react-native-audio

本项目基于 react-native-audio@4.2.2 开发。

该第三方库的仓库已迁移至 Gitee,且支持直接从 npm 下载,新的包名为:@react-native-ohos/react-native-audio,具体版本所属关系如下:

Version Package Name Repository Release
<= 4.2.2@deprecated @react-native-oh-library/react-native-audio Github(deprecated) Github Releases(deprecated)
> 4.2.2 @react-native-ohos/react-native-audio Gitee Gitee Releases

安装与使用

进入到工程目录并输入以下命令:

npm

npm install @react-native-ohos/react-native-audio

yarn

yarn add @react-native-ohos/react-native-audio

下面的代码展示了这个库的基本使用场景:

        await AudioRecorder.requestAuthorization()

        // you check premission any time
        await AudioRecorder.checkAuthorizationStatus();

        // Initialize recording parameters

2. Manual Link

此步骤为手动配置原生依赖项的指导。

首先需要使用 DevEco Studio 打开项目里的 HarmonyOS 工程 harmony

2.1 Overrides RN SDK

为了让工程依赖同一个版本的 RN SDK,需要在工程根目录的 harmony/oh-package.json5 添加 overrides 字段,指向工程需要使用的 RN SDK 版本。替换的版本既可以是一个具体的版本号,也可以是一个模糊版本,还可以是本地存在的 HAR 包或源码目录。

关于该字段的作用请阅读官方说明

{
  "overrides": {
    "@rnoh/react-native-openharmony": "^0.72.38" // ohpm 在线版本
    // "@rnoh/react-native-openharmony" : "./react_native_openharmony.har" // 指向本地 har 包的路径
    // "@rnoh/react-native-openharmony" : "./react_native_openharmony" // 指向源码路径
  }
}

2.2 引入原生端代码

目前有两种方法:

  1. 通过 har 包引入(在 IDE 完善相关功能后该方法会被遗弃,目前首选此方法);
  2. 直接链接源码。

方法一:通过 har 包引入

[!TIP] har 包位于三方库安装路径的 harmony 文件夹下。

打开 entry/oh-package.json5,添加以下依赖

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-ohos/react-native-audio": "file:../../node_modules/@react-native-ohos/react-native-audio/harmony/audio.har"
  }

点击右上角的 sync 按钮

或者在终端执行:

cd entry
ohpm install

方法二:直接链接源码

[!TIP] 如需使用直接链接源码,请参考直接链接源码说明

2.3 配置 CMakeLists 和引入 AudioPackage

[!TIP] 版本 4.2.3 及以上需要.

打开 entry/src/main/cpp/CMakeLists.txt,添加:

+ set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")

# RNOH_BEGIN: manual_package_linking_1
+ add_subdirectory("${OH_MODULES}/@react-native-ohos/react-native-audio/src/main/cpp" ./audio)
# RNOH_END: manual_package_linking_1

# RNOH_BEGIN: manual_package_linking_2
+ target_link_libraries(rnoh_app PUBLIC rnoh_audio)
# RNOH_END: manual_package_linking_2

打开 entry/src/main/cpp/PackageProvider.cpp,添加:

#include "RNOH/PackageProvider.h"
#include "generated/RNOHGeneratedPackage.h"
+ #include "AudioPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
      std::make_shared<RNOHGeneratedPackage>(ctx),
+     std::make_shared<AudioPackage>(ctx)
    };
}

打开 entry/src/main/ets/RNPackagesFactory.ts,添加:

  ...
+ import {AudioPackage} from '@react-native-ohos/react-native-audio/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new AudioPackage(ctx)
  ];
}

2.4 运行

点击右上角的 sync 按钮

或者在终端执行:

cd entry
ohpm install

然后编译、运行即可。

3. 约束与限制

3.1 兼容性

请到三方库相应的 Releases 发布地址查看 Release 配套的版本信息:@react-native-ohos/react-native-audio Releases

4. API

[!TIP] "Platform"列表示该属性在原三方库上支持的平台。

[!TIP] "HarmonyOS Support"列为 yes 表示 HarmonyOS 平台支持该属性;no 则表示不支持;partially 表示部分支持。使用方法跨平台一致,效果对标 iOS 或 Android 的效果。

Name Description Type Required Platform HarmonyOS Support
requestAuthorization Request microphone permission function no Android/IOS yes
checkAuthorizationStatus Check authorization status function no Android/IOS yes
prepareRecordingAtPath Initialize recording instance parameters function no Android/IOS yes
startRecording start recording function no Android/IOS yes
pauseRecording Pause recording function no Android/IOS yes
resumeRecording Resume recording function no Android/IOS yes
stopRecording stop recording function no Android/IOS yes

5. 遗留问题

6. 其他

6.1 不同系统支持的编码格式

Encodings supported on iOS: lpcm, ima4, aac, MAC3, MAC6, ulaw, alaw, mp1, mp2, alac, amr.

Encodings supported on Android: aac, aac_eld, amr_nb, amr_wb, he_aac, vorbis.

Encodings supported on Harmony: aac.

AudioQuality、MeteringEnabled、MeasurementMode is only for ios now.
