Red screen

Just show entire red screen without any toolbars, with maximum brightness. Useful for signaling some emergency.

Features:

  • Hiding everything else (immersive mode)
  • Setting brightness to maximum
  • Showing the application atop of lock screen (when activated from some gesture, etc.)
  • Overridable colour (as intent parameter)

You can trigger it from console with am start -n org.vi_server.red_screen/org.vi_server.red_screen.RedScreenActivity command. For overriding colour use parameter like -e colour yellow.

Exit with "Back" button, not with "Home" (due to brightness wakelock).

See Github releases for pre-built redscreen.apk signed with a debugging key.
