Android Developers: Optimize media playback and maximize reach with Jetpack Media3 APIs

Media consumption accounts for a large portion of user time spent on mobile devices, which requires the playback experience to be flawless, highly efficient and mindful of battery life. Furthermore, users expect these experiences to seamlessly transition across their devices, from phones to living room TVs and beyond.



Explore how architectural updates in Media3 and ExoPlayer power seamless playback across form factors. The discussion centers on crafting responsive interfaces with the Media3 Compose UI toolkit, eliminating buffering in feeds using the new PreloadManager and extending your app to living room screens and Android XR with CastPlayer and spatial audio.
