Ensure *Play Services for AR* version 1.29.0 or higher is installed on the target device.\n2.

Leaving this tag\n in place in your published app could result in unexpected behavior in the\n future.\n\nIf the app functions normally, then the app is ready for the changes in November 2022.\n\nTimeline\n--------\n\n| Period | Events |\n| November 2020 (ARCore SDK version 1.20.0) | Deprecate native APIs.
