NOTE

This example is a part of the Search SDK for Android sample app. 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.

Besides Address Autofill this example also uses utility class SampleAppUtils.kt and Mapbox Maps SDK. You need to add it as a dependency using the Maps SDK v10 installation instructions.
