TrackGroupArray

@UnstableApi
public final class TrackGroupArray implements Bundleable

An immutable array of TrackGroups.

This class is typically used to represent all of the tracks available in a piece of media. Tracks that are known to present the same content are grouped together (e.g., the same video feed provided at different resolutions in an adaptive stream). Tracks that are known to present different content are in separate track groups (e.g., an audio track will not be in the same group as a video track, and an audio track in one language will be in a different group to an audio track in another language).
