Request routes outside Drop-In UI using Navigation View
Note
This example is a part of the Navigation SDK Examples. You can find the values for all referenced resources in the res directory. For example, see res/values/strings.xml for R.string.* references used in this example. The dependencies can be found here.The examples use View binding.See setup documention if necessary.

/**
* The example demonstrates how to use [MapboxNavigationApp] to request routes outside [NavigationView]
* and transition [NavigationView] to active navigation state.
*
* 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 anywhere on the map
* - NavigationView should transition to active guidance
