The normal way you do this on Android is by providing an IBinder object across the processes and using IBinder.linkToDeath.
That said, as others have commented, "stay connected with each other" and "know when an app stops working" are *really* nebulous concepts on Android, and if you are thinking in those terms there is a really good chance what you are trying to do is fundamentally wrong. It's hard to say more though without knowing what you are trying to do.
