SEAT_OCCUPANCY

What it is

Seat Occupancy

Indicates whether a particular seat is occupied or not, to the best of the car's ability to determine. Valid values are from the VehicleSeatOccupancyState enum.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x15400bb0 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x05000000	SEAT
Type	0x00ff0000	0x00400000	INT32
Ordinal	0x0000ffff	0x00000bb0	0xbb0

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

int value =
        mgr.getIntProperty(VehiclePropertyIds.SEAT_OCCUPANCY, areaId);

This property is read-only — writes are rejected. It fires a callback whenever the value changes.
