title: How to prevent user from closing application - Android 4.0.3
body: <p>So my question is: If is possible to prevent user from closing application. </p>
  
  <p>Problem is because i can't hide action bar and i use tablet only for work time registration. So if someone press home button or back button is that not acceptable. </p>
  
  <p>So i wonder if i could somehow handle onclose event? </p>
  
  <p>Is it possible to open application in fullscreen (with no action bar)?</p>
