I am using a webview to display operational data on an overhead screen using series MK802IIIS/MK802IV devices. I want to hide the navigation bar from view. Originally I used ICSControls which worked on the early device releases. Now they have a later firmware version and no longer respond to the ICSControls commands. The navigation bar appears at the bottom of the screen with the icon that hides it displayed to the right of the power off soft button. Is there a method to simulate clicking on the "hide navbar icon" so that the bottom bar is blank?
