The Art of Doing: Dive Into Android Development with Kotlin - Counter App with View Binding Part 2

The video tutorial covers the implementation of a change number function in an app, focusing on increment and decrement operations using a binding object. It explains how to handle user input, perform mathematical operations, and update UI elements. The tutorial also demonstrates creating a hide keyboard function and using bundles for data persistence during screen rotations. The app is tested to ensure functionality, and the benefits of view binding over findViewById are highlighted. The video concludes with a brief introduction to data binding, which offers more capabilities than view binding.
