Yes, works on krillin, doesn't work on arale.

Unity8 uses the android-headers package to accomplish that for krillin. That gives us the following options to initialize lights:

LIGHT_ID_BACKLIGHT
LIGHT_ID_KEYBOARD
LIGHT_ID_BUTTONS
LIGHT_ID_BATTERY
LIGHT_ID_NOTIFICATIONS
LIGHT_ID_ATTENTION

Krillin works fine with LIGHT_ID_NOTIFICATIONS, however, arale doesn't. I have tried with all the others and the only one that actually does something on arale is LIGHT_ID_BACKLIGHT, which is obviously not what we want. If we can talk to the lights at all, this probably needs to be fixed on the android side of things.
