Public methods

describeContents

added in API level 16
public int describeContents ()

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(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

getFormat

added in API level 19
public MediaFormat getFormat ()

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

Returns
MediaFormat

getLanguage

added in API level 16
public String getLanguage ()

Gets the language code of the track.

Returns
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
public int getTrackType ()

Gets the track type.

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

Value is MEDIA_TRACK_TYPE_UNKNOWN, MEDIA_TRACK_TYPE_VIDEO, MEDIA_TRACK_TYPE_AUDIO, MEDIA_TRACK_TYPE_TIMEDTEXT, MEDIA_TRACK_TYPE_SUBTITLE or MEDIA_TRACK_TYPE_METADATA.

toString

added in API level 16
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.

writeToParcel

added in API level 16
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
