void addOnRoutingChangedListener (AudioRouting.OnRoutingChangedListener listener, Handler handler)
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.
|
AudioDeviceInfo getPreferredDevice ()
Returns the selected output/input specified by setPreferredDevice(AudioDeviceInfo). Note that this
is not guaranteed to correspond to the actual device being used for playback/recording.
| Returns | |
|---|---|
AudioDeviceInfo |
|
AudioDeviceInfo getRoutedDevice ()
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.
| Returns | |
|---|---|
AudioDeviceInfo |
|
void removeOnRoutingChangedListener (AudioRouting.OnRoutingChangedListener listener)
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.
|
boolean setPreferredDevice (AudioDeviceInfo deviceInfo)
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. |
| Returns | |
|---|---|
boolean |
true if succesful, false if the specified AudioDeviceInfo is non-null and
does not correspond to a valid audio device.
