Android :: Get Icon Of Other Applications (droid)

What I'm doing is getting a list of all the current running processes on the phone. Which I have done by,

private List<RunningAppProcessInfo> process;
private ActivityManager activityMan;
...
activityMan = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
process = activityMan.getRunningAppProcesses();

this works fine. When I call the processName field like

process.get(i).processName;

I get a name like com.android.mail for example.

what I'm trying to do is use this to get access to that application so I can display its icon to the user, but I cant find anything that lets me do this.

I'm testing this app on my hero so the api level is 3 (android 1.5).
