Constructs a new TrackInfo instance with the specified track details.
Parameters
tracks
A list of Bundle objects, each containing metadata for a track.

selected Index
The index of the currently selected track in the list, or a negative value if no track is selected.
track Type
An integer representing the type of tracks: "SandboxedPlayer.TRACK_TYPE_VIDEO" for video, "SandboxedPlayer.TRACK_TYPE_AUDIO" for audio, or "SandboxedPlayer.TRACK_TYPE_TEXT" for text.
