Hi all
I don’t know why hardware back button is not working(on device of wp8). I try many ways but nothing done.
explain to me why(example…:D)
thanks
Hi @tech74,
The “back” button should work (but only that button currently, not other hardware buttons on WP8). We’ll likely need to see your code to help diagnose…
Thanks,

The back key event definitely works on WP8. We have a code example of how to use it here…
http://docs.coronalabs.com/daily/coronacards/wp8/portapp.html#back-key-support
You should also double check your key event listener doesn’t trigger any Lua runtime errors as well that is preventing your back key functionality from working. You can see errors and other log messages (such as from your print statement) in Visual Studio’s “Output” panel while running your app in Visual Studio’s debugger.
plz help me!!!
function BaseScene:enterScene(event)
self.onKeyEvent = function(event)
local phase = event.phase
local keyName = event.keyName
if keyName == “back” then
if phase == “up” then
self:onBackEvent()
end
return true
elseif keyName == “menu” then
if phase == “up” then
self:onMenuEvent()
end
return true
end
return false
end
Runtime:addEventListener(“key”, self.onKeyEvent)
Hi @tech74,
I suggest that you mimic the example that we provide, since it’s been proven to work. Your function setup and usage of “self.*” and other things may be the reason it’s failing.
Best regards,

Try changing this:
if phase == “up” then
to
if phase == “down” then
There doesn’t seem an “up” phase at least not in the Windows 8 Phone simulator.
