Remove the 'Task Bar'

Is there a way to remove (make invisible) the 'Task Bar' at the bottom of the screen (the one with the back, home and icons on).

I have seen on an android media player the task bar is removed when playing video's, so i was wondering if it is possible with B4A.

The reason i am asking is a company has asked me to create an app, which i have done and they would like the task bar removed.

Thanks
