How to listen for system event

[kavery]

How do you listen for 'system events'? For example when an android build pauses.

"you need to listen to the system event "APPLICATION FOCUS" and or "APPLICATION PAUSE"

Thanks

So say you want a State to be 'triggered' when a certain event happens like APPLICATION FOCUS. Just right-click on the State you want to be 'activated', click "Add Global Transition > System Events > APPLICATION FOCUS" etc. Whole bunch of useful events in there.
