Question

我已经实现了库react-native-audio-recorder-player，并且能够记录音频。但是，每当我尝试从录制的路径播放音频时，都会收到错误消息。我在做什么错，我该如何解决？这似乎是一个相当普通的库，但是没有太多可用信息。另外，我已经要求并被授予所有权限来记录音频和对外部存储设备进行读取/写入。这是我的代码，它记录音频然后分别播放音频，这些功能是在按自定义按钮时触发的。

onStartRecord = async () => {
const path = Platform.select({
  ios: 'hello.m4a',
  android: 'sdcard/hello.mp4',
});
console.log(path);
//Result is the URL of the file
const result = await audioRecorderPlayer.startRecorder(path);
audioRecorderPlayer.addRecordBackListener((e) => {
  console.log(e);
  this.setState({
    recordSecs: e.current_position,
    recordTime: audioRecorderPlayer.mmssss(Math.floor(e.current_position)),
  });
  return;
});
console.log(`Result: ${result}`);
};

onStartPlay = async () => {
console.log('onStartPlay');
const path = Platform.select({
  ios: 'hello.m4a',
  android: 'sdcard/hello.mp4',
});
console.log(path);
const msg = await this.audioRecorderPlayer.startPlayer(path);
console.log(msg);
this.audioRecorderPlayer.addPlayBackListener((e) => {
  if (e.current_position === e.duration) {
    console.log('finished');
    this.audioRecorderPlayer.stopPlayer();
  }
  this.setState({
    currentPositionSec: e.current_position,
    currentDurationSec: e.duration,
    playTime: this.audioRecorderPlayer.mmssss(
      Math.floor(e.current_position),
    ),
    duration: this.audioRecorderPlayer.mmssss(Math.floor(e.duration)),
  });
  return;
});
};

运行音频onStartPlay（）之后，这是我收到的错误：
