Forcing an android app to quit when the 'home' button is clicked?

Thanks Jacquie - you’re right, suspendStack doesn’t seem to be supported
by either iOS or Android so no joy there. I wanted the app to quit when
the user navigated away from it because I have a routine that attempts to
sync files that have been saved but not uploaded each time the app starts
up. If the app stays running then that sync script doesn’t run. I can work
around this but it would be nice to know when the app loses focus.
