React-native-sound: null is not an object (evaluating 'RNSound.IsAndroid')

[FatemeKhodayari]

:beetle: Description

I tried installing and using this package for playing an audio file which I fetch from an API.

:beetle: What have you tried?

I followed the instructions in the wiki. I've installed the package using npm. I've also linked it using react-native link react-native-sound. It says that both Android and IOS modules have been linked. But then when I start the metro server and reload the app, everything crashes giving the error. I've also tried rebuilding the project but it doesn't work either.

:beetle: Please post your code:

import React, { Component } from 'react';
import { connect } from 'react-redux';
import { View } from 'react-native';
import { Card, Image, Button } from 'react-native-elements';
import Sound from 'react-native-sound';

class Activity extends Component {

  playSound() {
    const track = new Sound(this.props.sound, null, (error) => {
      if (error)
        console.log("Can't play sound. ", e);
      else
        track.play();
    });
  }

  render(){
    return (
      <Card title={this.props.title}>
        <View style={{ flexDirection: 'row', justifyContent: 'space-between', paddingTop: 20 }}>
          <Image
            source={{ uri: this.props.questions[0].options[0].value.image }}
            style={{ width: 100, height: 100 }}
          />
          <Image
            source={{ uri: this.props.questions[0].options[1].value.image }}
            style={{ width: 100, height: 100 }}
          />
          <Image
            source={{ uri: this.props.questions[0].options[2].value.image }}
            style={{ width: 100, height: 100 }}
          />
        </View>
        <View style={{ alignItems: 'center' }}>
          <Button
            titleStyle={{ fontSize: 40, fontWeight: '700', padding: 50 }} 
            title={this.props.presentation}
            onPress={this.playSound}
          />
        </View>
      </Card>
    );
  }
}

const mapStateToProps = (state) => {
  const { presentation, sound, title, questions } = state.game;
  return { presentation, sound, title, questions };
};

export default connect(mapStateToProps, {})(Activity);

Android works fine.

Look this: https://github.com/zmxv/react-native-sound/issues/215#issuecomment-510543679

Running pod install
Deleting ios/build
Running react-native run-ios

I think this may work for IOS. But my problem is with Android only. :)

As far as I tried, there's no need to do the react-native link react-native-sound step. React Native does it automatically. No need to follow the instructions to wiki. Just rebuild the app and reload it. Everything works fine.

Same to me in the Android 10.0 emulator.
react-native: 0.61.5
react-native-sound: 0.11.0

I have the same problem. Just installed react-native-sound and I'm getting this error in Android emulator. I've checked the linking (compared to manual steps) and everything looks in order.

[vaidis]

same here on linux / expo. The strange thinig is that the same problem occurs also with other libraries like react-native-track-player. Is it possible that react native is responsible for this fault?

[Cat107]

Same problem, not working on iOS expo app

[AdamGerthel]

@Cat107 Libraries which require linking will never work with an Expo app, unless you're using the bare workflow. See https://docs.expo.io/introduction/why-not-expo/

I'm facing exactly the same issue on an ios device, why is this closed what should i do?

@Cat107 I tried to replace with import {Audio} from 'expo-av'
