How to get a PERMANENT application notifier in the status bar?

I searched on the Internet alot but cant find a proper answer to this.

I have used apps like 3G watchdog and Advanced task killer on my android phone. I noticed that they always have an icon up when the status bar is minimized and also have a notification( Upon clicking opens the app) which cant be cleared from the status bar.

  • find out which activity started my activity?
  • How to resolve the error “ cannot be resolved” when I using the android file '',
  • I like to use something like this in my app.

    I know how to get an image and everything in the status bar, but how to keep one that cant be cleared till my app is running in the background and is not explicitly turned off is a problem.

    Please Help.Thanks.
