This video tutorial introduces the concepts of view and data binding in Android development using a diaper tracker app. It guides viewers through setting up a new project, enabling data binding in the Gradle file and layout, and creating a binding object in the main activity. The tutorial also covers implementing click listeners for buttons and writing functions to handle diaper changes and update the UI.

What is the primary purpose of using data binding in Android development?
