java.lang.Object

ohos.media.audio.AudioInterrupt

public class AudioInterrupt
extends Object

An audio interruption management mechanism used to resolve audio playback conflicts among multiple applications.

If you want to reduce the volume of background audio, set the AUDIO_STREAM_FLAG_MAY_DUCK flag in AudioStreamInfo. If you want to resume playing the background audio after the interruption ends, set the AUDIO_STREAM_FLAG_MAY_RESUME flag in AudioStreamInfo.
