The AudioPresentation class encapsulates the information that describes an audio presentation which is available in next generation audio content. Used by[MediaExtractor](https://developer.android.com/reference/android/media/MediaExtractor)[MediaExtractor.getAudioPresentations(int)](https://developer.android.com/reference/android/media/MediaExtractor#getAudioPresentations(int))and[AudioTrack](https://developer.android.com/reference/android/media/AudioTrack)[AudioTrack.setPresentation(AudioPresentation)](https://developer.android.com/reference/android/media/AudioTrack#setPresentation(android.media.AudioPresentation))to query available presentations and to select one, respectively. A list of available audio presentations in a media source can be queried using[MediaExtractor.getAudioPresentations(int)](https://developer.android.com/reference/android/media/MediaExtractor#getAudioPresentations(int)). This list can be presented to a user for selection. An AudioPresentation can be passed to an offloaded audio decoder via[AudioTrack.setPresentation(AudioPresentation)](https://developer.android.com/reference/android/media/AudioTrack#setPresentation(android.media.AudioPresentation))to request decoding of the selected presentation. An audio stream may contain multiple presentations that differ by language, accessibility, end point mastering and dialogue enhancement. An audio presentation may also have a set of description labels in different languages to help the user to make an informed selection. Applications that parse media streams and extract presentation information on their own can create instances of AudioPresentation by using[AudioPresentation.Builder](https://developer.android.com/reference/android/media/AudioPresentation.Builder)class.

## Public methods
### describeContents
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
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)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#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](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)
|
### equals
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean equals (Object o)
```
Indicates whether some other object is "equal to" this one.
The`equals`method implements an equivalence relation on non-null object references:
- It is*reflexive* : for any non-null reference value`x`,`x.equals(x)`should return`true`.
- It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`.
- It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`.
- It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified.
- For any non-null reference value`x`,`x.equals(null)`should return`false`.
An equivalence relation partitions the elements it operates on into*equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters ||
|-----|--------------------------------------------------------------|
| `o` | `Object`: the reference object with which to compare.

|-----------|-------------------------------------------------------------------------------|
| `boolean` | `true`if this object is the same as the obj argument;`false`otherwise.

|
### hasAudioDescription
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

|
### hasSpokenSubtitles
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean hasSpokenSubtitles ()
```
Indicates whether spoken subtitles for the visually impaired are available.

| `boolean` | `true`if spoken subtitles are available.
|
### hashCode
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int hashCode ()
```
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by[HashMap](https://developer.android.com/reference/java/util/HashMap).
The general contract of`hashCode`is:
- Whenever it is invoked on the same object more than once during an execution of a Java application, the`hashCode`method must consistently return the same integer, provided no information used in`equals`comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the[equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object))method, then calling the`hashCode`method on each of the two objects must produce the same integer result.
- It is*not* required that if two objects are unequal according to the[equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object))method, then calling the`hashCode`method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
| Returns ||
|-------|-------------------------------------------|
| `int` | a hash code value for this object.
|
### toString
Added in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public String toString ()
```
Returns a string representation of the object.
| Returns ||
|--------------------------------------------------------------------|-----------------------------------------------|
| [String](https://developer.android.com/reference/java/lang/String) | a string representation of the object.
|
### writeToParcel
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void writeToParcel (Parcel dest,
int flags)
```
