OpenXR SDK 1.0.32

OpenXR SDK 1.0.32 (2023-11-29)

This release contains a number of vendor extensions, plus a new ratified
revision to the XR_KHR_loader_init extension that specifies forwarding the
init calls to API layers. Vendors of API layers, primarily on Android, must
verify they can handle being passed XR_NULL_HANDLE for the instance parameter
of xrGetInstanceProcAddr, to avoid bugs when using the updated loader. This
release also contains a number of build system cleanups and fixes. Users of the
Android Gradle Plugin and our official loader AAR file can now use the
OpenXR::headers target just like on desktop: there is now metadata for the
"prefab" tool to generate for CMake both this header/include-only target and the
normal OpenXR::openxr_loader imported library target. The shipped AAR is much
smaller due to stripping debug data from the binaries, which helps in case
application build systems do not automatically strip native binaries. A bug in
the loader Android manifest as shipped in 1.0.31 has also been fixed.

  • Loader Android AAR: Strip binaries before inclusion in AAR, as loader is stable
    (and mostly shared with all platforms) and size difference is substantial.
  • Loader Android AAR: Expose OpenXR::headers prefab imported target just as on
    desktop builds
    (internal MR 2886)
  • Loader Android AAR: Generate a source jar file for completeness.
    (internal MR 2886)
  • Loader Android AAR: Add <uses-sdk> elements to Android loader AAR manifest,
    to prevent the manifest merger from assuming a version < 4 and adding unneeded
    permissions accordingly.
    (internal MR 3029)
    (internal MR 3032)
  • Clean up our CMake build substantially, correcting dependencies and narrowing
    the scope of includes.

    for reuse.

    editors, and improve the experience of editing Python scripts in some editors
    by adding a .env file.
