Android Data Binding is a support library that allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically[1]. It generates binding classes at compile time for layouts and allows you to bind objects to UI elements[2].
Some key points about Android Data Binding:
It makes code simpler and easier to maintain by removing UI frameworks called in the activity[4]
It allows classes and methods to observe changes in data and make objects and collections observables[4]
It converts queries directly into objects, checks errors in queries at compile-time, and is capable of persisting Java POJOs[4]
It provides automatic synchronization of data between the View and the ViewModel, reducing the need for manual updates and event handling[5]
