Inherited constants

From interface android.os.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(Parcel, int)`: 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)`".

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`MediaFormat`	`getFormat()` Gets the `MediaFormat` of the track.
`String`	`getLanguage()` Gets the language code of the track.
`int`	`getTrackType()` Gets the track type.
`String`	`toString()` Returns a string representation of the object.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

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(android.os.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. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

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.

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. This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
