/**
* The example demonstrates how to add your own long click listener on the `MapView` and disable
* `NavigationView` from handling it.
*
* 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>
*
* How to use the example:
* - Start the example
* - Long click on the `MapView`
