设备上的 React-native android

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

2.

Configure your files according to the doc in each library

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:

4.

Create assets folder and add song_sound.m4a like this :

通过 USB 连接您的安卓设备

//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

Behavior

Works perfectly : the sound is loaded and is played

cd android 
./gradlew assembleRelease
./gradlew installRelease

行为

声音没有加载，显示的错误是:

Behavior

The sound doesn't load and the error displayed is :

{
    "nativeStackAndroid":[],
    "userInfo":null,
    "message":"com.google.android.exoplayer2.upstream.FileDataSource$FileDataSourceException: java.io.FileNotFoundException: assets_song_sound: open fialed: ENOENT (No such file or directory)",
    "code":"E_LOAD_ERROR",
    "line": 18,
    "column": 1111,
    "sourceURL":"index.android.bundle"
}

我想要什么?

只需像在调试中一样在发行版中加载和播放音频.

推荐答案

终于找到答案了.

require()

在发布时效果不佳.

我不知道为什么 require() 在与 Image 一起发布时效果很好，但在 Audio

I don't know why require() works well in release with Image but not with Audio

所以你需要使用

{ uri: 'asset:/my_sound.m4a' }

并将您的声音文件(如 my_sound.m4a)放入 android/app/src/main/assets:

and put your sound file (like my_sound.m4a) in android/app/src/main/assets:

它会起作用的.
