The Android loader can be found on Maven Central, by adding the following line to your Android app's build.gradle dependencies section:

implementation 'org.khronos.openxr:openxr_loader_for_android:1.1.63'

(There may be a delay of a few hours after release before artifacts are accessible on Maven Central.)

Alternately, the AAR file (plus signature by the dedicated spec editor key and associated POM) are attached to this release.

Similarly, you may include the OpenXR developer API layers in your application through lines like the following, which include them only on debug builds. Only include lines for the layers you want:

debugImplementation 'org.khronos.openxr:apilayer_api_dump:1.1.63'
debugImplementation 'org.khronos.openxr:apilayer_core_validation:1.1.63'
debugImplementation 'org.khronos.openxr:apilayer_best_practices_validation:1.1.63'

The AAR, POM, and signature files for the layers are also attached to this release.

OpenXR SDK (Source) 1.1.62

2026-08-03T20:38:00Z

OpenXR SDK 1.1.62 (2026-07-31)

This release includes a new vendor extension, an important fix to several vendor
extension added in the previous release, a loader design doc clarification, and
some software fixes and cleanup. For extension authors, there are workflow
improvements: extensions may now be developed in their own "fragment" XML file
and referenced from xr.fragmented.xml. Provided tooling processes this file to
generate the all-inclusive xr.xml previously edited directly. This reduces the
merge conflicts seen during extension development and makes review easier,
without requiring changes to tools expecting the conventional combined XML file.

SDK
- Fix: Only include EGL headers in xr_dependencies.h when using EGL or GLES.
  (internal MR 4387)
- Improvement: Add src/common/platform_exports.h to de-duplicate platform
  specific export flags.
  (internal MR 4323)
- Improvement: Add additional description of Android API layer support.
  (internal MR 4373)
- Improvement: Deduplicate .def, .expsym, and .map files used for API
  layers in the SDK.
  (internal MR 4389,
  internal MR 3289)
Registry
- Change: XML registry xr.xml is now checked in after being constructed from
  xr.fragmented.xml and multiple per-extension XML file fragments, for reduced
  conflicts during development. The schema of xr.xml has not changed. Be sure
  to run specification/scripts/merge-registry.sh after editing
  xr.fragmented.xml or one of the fragments, as most tooling still uses the
  merged XML registry.
  (internal MR 4161)
- Chore: Register DXR author ID for The DisplayXR Project.
  (OpenXR-Docs PR 201)
- Fix: Resolve inconsistency between extension numbers for META vendor extensions
  (XR_META_hand_tracking_wide_motion_mode2,
  XR_META_hand_tracking_frequency_hint,
  XR_META_hand_tracking_unextrapolated_poses).
  (internal MR 4380)
- Fix: Add XR_ERROR_LIMIT_REACHED as an valid return for
  xrAcquireEnvironmentDepthImageMETA matching API description.
  (internal MR 4414)
- Improvement: Move XR_ANDROID_trackables to extension fragment XML file.
  (internal MR 4161)
- Improvement: Add explicit type includes for types that are implicitly included
  to improve generated documentation.
  (internal MR 4406,
  internal MR 4413)
- New vendor extension: XR_SONY_swapchain_color_space
  (internal MR 4171)

The Android loader can be found on Maven Central, by adding the following line to your Android app's build.gradle dependencies section:

implementation 'org.khronos.openxr:openxr_loader_for_android:1.1.62'

(There may be a delay of a few hours after release before artifacts are accessible on Maven Central.)

Alternately, the AAR file (plus signature by the dedicated spec editor key and associated POM) are attached to this release.

Similarly, you may include the OpenXR developer API layers in your application through lines like the following, which include them only on debug builds. Only include lines for the layers you want:

debugImplementation 'org.khronos.openxr:apilayer_api_dump:1.1.62'
debugImplementation 'org.khronos.openxr:apilayer_core_validation:1.1.62'
debugImplementation 'org.khronos.openxr:apilayer_best_practices_validation:1.1.62'

The AAR, POM, and signature files for the layers are also attached to this release.

OpenXR SDK (Source) 1.1.61

2026-07-06T16:35:22Z

OpenXR SDK 1.1.61 (2026-07-02)

This release marks the initial publication of the development tool API layers
for easier usage by developers for Android/AOSP-based systems. A small addition
to the reflection headers is also included, along with support for new and
revised vendor extensions.

SDK
- Addition: Build AAR files of development API layers and publish to Maven
  Central on release. A line like
  implementation 'org.khronos.openxr:apilayer_core_validation:1.1.61'
  (or apilayer_api_dump or apilayer_best_practices_validation equivalently)
  will bundle a layer with your application and enable it automatically as an implicit layer.
  (internal MR 4136)
- Loader: Fix: Remove redundant null checks in initializePlatform.
  (internal MR 4261)
Registry
- Fix: Typos in enum value names for XrTrackingOptimizationSettingsHintQCOM.
  Original names left as aliases for source compatibility.
  (internal MR 4186)
- Improvement: XR_LIST_FUNCTIONS_ macros in the reflection header are now
  generated for all features, even those lacking functions.
  (internal MR 4329)
