`public static final Creator<CallAudioState>`	`CREATOR` Responsible for creating AudioState objects for deserialized Parcels.

Public constructors

Public methods
`static String`	`audioRouteToString(int route)` Converts the provided audio route into a human readable string representation.
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

`void`	`writeToParcel(Parcel destination, int flags)` Writes AudioState object into a serializeable Parcel.

Inherited methods

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.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Constants

ROUTE_BLUETOOTH

Added in API level 23

public static final int ROUTE_BLUETOOTH

Direct the audio stream through Bluetooth.

Constant Value: 2 (0x00000002)

ROUTE_EARPIECE

Added in API level 23

public static final int ROUTE_EARPIECE

Direct the audio stream through the device's earpiece.

Constant Value: 1 (0x00000001)

ROUTE_SPEAKER

Added in API level 23

public static final int ROUTE_SPEAKER

Direct the audio stream through the device's speakerphone.

Constant Value: 8 (0x00000008)

ROUTE_STREAMING

Added in API level 34

public static final int ROUTE_STREAMING

Constant Value: 16 (0x00000010)

ROUTE_WIRED_HEADSET

Added in API level 23

public static final int ROUTE_WIRED_HEADSET

Fields

CREATOR

Added in API level 23

public static final Creator<CallAudioState> CREATOR

Responsible for creating AudioState objects for deserialized Parcels.

Public constructors

CallAudioState

Public methods

describeContents

Parameters
`route`	`int`: to convert into a string.

Returns
`String`	String representation of the provided audio route.

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.

equals

Added in API level 23

public boolean equals (Object obj)

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
`obj`	`Object`: the reference object with which to compare.

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