Closing the app when you are several screens deep

Archived
1

I’d like to close my app/channel in some cases, i.e. when I detect an abuse after showing an error message! In some cases I might be several levels/screens deep and I don’t keep global references to all my open screens. So when I wanted to exit the app, some of them stayed open! I didn’t find any references to exiting the program! I appreciate your help.

usually the end statement will kill your channel.

Does the END statement still apply to devices with newer firmware (4.8-5)? I cannot forcibly make a channel exit with a Roku 3 running 5.0.7070

I need the channel to exit once the device is no longer linked to an account.

If nothing else works, you can send yourself a keypress/Home ECP command.


ipaddrs = CreateObject("roDeviceInfo").GetIPAddrs()
if ipaddrs.eth0 <> invalid then
   ipaddr = ipaddrs.eth0
end if
if ipaddrs.eth1 <> invalid then
   ipaddr = ipaddrs.eth1
end if
xfer = CreateObject("roURLTransfer")
url = "http://"+ipaddr+":8060/keypress/Home"
xfer.SetUrl(url)
xfer.PostFromString("")

I just tested on 5.0b7070 and End worked for me.

I don’t know if it makes a difference, but I add the following to the same file as RunUserInterface, and just call ExitUserInterface anytime I need to close the channel programmatically, so technically I’m calling End from the global context instead of local:

Sub ExitUserInterface()
    End
End Sub

Just tried above with no luck. Does it matter where/how ExitUserInterface() is called?

It shouldn’t. I use it exactly how it sounds like you’re wanting to. As soon as the user chooses to unlink their box, I exit the channel.

ShowMessageBox("Account Unlinked", "Your account has been unlinked.  The channel will now close.  Please relaunch it to link your player again.")
ExitUserInterface()

Thanks, I will experiment more with it tomorrow.

For some reason this just won’t work…


Sub ExitUserInterface()
    End
End Sub

I’ve tried using the following workaround, but this doesn’t appear to work except for on my newest Roku running firmware 5+.


Function forceExitChannel() As Dynamic

	ipaddrs = CreateObject("roDeviceInfo").GetIPAddrs()
	if ipaddrs.eth0 <> invalid then
	   ipaddr = ipaddrs.eth0
	end if
	if ipaddrs.eth1 <> invalid then
	   ipaddr = ipaddrs.eth1
	end if
	xfer = CreateObject("roURLTransfer")
	url = "http://"+ipaddr+":8060/keypress/Home"
	xfer.SetUrl(url)
	xfer.PostFromString("")
	
End Function

Any other suggestions?

Well, the normal approach is to just return through your screens until you return from your entry point. Make each of the screen’s functions return a special value that is checked by the caller, which then returns a special value to its caller, etc.

The stop statement will terminate your channel, but this is not a recommended approach. It makes your channel appear to have crashed. I don’t think this actually has any detrimental effect right now but it’s not recommended.
