

[C-2-1] MUST NOT declare any of the Vulkan feature flags (e.g. android.hardware.vulkan.level ,

android.hardware.vulkan.version ).

[C-2-2] MUST NOT enumerate any VkPhysicalDevice for the Vulkan native API

vkEnumeratePhysicalDevices() .

If device implementations include support for Vulkan 1.1, they:

[C-3-1] MUST expose support for the SYNC_FD external semaphore and handle types.

[SR] Are STRONGLY RECOMMENDED to support the

VK_ANDROID_external_memory_android_hardware_buffer extension.

7.1.4.3 RenderScript

[C-0-1] Device implementations MUST support Android RenderScript , as detailed in the

Android SDK documentation.

7.1.4.4 2D Graphics Acceleration

Android includes a mechanism for applications to declare that they want to enable hardware

acceleration for 2D graphics at the Application, Activity, Window, or View level through the use of a

manifest tag android:hardwareAccelerated or direct API calls.

Device implementations:

[C-0-1] MUST enable hardware acceleration by default, and MUST disable hardware

acceleration if the developer so requests by setting android:hardwareAccelerated="false”

or disabling hardware acceleration directly through the Android View APIs.

[C-0-2] MUST exhibit behavior consistent with the Android SDK documentation on

hardware acceleration .

Android includes a TextureView object that lets developers directly integrate hardware-accelerated

OpenGL ES textures as rendering targets in a UI hierarchy.
