使用AudioHaptic开发音振协同播放功能

AudioHaptic¹¹⁺提供音频与振动协同播放及管理的方法，适用于需要在播放音频时同步发起振动的场景，如来电铃声随振、键盘按键反馈、消息通知反馈等。

开发指导

使用AudioHaptic播放音频并同步开启振动，涉及到音频及振动资源的管理、音频时延模式及音频流使用类型的配置、音振播放器的创建及管理等。本开发指导将以一次音振协同播放的过程为例，向开发者讲解如何使用AudioHaptic进行音振协同播放，建议配合AudioHaptic的API说明阅读。

权限申请

如果应用创建的AudioHapticPlayer需要触发振动，则需要校验应用是否拥有该权限：ohos.permission.VIBRATE。

声明权限。
向用户申请授权。

开发步骤及注意事项

获取音振管理器实例，并注册音频及振动资源，资源支持情况可以查看AudioHapticManager。

import audio from '@ohos.multimedia.audio';
import audioHaptic from '@ohos.multimedia.audioHaptic';
import { BusinessError } from '@ohos.base';

let audioHapticManagerInstance: audioHaptic.AudioHapticManager = audioHaptic.getAudioHapticManager();

let audioUri = 'data/audioTest.wav'; // 需更改为目标音频资源的Uri
let hapticUri = 'data/hapticTest.json'; // 需更改为目标振动资源的Uri
let id = 0;

audioHapticManagerInstance.registerSource(audioUri, hapticUri).then((value: number) => {
  console.info(`Promise returned to indicate that the source id of the registerd source ${value}.`);
  id = value;
}).catch ((err: BusinessError) => {
  console.error(`Failed to register source ${err}`);
});

设置音振播放器参数，各参数作用可以查看AudioHapticManager。

let latencyMode: audioHaptic.AudioLatencyMode = audioHaptic.AudioLatencyMode.AUDIO_LATENCY_MODE_FAST;
audioHapticManagerInstance.setAudioLatencyMode(id, latencyMode);

let usage: audio.StreamUsage = audio.StreamUsage.STREAM_USAGE_NOTIFICATION;
audioHapticManagerInstance.setStreamUsage(id, usage);

创建AudioHapticPlayer实例。

let options: audioHaptic.AudioHapticPlayerOptions = {muteAudio: false, muteHaptics: false};
let audioHapticPlayer: audioHaptic.AudioHapticPlayer | undefined = undefined;

audioHapticManagerInstance.createPlayer(id, options).then((value: audioHaptic.AudioHapticPlayer) => {
  console.info(`Promise returned to indicate that the audio haptic player instance.`);
  audioHapticPlayer = value;
}).catch ((err: BusinessError) => {
  console.error(`Failed to create player ${err}`);
});
console.info(`Create the audio haptic player successfully.`);

调用start()方法，开启音频播放并同步开启振动。

audioHapticPlayer.start().then(() => {
  console.info(`Promise returned to indicate that start playing successfully.`);
}).catch ((err: BusinessError) => {
  console.error(`Failed to start playing. ${err}`);
});

调用stop()方法，停止音频播放并同步停止振动。

audioHapticPlayer.stop().then(() => {
  console.info(`Promise returned to indicate that stop playing successfully.`);
}).catch ((err: BusinessError) => {
  console.error(`Failed to stop playing. ${err}`);
});

释放AudioHapticPlayer实例。

audioHapticPlayer.release().then(() => {
  console.info(`Promise returned to indicate that release the audio haptic player successfully.`);
}).catch ((err: BusinessError) => {
  console.error(`Failed to release the audio haptic player. ${err}`);
});

将已注册的音频及振动资源移除注册

audioHapticManagerInstance.unregisterSource(id).then(() => {
  console.info(`Promise returned to indicate that unregister source successfully`);
}).catch ((err: BusinessError) => {
  console.error(`Failed to unregistere source ${err}`);
});
