Not sure what you meant by that - mobile apps don't have main() or exit(), they are driven by onThingsHappen(Event event) calls. When the OS decides to call `onYourAppIsResumedFromAltTab(context SwappedOutMemoryContent)` instead of `onYourAppWasJustLaunched(void)`, your app can resume functioning. The former is more likely to happen on devices with larger RAM space. You as an app developer don't have full control over it, unlike how it is(used to be!?) with Win32 apps.

As a user, I can swipe up and hold from my home screen (depends on your launcher probably) and "swipe away" the apps I want to actually close, as in remove from the background. Not all of them comply, though.
