For your ARCore app deployed on Android, you can use the following utilities to help with debugging:
Call logging - ARCore API calls logged to the Android device log help troubleshoot runtime behavior and performance issues in your app.
Performance overlay - ARCore can provide a real-time overview of an app’s performance with statistics on CPU, memory, and other system resource usage in an overlay that displays on the app. The performance overlay also provides a CPU usage breakdown for individual ARCore features.
