Building Flexible Android Apps with the Fragments API with Java

- Hi, my name is David Gassner. Welcome to this course on using the Android Fragments API to build flexible apps that adapt to different screen sizes. Working in Android Studio, I'll first introduce you to the basic concept of fragments. I'll describe how to define a fragment's layout and how to add it to an activity with XML or Java. I'll then show you how to define multiple layouts for different screens, how to use resource folder names to detect screen sizes and select layouts at runtime and how to pass data back and forth between activities and fragments with arguments and callback methods.

I'll also describe other uses of fragments to manage dialogs, pages managed in the view page or container, and shared preferences. The Fragments API is an important part of any Android developers toolkit. I hope this course helps you get started, building apps that look great on a wide variety of devices.
