Public methods
addOnRoutingChangedListener
abstract fun addOnRoutingChangedListener(
listener: AudioRouting.OnRoutingChangedListener!,
handler: Handler!
): Unit
Adds an AudioRouting.OnRoutingChangedListener
to receive notifications of routing changes on this AudioTrack/AudioRecord.
Parameters | |
---|---|
listener |
AudioRouting.OnRoutingChangedListener!: The AudioRouting.OnRoutingChangedListener interface to receive notifications of rerouting events. |
handler |
Handler!: Specifies the Handler object for the thread on which to execute the callback. If null , the Handler associated with the main Looper will be used. |
getPreferredDevice
abstract fun getPreferredDevice(): AudioDeviceInfo!
Returns the selected output/input specified by setPreferredDevice
. Note that this is not guaranteed to correspond to the actual device being used for playback/recording.
getRoutedDevice
abstract fun getRoutedDevice(): AudioDeviceInfo!
Returns an AudioDeviceInfo
identifying the current routing of this AudioTrack/AudioRecord. Note: The query is only valid if the AudioTrack/AudioRecord is currently playing. If it is not, getRoutedDevice()
will return null.
removeOnRoutingChangedListener
abstract fun removeOnRoutingChangedListener(listener: AudioRouting.OnRoutingChangedListener!): Unit
Removes an AudioRouting.OnRoutingChangedListener
which has been previously added to receive rerouting notifications.
Parameters | |
---|---|
listener |
AudioRouting.OnRoutingChangedListener!: The previously added AudioRouting.OnRoutingChangedListener interface to remove. |
setPreferredDevice
abstract fun setPreferredDevice(deviceInfo: AudioDeviceInfo!): Boolean
Specifies an audio device (via an AudioDeviceInfo
object) to route the output/input to/from.
Parameters | |
---|---|
deviceInfo |
AudioDeviceInfo!: The AudioDeviceInfo specifying the audio sink or source. If deviceInfo is null, default routing is restored. |
Return | |
---|---|
Boolean |
true if succesful, false if the specified AudioDeviceInfo is non-null and does not correspond to a valid audio device. |
