Automatic system updates

The following option has been added in Android 6.0 and its main purpose is to allow device owners to auto-accept a system update:

DevicePolicyManager.setSystemUpdatePolicy (ComponentName admin, SystemUpdatePolicy policy)

SystemUpdatePolicy has been added as well, and you can choose from three options:

• TYPE_INSTALL_AUTOMATIC: update as soon as you get an update

• TYPE_INSTALL_WINDOWED: update should be done within a timed system maintenance and only then, just for 30 days and then return to normal behavior

• TYPE_POSTPONE: postpone updates for up to 30 days and then return to normal behavior afterwards

This can come in handy if you have devices such as showcase tablets or kiosk mode devices, where the update should not mess with the devices' work.
