ARCore Extensions for AR Foundation v1.19.0

Breaking change affecting previously published 32-bit-only apps

Google Play Services for AR (ARCore) has removed support for 32-bit-only ARCore-enabled apps running on 64-bit devices. Support for 32-bit apps running on 32-bit devices is unaffected.

If you have published a 32-bit-only (armeabi-v7a) version of your ARCore-enabled app without publishing a corresponding 64-bit (arm64-v8a) version, you must update your app to include 64-bit native libraries. 32-bit-only ARCore-enabled apps that are not updated may crash when attempting to start an augmented reality (AR) session.

To learn more about this breaking change, and for instructions on how to update your app, see https://developers.google.com/ar/64bit.

Known issues

• Issue 141500087: When using Android Emulator x86_64 system images on macOS with ARCore SDK 1.16.0 or later, Google Play Services for AR will crash. As a workaround, use an x86 system image.

Breaking & behavioral changes

• ARCore Extensions for AR Foundation is now dependent on AR Foundation 4.1.0-preview.5.
  • To migrate your project from AR Foundation 3.x to 4.x, refer to the Migration Guide.
  • As part of this migration, ARCore must be selected as the Android XR Provider when building for Android. To change this setting, go to Edit > Project Settings > XR Plug-in Management, switch to the Android tab, and select ARCore as the Plug-in Provider.
• To support Android 11, ARCore Extensions for AR Foundation now requires Gradle version 5.6.4 or later. For details, refer to Android 11.

New APIs and capabilities

• Overrode Equals(object), GetHashCode(), and added CopyFrom(ARCoreExtensionsConfig) to ARCoreExtensionsConfig.

Deprecations

None.

Other changes

• Updated C# style for non-public variables and methods. For example, private float m_Foo now reads private float _foo and private void _Bar() now reads private void Bar().
• Unity 2019.4.3f1 is now the minimum recommended version for ARCore Extensions. AR Foundation 4.1.0-preview.5 requires minimal Unity version 2019.4.

Bug fixes

• Fixed #13: Spamming errors when running the App on Editor mode.

ARCore Extensions for AR Foundation v1.18.0

Upcoming breaking change affecting previously published 32-bit-only apps

In August 2020, Google Play Services for AR (ARCore) will remove support for 32-bit-only ARCore-enabled apps running on 64-bit devices. Support for 32-bit apps running on 32-bit devices is unaffected.

If you have published a 32-bit-only (armeabi-v7a) version of your ARCore-enabled app without publishing a corresponding 64-bit (arm64-v8a) version, you must update your app to include 64-bit native libraries before August 2020. 32-bit-only ARCore-enabled apps that are not updated by this time may crash when attempting to start an augmented reality (AR) session.

To learn more about this breaking change, and for instructions on how to update your app, see https://developers.google.com/ar/64bit.

Known issues

• Issue 141500087: When using Android Emulator x86_64 system images on macOS with ARCore SDK 1.16.0 or later, Google Play Services for AR will crash. As a workaround, use an x86 system image.

Breaking & behavioral changes

• targetSdkVersion inside the ARCore Android Archive (AAR) file has been updated to API level 29. Specifying a targetSdkVersion in your project's build.gradle or AndroidManifest.xml will override the ARCore value.

Bug fixes

• Fixed Cloud Anchors Privacy link in the CloudAnchors sample app. The incorrect link now redirects to the correct link, so existing apps with the incorrect link don't need to be updated.
