Public constructors

TrackInfo

public TrackInfo (int id, 
                int type, 
                MediaFormat format)

Constructor to create a TrackInfo instance. Note: The default value for isSelectable() is false.

`id`	`int`: id of track unique across `MediaItem`s
`type`	`int`: type of track. Can be video, audio or subtitle
`format`	`MediaFormat`: format of track

TrackInfo

public TrackInfo (int id, 
                int type, 
                MediaFormat format, 
                boolean isSelectable)

Constructor to create a TrackInfo instance.

Parameters
`id`	`int`: id of track unique across `MediaItem`s
`type`	`int`: type of track. Can be video, audio or subtitle
`format`	`MediaFormat`: format of track
`isSelectable`	`boolean`: whether track can be selected via `SessionPlayer.selectTrack(TrackInfo)`.

Public methods

equals

public boolean equals (Object obj)

Parameters
`obj`	`Object`

Returns
`boolean`

getFormat

public MediaFormat getFormat ()

Gets the MediaFormat of the track. If the format is unknown or could not be determined, null is returned.

Returns
`MediaFormat`

getId

public int getId ()

Gets the id of the track. The id is used by SessionPlayer.selectTrack(TrackInfo) and SessionPlayer.deselectTrack(TrackInfo) to identify the track to be (de)selected. So, it's highly recommended to ensure that the id of each track is unique across MediaItems to avoid potential mis-selection when a stale SessionPlayer.TrackInfo is used.

Returns
`int`	id of the track

getLanguage

public Locale getLanguage ()

Gets the language code of the track.

Returns
`Locale`	`Locale` which includes the language information

getTrackType

public int getTrackType ()

Gets the track type.

Returns
`int`	MediaTrackType which indicates if the track is video, audio or subtitle

hashCode

public int hashCode ()

Returns
`int`

isSelectable

public boolean isSelectable ()

Whether the current track can be selected via SessionPlayer.selectTrack(TrackInfo) or not.

Returns
`boolean`	true if the current track can be selected; false if otherwise.

toString

public String toString ()

Returns
`String`
