Step #6: Enabling View Binding

We are going to need to start working with our widgets from Kotlin. There are a variety of options for doing this. The one that we will use in this book is called “view binding”. By enabling view binding, the build tools will code-generate a class that helps us work with our widgets in a type-safe fashion.

To turn this on, add these lines to the android closure in your app/build.gradle file:

  buildFeatures {
    viewBinding true
  }

You can learn more about view binding in the "Binding Your Data" chapter of Elements of Android Jetpack!

When the editor suggests that you sync your Gradle files with the project, go ahead and do that.

NOTE: You will see these lines written elsewhere as:

    buildFeatures {
        viewBinding = true
    }

That was the correct syntax for a while, but Arctic Fox (and its edition of the Android Gradle Plugin) changed the syntax.
