Location context

VERSION 0.12.0

Navigation SDK for Android is only available upon request. Contact us to get started.

The detailed information about a current location on the road is called the location context.

Every location update that comes from LocationProvider to TomTomNavigation is map-matched.

The map-matched locations are then used as input for LocationContextProviderEngine, which returns a LocationContext object.

LocationContext consists of:

  • speed - This is the current Speed, or null if it is unknown.
  • speedLimit - This is the SpeedLimit.
  • address:
    • streetName - The street name.
    • city - The city name.
    • countryName - The country name.
    • countryCode - This is the three-character ISO 3166-1 alpha-3 country code.
  • road:
    • functionalRoadClass - This indicates the relative importance of the road within the routing network. Regular values are in range [0, 7], where lower numbers indicate more important, faster roads.
    • isTunnel - This indicates whether the location is in a tunnel.
    • isUnderpass - This indicates whether the location is on an underpass.
    • roadType - This is the type of the current road, see TypeOfRoad.
    • isLeftHandDriving - This indicates whether the driving side on the current road is left-handed.

The extracted LocationContext is sent to LocationContextUpdatedListener.

1val locationContextUpdatedListener = object : LocationContextUpdatedListener {
2 override fun onLocationContextUpdated(locationContext: LocationContext) {
4 }

To remove a previously-added LocationContextUpdatedListener, use the TomTomNavigation.removeLocationContextUpdatedListener(LocationContextUpdatedListener) method.
