How do Task Managers kill apps?

First of all I know it's bad to use a task manager/killer in Android and all that, but what I was wondering is how do task managers like

Advanced Task Killer
kill other applications?

I wanted to develop a simple application that would do this, just for the learning experience.

I tried executing the Linux command kill pid from my application but it didn't work, maybe it requires root?

So, how do I accomplish this from my application? I have a simple ListActivity that shows the currently running tasks and when a user long-presses an item I want to kill that task.

Process.sendSignal(pid, Process.SIGNAL_KILL);

To completely kill the process, it's recommended to call:


before sending the signal.
