C Specification

To create an image with an external format, add a VkExternalFormatANDROID structure in the pNext chain of VkImageCreateInfo. VkExternalFormatANDROID is defined as:

// Provided by VK_ANDROID_external_memory_android_hardware_buffer
typedef struct VkExternalFormatANDROID {
    VkStructureType    sType;
    void*              pNext;
    uint64_t           externalFormat;
} VkExternalFormatANDROID;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • externalFormat is an implementation-defined identifier for the external format


If externalFormat is zero, the effect is as if the VkExternalFormatANDROID structure was not present. Otherwise, the image will have the specified external format.
