/**
* This example demonstrates the usage of the route line and route arrow API's and UI elements.
*
* Before running the example make sure you have put your access_token in the correct place
* inside [app/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 assumes that you have granted location permissions and does not enforce it. However,
* the permission is essential for proper functioning of this example. The example also uses replay
* location engine to facilitate navigation without actually physically moving.
*
* The example uses camera API's exposed by the Maps SDK rather than using the API's exposed by the
* Navigation SDK. This is done to make the example concise and keep the focus on actual feature at
* hand. To learn more about how to use the camera API's provided by the Navigation SDK look at
* [ShowCameraTransitionsActivity]
*
* How to use this example:
* - The example uses a single hardcoded route with alternatives.
* - When the example starts, the camera transitions to the location where the route is.
* - It then draws a route line on the map using the hardcoded route.
* - Click on start navigation.
* - You should now be able to navigate to the destination with the route line and route arrows drawn.
