AFAIK, it is not possible to undermine the Android OS and prevent your program from being closed down if memory gets low.
However, to run in the background you would want to take a look at Services. To launch an activity from a service you would use the startActivity() method. As for being notified when certain things occur, you would want to take a look at BroadcastReceiver class. Hope that helps you get started in the right direction. A word to the wise though, provide an option to turn off the background stuff... users get really upset if they can't control stuff like whether an app runs in the background. I have an app, called AppSwipe, that will tell you which programs are running in the background and will let you close them. I routinely check it and close apps that I don't want running and wasting my battery life. And if an app gets too annoying with restarting itself after I close it, I uninstall it.... no matter how useful or cool it is.
