反应本地图像和声音无法在真实设备上播放

Question

我有一个聊天屏幕，从中可以显示已发送/已接收的文本，图像和语音注释，在模拟器中一切正常，但在真实设备中显示文本，但是图像和语音注释气泡只是一个空白。

这是我的模拟器，但是在真实的设备上，我所看到的只是一个空白区域，其中应显示内容的高度和宽度。

这是我的chat.js文件

<Container loading={ this.state.loading }>

    <StatusBar barStyle="light-content" />

      <View style={ styles.messages_outer_container }>

        <View style={ styles.countdown_container }>

          <Text style={ styles.countdown }> { (this.state.appointment.status == 'completed') ? 'Appointment Completed' : this.state.session ? this.state.session : 'Waiting For Consultant Approval' } </Text>

          <View style={ styles.countdown_hr } />

        </View>

        <FlatList
          inverted
          ref={ (ref) => this.chat_list = ref }
          data={ this.state.on_load_message }
          keyExtractor={ item => item.id }
          renderItem={ ({ item }) => <ChatBubbles message={ item } from={ this.state.from } /> }
        />

      </View>

      <KeyboardAvoidingView behavior="padding">

        <ChatBottomContainer
          set_message={ (message) => this.setState({ message }) }
          send_message={ () => this.send_message(this.state.message, 'text') }
          message={ this.state.message }
          end_session={ this.state.end_session }
          send_attachment={ this.send_attachment }
          send_voice_note={ this.send_voice_note }
        />

      </KeyboardAvoidingView>

    </Container>

这是我的chat-bubbles.js

  constructor(props) {
    super(props);
    this.state = { timer: moment().minute(0).second(0), is_playing: false };
  }

  play_sound = (file_path) => {

let voice_note = new Sound(file_path, undefined, error => {

  if (error) {
    console.warn(error);
    return;
  }

  else {

    this.timer = setInterval(() => this.setState(prev => ({ timer: prev.timer.add(1, 'second') })), 1000)

    this.setState({ is_playing: true })

    voice_note.play(() => {

      voice_note.release()

      clearInterval(this.timer)

      this.setState({ timer: moment().minute(0).second(0) })

      this.setState({ is_playing: false })

    })

  }

    })

  }

  render () {

用于图像和声音的文件都位于计算机上，并且您使用localhost：1337 / ...来引用它们。 显然，这在物理设备上将不起作用，这些文件将需要添加到iOS和/或Android资源中，并且您需要使用require（''）

进行不同引用。

有关使用静态资源的更多信息，请参见in the official documentation。
