DOOR_POS
What it is
Door position
The maxInt32Value and minInt32Value in VehicleAreaConfig must be defined. All integers between minInt32Value and maxInt32Value must be supported.
The minInt32Value indicates the door is closed. The minInt32Value must be 0. The maxInt32Value indicates the door is fully open.
Values in between minInt32Value and maxInt32Value indicate a transition state between the closed and fully open positions.
This property is not in any particular unit but in a specified range of relative positions.
Some vehicles (minivans) can open the door electronically. Hence, the ability to write this property.
This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.
How the ID is built
A property ID is a 32-bit value packing four fields. Reading 0x16400b00 apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x06000000 | DOOR |
| Type | 0x00ff0000 | 0x00400000 | INT32 |
| Ordinal | 0x0000ffff | 0x00000b00 | 0xb00 |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
int value =
mgr.getIntProperty(VehiclePropertyIds.DOOR_POS, areaId);This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
