音振协同，表示在播放声音时，可同步发起振动。可用于来电通知、消息提醒等场景
导入模块
import { audioHaptic } from '@kit.AudioKit';audioHaptic.getAudioHapticManagergetAudioHapticManager():AudioHapticManager获取音振管理器。系统能力： SystemCapability.Multimedia.AudioHaptic.Core
let audioHapticManagerInstance: audioHaptic.AudioHapticManager = audioHaptic.getAudioHapticManager();AudioHapticManager管理音振协同功能。
在调用AudioHapticManager的接口前registerSourceregisterSource(audioUri: string, hapticUri: string): Promise注册音频和振动资源的Uri，使用Promise方式异步返回结果。
import { BusinessError } from '@kit.BasicServicesKit';
let audioUri = 'data/audioTest.wav'; // 需更改为目标音频资源的Urilet hapticUri = 'data/hapticTest.json'; // 需更改为目标振动资源的Urilet 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}`);});以上摘抄官网部分使用说明
官网 demo 代码如下：
import { BusinessError } from '@kit.BasicServicesKit';
let audioUri = 'data/audioTest.wav'; // 需更改为目标音频资源的Urilet hapticUri = 'data/hapticTest.json'; // 需更改为目标振动资源的Urilet 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}`);});
let options: audioHaptic.AudioHapticPlayerOptions = {muteAudio: false, muteHaptics: false};let audioHapticPlayerInstance: audioHaptic.AudioHapticPlayer | undefined = undefined;
audioHapticManagerInstance.createPlayer(id, options).then((value: audioHaptic.AudioHapticPlayer) => { audioHapticPlayerInstance = value; console.info(`Create the audio haptic player successfully.`);}).catch ((err: BusinessError) => { console.error(`Failed to create the audio haptic player. ${err}`);});看上去也没有啥困难的。事实上也的确不难
坑位
但坑就出在那个文件路径上’data/audioTest.wav’；这个是 string 类型的路径而项目一般都会把文件放到 rawfile 资源目录里，然后问题来了，怎么获取到 rawfile 里文件的路径地址了，我找了半天也没有找到，然后找了几个同事也没有发现。结果是花了两天也没有找到好的办法
突破点：
registerSource需要的是 string 类型的路径地址；那给它一个路径文件地址就可以了。于是开始了骚操作如下：
1、使用沙箱定义路径地址：
let audioUriPath = getContext().cacheDir + '/audioTest.mp3';let hapticUriPath = getContext().cacheDir + '/hapticTest.json';这样就有了地址了
2、使用resourceManager 调用getRawFileContentSync读取内容
let audioUriConte = getContext().resourceManager.getRawFileContentSync('audioTest.mp3');let hapticUriConte = getContext().resourceManager.getRawFileContentSync('hapticTest.json');3、然后使用文件写入到定义的文件路径地址里
FileUtils.writeFileOnlyOne(audioUriPath, audioUriConte);FileUtils.writeFileOnlyOne(hapticUriPath, hapticUriConte);附一份
FileUlteimport { fileIo as fs } from '@kit.CoreFileKit';
const TAG='[FileUtils]'
export namespace FileUtils{
export function writeFileOnlyOne(filePath: string, content: Uint8Array) {
try {
let res=fs.accessSync(filePath)
if(res){
console.debug(TAG,'已存在 audioUriPath='+filePath)
return }
} catch (e) {
console.debug(TAG,JSON.stringify(e))
}
console.debug(TAG,'writeFile called!-start writing')
writeFile(filePath,content) }
export function writeFile(filePath: string, content: Uint8Array){
const file: fs.File = fs.openSync(filePath , fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
fs.writeSync(file.fd, content.buffer);
fs.closeSync(file);
}
}其他就回到官方使用说明里走逻辑流程即可===================END
