I’ve been asked to develop a very simple product display app for distribution in multiple stores.
The tablet will be plugged in and charging on a display unit. The app is ‘always on’ with the app running on full brightness - no screen dimming. I handle this in lua with a call to
system.setIdleTimer( false )
However, after a meeting today with the client, they said that most storekeepers will switch the tablet ‘off’ at night, which means the tablet’s battery will fully discharge overnight, or across a Sunday.
So - is there a way to tell when the tablet is charging / plugged in?
I would like to cause the app and tablet to ‘sleep’ when not charging and then ‘wake’ when the power is switched on again.
