Public methods

getFormat

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

Returns
`MediaFormat`

getLanguage

public String getLanguage ()

getTrackType

Added in Android Q

public int getTrackType ()

Gets the track type.

Returns
`int`	TrackType which indicates if the track is video, audio, timed text.

toString

Added in Android Q

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.
