There is an application on QT C ++ for Android. The task is to deploy the application to full screen. The task was partially solved, he did the whole screen, but there appears a pop-up hint: "To exit full-screen mode, slide your finger down." I would like to turn off this hint too, who knows, tell me, please. Now it is necessary to prohibit the user to close the application. Required:

  1. Remove the android system navigation menu (back, exit to the main menu, etc.) programmatically or via the adb command. And provide for the return of this menu. Technically, if there is an implementation of invoking a command to the console via QT, the option will do. If there is an option on JAVA, write too.
  2. Disable or redefine side volume buttons. Also in any way.
  • and what will you do with the hardware buttons "back" "home"? tape to close? Side volume buttons are redefined easily. I recommend simply making your application a "launcher". - KoVadim
