RichardC and String are correct. You can't and shouldn't do this. Re-design your app so that the user does not need to push a GUI to the front at any possible given time.
Also, your background service that waits in the background may have been killed by the Android OS due to low memory or low resource; It may not even be running when your network-event happens.... If you did manage to have your activity pop to the foreground without any user interaction and then put your app on the market, expect quite a few bad comments. Why the phone-dialer can get to the foreground automatically: "It's a phone!" Even the SMS and voice-mail notifications don't automatically show a UI. They show notifications.
