That's how supossed to be. When Activity1 launchs Activity5, Activity1
goes background and can be killed at any time by the system. Now, if
you go to home, Activity5 goes to backgroud. Going back to your
application, Activity5 cames on foreground. Pressing back, Activity1
goes to foreground destroying Activity5.
I think you'll need to redesign as you can't think yourself from where
you are coming to foreground. If you are using only different views,
try thinking on that: using just differents views (if they aren't too
much though).

If you want just play dirty, maybe there's a way to catch the "home"
button press (I don't know if possible) event. But, your activity can
be killed at any time. You can't make assumptions when your activity
is no more visible.
