Android tablet kiosk development

I did this on Samsung Galaxy Tab sm-t330nu

edit the lpm service entry in init.rc from

service lpm /system/bin/lpm
    class charger
    critical


to

service lpm /system/bin/reboot
    class charger
    critical


Result = from powered off state, plug in charger, battery icon displays briefly, then device reboots to normal operation.

to mod your device's service in your init.rc in the 


  on charger


section find that equivalent service.
