Comprehensive Android Developer Bootcamp - ScreenSize Utility Class

The video tutorial guides viewers through creating a Java class called Screen Utility, which helps determine the screen dimensions of a device at runtime. The tutorial covers organizing code with packages, defining class variables, creating a constructor, and using Android's display metrics to calculate screen dimensions. It also demonstrates implementing getters and using the Screen Utility class within a fragment to log screen width. The tutorial emphasizes the importance of this utility in adapting user interfaces based on device screen size.
