title: Kill another process/application programmatically
body: <p>I don't want to get on the discussion of whether a process can be killed by the user, whether it should be done that way or not.</p>
  
  <p>I just want to know how almost every Android player's phone got a '<code>advanced task killer</code>' which kills a process or how is it that the <code>force close</code> (in settings) option works just fine. I have tried many ways to kill a process, but all without result. But when I see these '<code>advanced task killer</code>' I can't figure out what's wrong on my side.</p>
