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