They are NOT two different situations. That's the source of your confusion.
They are both a different app being in front of your activity. You mention the call screen and the launcher, but others are possible as well. Once your activity is no longer visible, onStop() is called. If it later becomes visible, and the instance hasn't been destroyed, then onRestart() will be called. This sequence occurs regardless of just which activity came to the front - and you're not allowed to know about activities of other applications for security reasons. The launcher is just pretty much just another application. The home button just sends the intent that launches it. You can supply a different application for that intent, just like you can supply a different application for any intent. (Not that it's always a good idea). So you don't know -- and I can't see why you'd care -- whether it was the Launcher that came in front and triggered onStop(). But what you COULD do is write your own launcher, if you really wanted to know if the home key was pressed for some reason. I'm not sure you could find out about it until later, though. Maybe. But what would you do with that information? You're being stopped, after all. You don't get to run any UI or anything.
