/**
 * The example demonstrates how to hide `SpeedLimit`, `RoadNameLabel` and `ActionButtons` in free
 * drive state but show in other states.
 *
 * Before running the example make sure you have put your access_token in the correct place
 * inside [app-preview/src/main/res/values/mapbox_access_token.xml]. If not present then add
 * this file at the location mentioned above and add the following content to it
 *
 * <?xml version="1.0" encoding="utf-8"?>
 * <resources xmlns:tools="http://schemas.android.com/tools">
 *     <string name="mapbox_access_token"><PUT_YOUR_ACCESS_TOKEN_HERE></string>
 * </resources>
 *
 * The example uses replay location engine to facilitate navigation without physically moving.
 *
 * How to use the example:
 * - Start the example
 * - Grant the location permissions if not already granted
 * - Long press on the map to select a destination
