# Render speed limit for a route
> **Note**
>
> This example is a part of the [Navigation SDK Examples](https://github.com/mapbox/mapbox-navigation-android-examples). You can find the values for all referenced resources in the [`res`](https://github.com/mapbox/mapbox-navigation-android-examples/tree/main-v2/app/src/main/res) directory. For example, see [`res/values/strings.xml`](https://github.com/mapbox/mapbox-navigation-android-examples/tree/main-v2/app/src/main/res/values/strings.xml) for `R.string.*` references used in this example. The dependencies can be found [here.](https://github.com/mapbox/mapbox-navigation-android-examples/blob/main/app/build.gradle) The examples use View binding.

/**
* The example demonstrates how to draw speed limit information during active navigation.
*
* 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
*
*
*
*
*
*
* 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 no alternatives.
* - When the example starts, the camera transitions to the location where the route is.
* - Click on Set Route to draw a route line on the map using the hardcoded route.
* - Click on start navigation.
* - You should now see speed limit related information throughout the trip wherever accessible.
* - The speed limit window will not show speed limit values if the data is not available.
*
* Note:
* The example does not demonstrates the use of [MapboxRouteArrowApi] and [MapboxRouteArrowView].
* Kindly look at [RenderRouteLineActivity] example to learn more about route line and route arrow.
