ARCore SDK for Unity 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.
