Example 3 with LineString

use of com.mapbox.services.commons.geojson.LineString in project mapbox-navigation-android by mapbox.

the class NavigationMapRoute method addTrafficToSource.

/**
 * If the {@link DirectionsRoute} request contains congestion information via annotations, breakup
 * the source into pieces so data-driven styling can be used to change the route colors
 * accordingly.
