Clean a device

How to tidy a local Android device that's been cluttered with downloads or addMedia runs

Successive runs of flows that either use addMedia to import images, or that download files, can leave your device in an inconsistent state for the next run.

A member of the Maestro Slack community, AJ Owens, came up with a recipe for cleaning up thier Android emulator of leftover files by driving the Files app that's installed on every emulator.
