Service doesn't run on ChromeBook when app is closed.

[davefinney]

The service below runs on a phone both with the app open and when the app is closed.

The service does run on ChromeBook when the app is open (full-screen, small or minimised), but stops when the app is closed.

Services clearly do run on ChromeBooks with apps closed, so does the service require something extra to work on ChromeBooks?

ABC counts seconds from app start.
Stat counts minutes from service start.
