The Art of Doing: Dive Into Android Development with Kotlin - Putting Data in a View Model

The video tutorial covers the implementation of ViewModel in Android to manage UI-related data lifecycle. It starts with an introduction to ViewModel and its benefits in handling configuration changes. The tutorial then guides through setting up a simple UI layout with TextView and EditText, followed by adding buttons for user interaction. It explains the setup of data binding in the project and demonstrates handling click events for the buttons. Finally, it shows how to use ViewModel to persist data across screen rotations, ensuring data is not lost during configuration changes.
