Scene Graph App quit event

Is there any way I can just block the quit event for a second? Or any walkaround? I need to detect the quit event at least. I want to log the usage to a remote server, let’s say google analytics. For now, as I know, the OnKeyEvent() in the node can not detect the home button pressed. And it seems in the main.brs, the while loop that listens on the messagePort is not working either. It seems that no roSGScreenEvent has happened, the logQuit() was never called.

	while(true)
			msg = wait(0, m.port)
			msgType = type(msg)
			if msgType = "roSGScreenEvent"
				if msg.isScreenClosed() then 
					logQuit()
					return
				end if
			end if
		end while

No, there isn’t.
This is not a scenography issue in particular - it’s Roku one in general.
There is a suggestion on how to fix that already, see here https://forums.roku.com/viewtopic.php?f … 30#p487482
Waiting for Roku* to chime in, I suppose. Sheesh, can’t believe it’s been over a year?!

Thank you EnTerr, the way I can image is that at least I can record the time of the app quit. And try to send usage event when the app restarts next time.
I worked on android TV the leanback library before, they all support the background activities. Hope Roku will think about it. This is a common usage case indeed.

Most all mobile and media platforms support exit events, indeed. In fact i can’t think of one that doesn’t.
It’s entirely possible Roku already implemented that a year ago, just forgot to tell us, the “little people”. It has happened before (cue formatJSON(), some ECP commands, getPng()… ).

This page is confusing:
https://sdkdocs.roku.com/display/sdkdoc/roSGScreenEvent

It makes it look like you can intercept the close event, but when the home button is pressed the app doesn’t get any events
