Build TV playback apps

Browsing and playing media files is frequently part of the user experience provided by a TV app. Building such an experience from scratch while making sure that it is fast, fluid, and attractive can be challenging. Whether your app provides access to a small or large media catalog, it is important to let users quickly browse options and get to the content they want.

The Android framework provides classes for building user interfaces for these types of apps with the Leanback androidx library. This library provides a framework of classes for creating an efficient and familiar interface for browsing and playing media files with minimal coding. The classes are designed to be extended and customized, so you can create an experience that is unique to your app.

The pages in this section show you how to build a TV app for browsing and playing media content using the Leanback support libraries for TV.
