Such files can be stored locally or streamed over the Internet. Jetpack\nMedia3 provides a `Player` interface that defines basic functionality such as\nthe ability to play, pause, seek, and display track information.\n\n`ExoPlayer` is the default implementation of this interface in Media3. Compared\nto Android's `MediaPlayer` API, it adds additional conveniences such as support\nfor multiple streaming protocols, default audio and video renderers, and\ncomponents that handle media buffering. ExoPlayer is easy to customize and\nextend, and can be updated through Play Store application updates.\n| **Tip:** If you are new to ExoPlayer, check out the [Getting started](/guide/topics/media/exoplayer/hello-world) page for an introduction to using ExoPlayer. If you already use the standalone ExoPlayer library, see the [migration guide](/guide/topics/media/media3/getting-started/migration-guide) for instructions on moving to Media3."]]
