Callback

Subscribe to changes in vehicle state values by registering and unregistering a listener with registerXxx and unregisterXxx. When a registered value changes, it is delivered to the listener's onXxxUpdated method. Failures are delivered to onFailed. For obtaining a domain object, see Obtaining a domain object. For detailed API specifications, see API Reference.

The following example assumes that the Vehicle instance (vehicle) has already been initialized.

Kotlin

// Create callback listener
val callbackListener = object : DoorPositionListener {
  override fun onPositionUpdated(pos: Int?) {
    // do something
  }

  override fun onFailed(e: Exception) {
    // do something
  }
}

val door = vehicle.getDoor()

// register callback
door.registerDoorPosition(
  doorPositionListener = callbackListener
)
// unregister callback
door.unregisterDoorPosition(
  doorPositionListener = callbackListener
)

Java

// Create callback listener
DoorPositionListener callbackListener = new DoorPositionListener() {
  @Override
  public void onPositionUpdated(@Nullable int pos) {
    // do something
  }

  @Override
  public void onFailed(@NonNull Exception e) {
    // do something
  }
};

Door door = vehicle.getDoor();

// register callback
door.registerDoorPosition(callbackListener);

// unregister callback
door.unregisterDoorPosition(callbackListener);
