Position updates during tunnel extrapolation should be treated the same way as regular updates. (For more information on the OnPositionChangedListener, see Positioning section.) If the road element at position contains the tunnel attribute, it implies that the current location is provided by tunnel extrapolation. You can change default configuration file location with STARSHIPCONFIG environment. However, if your application also listens to the onPositionFixChanged() callback from PositioningManager.OnPositionChangedListener, then it receives this callback signifying a position fix change. To get started configuring starship, create the following file. If your application listens to position updates from NavigationManager.PositionListener, there are regular position updates during tunnel extrapolation. It uses the last available position data which contains speed, orientation and GeoCoordinate to estimate the position of your vehicle inside a tunnel. Tunnel extrapolation is also performed internally by NavigationManager. Note: Your application should switch to the navigation. In simulation mode, the map-matched position is simulated along the route with a user-defined speed. SDK for Android can also track the current position and display it on the map without a calculated route. Map Matching is automatically enabled in both navigation mode and tracking mode. Otherwise, navigation operations will not work properly. Go to the location where you saved the Google Maps Android API v2 Samples repository after downloading it. Instead, the application must first download the required map data through the use of MapLoader or MapDataPrefetcher. In Android Studio, select File > New > Import Project.
