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