C Specification

To determine the memory parameters to use when importing an Android hardware buffer, call:

VkResult vkGetAndroidHardwareBufferPropertiesANDROID(
    VkDevice                                    device,
    const struct AHardwareBuffer*               buffer,
    VkAndroidHardwareBufferPropertiesANDROID*   pProperties);

Parameters

  • device is the logical device that will be importing buffer.

  • buffer is the Android hardware buffer which will be imported.

  • pProperties is a pointer to a VkAndroidHardwareBufferPropertiesANDROID structure in which the properties of buffer are returned.

Description

Valid Usage
  • buffer must be a valid Android hardware buffer object with at least one of the AHARDWAREBUFFER_USAGE_GPU_* flags in its AHardwareBuffer_Desc::usage

Valid Usage (Implicit)
  • device must be a valid VkDevice handle

  • buffer must be a valid pointer to a valid AHardwareBuffer value

  • pProperties must be a valid pointer to a VkAndroidHardwareBufferPropertiesANDROID structure

  • VK_SUCCESS

On failure, this command returns
