# Create a line layer

> **Note (legacy): A newer version of the Maps SDK is available**

> This page uses v9.7.1 of the Mapbox Maps SDK. A newer version of the SDK is available. Learn about the latest version, v11.29.0, in the [Maps SDK documentation](https://docs.mapbox.com/android/ja/maps/guides/)
