title: Android popup on top of desktop view
body: <p>My app contains only one activity and I want it to be opened as a small sized activity on top of the current active activity.</p>
  
  <p>For example, if the app has a shortcut on the desktop and the user activates it then the main activity will open on top of the main desktop view in a small size (deviceHight / 2, deviceWidth / 2) box. If the app clicked from the app drawer the the drawer view will be visible behind the app activity.</p>
  
  <p>Kind of a popup but with no parent activity.</p>
