public interface AudioRecordingMonitor

android.media.AudioRecordingMonitor

Known indirect subclasses

AudioRecord	The AudioRecord class manages the audio resources for Java applications to record audio from the audio input hardware of the platform.
MediaRecorder	Used to record audio and video.

AudioRecordingMonitor defines an interface implemented by AudioRecord and MediaRecorder allowing applications to install a callback and be notified of changes in the capture path while recoding is active.

Summary

Public methods
`abstract AudioRecordingConfiguration`	`getActiveRecordingConfiguration()` Returns the current active audio recording for this audio recorder.
`abstract void`	`registerAudioRecordingCallback(Executor executor, AudioManager.AudioRecordingCallback cb)` Register a callback to be notified of audio capture changes via a `AudioManager.AudioRecordingCallback`.
`abstract void`	`unregisterAudioRecordingCallback(AudioManager.AudioRecordingCallback cb)` Unregister an audio recording callback previously registered with `registerAudioRecordingCallback(java.util.concurrent.Executor, android.media.AudioManager.AudioRecordingCallback)`.

Public methods

getActiveRecordingConfiguration

Added in API level 29

public abstract AudioRecordingConfiguration getActiveRecordingConfiguration ()

registerAudioRecordingCallback

Added in API level 29

public abstract void registerAudioRecordingCallback (Executor executor, 
                AudioManager.AudioRecordingCallback cb)

Register a callback to be notified of audio capture changes via a AudioManager.AudioRecordingCallback. A callback is received when the capture path configuration changes (pre-processing, format, sampling rate...) or capture is silenced/unsilenced by the system.

Parameters
`executor`	`Executor`: `Executor` to handle the callbacks. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`cb`	`AudioManager.AudioRecordingCallback`: non-null callback to register

unregisterAudioRecordingCallback

Added in API level 29

public abstract void unregisterAudioRecordingCallback (AudioManager.AudioRecordingCallback cb)

Unregister an audio recording callback previously registered with registerAudioRecordingCallback(java.util.concurrent.Executor, android.media.AudioManager.AudioRecordingCallback).

Parameters
`cb`	`AudioManager.AudioRecordingCallback`: non-null callback to unregister
