环境

Expo CLI 3.11.1 环境信息：系统：操作系统：Windows 10 二进制文件：纱线：1.22.4 - C:\Users\user\AppData\Roaming\npm\yarn.CMD npm: 6.12.0 - C:\Program Files\nodejs\npm.CMD IDE： android Studio：版本 3.6.0.0 AI-192.7142.36.36.6308749

设备上的 React-native android

复制步骤：

1.

npx react-native init ReactRelease --version 0.62.2
npm install react-native-unimodules@0.9.0 --save 
expo install expo-av

2.

根据每个库中的文档配置文件

3.

编辑 App.js

import React,  Component  from 'react';
import  Text, StyleSheet, View, Button, Alert  from 'react-native';
import  Audio  from 'expo-av';
import * as Permissions from 'expo-permissions';

var audioObjectActions = new Audio.Sound();

export default class App extends Component 
    constructor(props) 
        super(props);

        this.state = ;
    

    async componentDidMount() 
        await Permissions.askAsync(Permissions.AUDIO_RECORDING);
        await Audio.setAudioModeAsync(
            staysActiveInBackground: true,
            allowsRecordingios: false,
            interruptionModeIOS: Audio.INTERRUPTION_MODE_IOS_DUCK_OTHERS,
            playsInSilentModeIOS: true,
            playThroughEarpieceAndroid: false,
            interruptionModeAndroid: Audio.INTERRUPTION_MODE_ANDROID_DUCK_OTHERS,
            shouldDuckAndroid: true
        );
    

    async _playRandomAction() 
        try 
            audioObjectActions.setOnPlaybackStatusUpdate(this._onPlaybackStatusUpdateAction);
            await audioObjectActions.loadAsync(require('./assets/song_sound.m4a'));
            await audioObjectActions.playAsync();
         catch (error) 
            Alert.alert('ERROR : ', '' + JSON.stringify(error));
        
    

    _onPlaybackStatusUpdateAction = async (playbackStatus) => 
        if (!playbackStatus.isLoaded) 
            // Update your UI for the unloaded state
            if (playbackStatus.error) 
                console.log(`Encountered a fatal error during playback: $playbackStatus.error`);
                // Send Expo team the error on Slack or the forums so we can help you debug!
            
         else 
            if (playbackStatus.didJustFinish && !playbackStatus.isLooping) 
                await audioObjectActions.stopAsync();
                await audioObjectActions.unloadAsync();
            
        
    ;

    render() 
        return (
            <View style=styles.container>
                <Text> Test Audio </Text>
                <Button title="On joue le morceau" onPress=async () => this._playRandomAction() />
            </View>
        );
    


const styles = StyleSheet.create(
    container: 
        flex: 1,
        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: '#555555'
    
);

4.

创建 assets 文件夹并像这样添加 song_sound.m4a：

5

通过 USB 连接您的安卓设备

在调试中测试：

//POWERSHELL 1
npx react-native run-android   

//POWERSHELL 2
npm start

行为

完美运行：声音已加载并播放

在发布中测试

cd android 
./gradlew assembleRelease
./gradlew installRelease

行为

声音没有加载，显示的错误是：

    "userInfo":null,
    "message":"com.google.android.exoplayer2.upstream.FileDataSource$FileDataSourceException: java.io.FileNotFoundException: assets_song_sound: open fialed: ENOENT (No such file or directory)",
