AppLifecycleTrigger

A trigger that triggers when the life cycle of an app changes.

The state changes that triggers are specified in states. If not specified (default) this trigger will trigger on all AppLifecycleState changes.

Typically used to make sure to collect measures when the app life cycle is changing, e.g., moved to the background or foreground. Some measures - like audio, bluetooth, and health - can only be collected when the app is in the foreground.
