Inherited constants

From class Parcelable Int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. Int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

describeContents

Added in API level 16

open fun describeContents(): Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Return
Int	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

getFormat

Added in API level 19

open fun getFormat(): MediaFormat!

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

getLanguage

Added in API level 16

open fun getLanguage(): String!

Gets the language code of the track.

Return
String!	a language code in either way of ISO-639-1 or ISO-639-2. When the language is unknown or could not be determined, ISO-639-2 language code, "und", is returned.

getTrackType

Added in API level 16

open fun getTrackType(): Int

Gets the track type.

Return

Int

TrackType which indicates if the track is video, audio, timed text. Value is android.media.MediaPlayer.TrackInfo#MEDIA_TRACK_TYPE_UNKNOWN, android.media.MediaPlayer.TrackInfo#MEDIA_TRACK_TYPE_VIDEO, android.media.MediaPlayer.TrackInfo#MEDIA_TRACK_TYPE_AUDIO, android.media.MediaPlayer.TrackInfo#MEDIA_TRACK_TYPE_TIMEDTEXT, android.media.MediaPlayer.TrackInfo#MEDIA_TRACK_TYPE_SUBTITLE, or android.media.MediaPlayer.TrackInfo#MEDIA_TRACK_TYPE_METADATA

toString

Added in API level 16

open fun toString(): String

Return
String	a string representation of the object.

writeToParcel

Added in API level 16

open fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
dest	Parcel: The Parcel in which the object should be written. This value cannot be null.
flags	Int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
