Public constructors

CallAudioState

Added in API level 23
CallAudioState(
    muted: Boolean,
    route: Int,
    supportedRouteMask: Int)

Constructor for a CallAudioState object.

Parameters
muted Boolean: true if the call is muted, false otherwise.
route Int: The current audio route being used. Allowed values: ROUTE_EARPIECE ROUTE_BLUETOOTH ROUTE_WIRED_HEADSET ROUTE_SPEAKER Value is either 0 or a combination of android.telecom.CallAudioState#ROUTE_EARPIECE, android.telecom.CallAudioState#ROUTE_BLUETOOTH, android.telecom.CallAudioState#ROUTE_WIRED_HEADSET, and android.telecom.CallAudioState#ROUTE_SPEAKER
supportedRouteMask Int: Bit mask of all routes supported by this call.

Public methods

audioRouteToString

Added in API level 23
static fun audioRouteToString(route: Int): String!

Converts the provided audio route into a human readable string representation.

Parameters
route Int: to convert into a string.
Return
String! String representation of the provided audio route.

describeContents

Added in API level 23
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.

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

equals

Added in API level 23
fun equals(other: Any?): Boolean
Parameters
obj the reference object with which to compare.
Return
Boolean true if this object is the same as the obj argument; false otherwise.

getActiveBluetoothDevice

Added in API level 28
fun getActiveBluetoothDevice(): BluetoothDevice!
Return
BluetoothDevice! The BluetoothDevice through which audio is being routed. Will not be null if getRoute() returns ROUTE_BLUETOOTH.
