Application Exit Button

  Not sure if it is Gideros "only". Even if it looks like it works flawlessly, a hard exit via LUA is considered a crash on IOS and I think on Android now too. It would be better to follow the guide lines of Apple and Google on how to exit an app.

  There is no exit function in any iOS App - if you put one in your app will be rejected PERIOD!
  
  Instead respond to the various application lifecycle events and do you state saving / clear up there.

  In the discussion http://www.giderosmobile.com/forum/discussion/281/how-to-terminate-an-application- @atilim says that you shouldn't use os.exit(). Can anyone tell me why (asking as I have only just read that and have been using it in a couple of android apps for some time!).
  Thanks, Pete

  You can technically use it in Android apps and obviously in desktop apps (when that functionality exists) but basically having app's allow themselves to exit is against the Apple mobile interface guidelines - they don't like it so you can't call it - end of story!
  
  Something about it breaking the illusion of an immersive experience - apps should suspend when you press home and then restart in the same place when you restart them (regardless of what happens in the background).

  @techdojo Thanks for the explanation. So it won't cause a problem with my android apps but I ought to sort it to keep in line with conventions.

  @techdojo nice explanation, i think the same way as you <> Please take a look:
  
  Thank you for submitting your application to LG SmartWorld.
  
  We have thoroughly reviewed and tested your application. However, your submitted
  application has failed to our test due to functional failure as below:
  
  Defects:
  
  1. "Exit" button does not exist. And unable to using "back key" on phone.
  
  *Step: Execute app> Back button> Observe result
  
  All devices same with P920.
  We look forward to your continued interest.
  
  This sounds funny but is the Android "Smart" World of LG, so anyway to create a exit/resume app button with this: Application:exit() ? - Thanks;

  Sorry for the bump on the thread but I figured it'd be better to ask it here than to ask a new question.
  
  I want to make an exit button and after reading this thread I wondered if it's still the case that exit buttons shouldn't be in the game, or if it has changed since 2012. Also if you know what's the case for iOS and Android.

  I use application:exit() on android on back button when on main scene, and apps have been approved in every store
