【问题描述】：

我在 Ionic 2 应用程序中使用 cordova-plugin-media-with-compression。

在 ios 上，如果我传递 startRecord() 一个文件名并再次调用它而不更改 this.media，我可以录制和播放。

我似乎无法播放存储在文件系统中其他地方的音频文件 - 因为我必须将一个新的 src 传递给 startRecord()，这是我认为我做错了的一点。

import  Component  from '@angular/core';
import  ModalController, LoadingController, ToastController, Platform  from 'ionic-angular';
import  File, FileEntry, Entry, FileError, DirectoryEntry from 'ionic-native';

declare var Media: any; // stops errors w/ cordova-plugin-media-with-compression types

@Component(
  selector: 'page-add-doc',
  templateUrl: 'add-doc.html'
)
export class AddDocPage 
  isRecording = false;
  isRecorded = false;
  audioUrl ='';
  localAudioUrl = '';
  media: any;
  newFileName: string;
  newFileNameM4A: string;
  homerAudio = 'http://techslides.com/demos/samples/sample.m4a'

  constructor(private modalCtrl: ModalController,
              private loadingCtrl: LoadingController,
              private toastCtrl: ToastController,
              private platform: Platform,
            ) 
              platform.ready()
                .then(() => 
                  console.log('Platform Ready');
                );
              

  ionViewDidLoad() 
      this.newFileName = new Date().getTime().toString();
      this.newFileNameM4A = this.newFileName +'.m4a';
  

  onRecordAudio() 
    this.media = new Media(this.newFileNameM4A);
    this.media.startRecord();
    this.isRecording = true;
  
  onStopRecordAudio() 
    this.media.stopRecord();
    this.media.release();
    this.isRecording = false;
    this.isRecorded = true;
    try 
      File.copyFile(File.tempDirectory, this.newFileNameM4A, File.dataDirectory, this.newFileNameM4A)
        .then(
            (data: Entry) => 
              this.audioUrl = data.nativeURL;
        );
     catch (FileError) 
      console.log(FileError)
    ;
  

  onPlayback() 
    this.media = new Media(this.newFileNameM4A);
    this.media.play();
    this.media.release();
  
  onPlaybackTempDirectory() 
    this.media = new Media(File.tempDirectory + this.newFileNameM4A);
    this.media.play();
    this.media.release();
  

  onPlaybackDataDirectory() 
    this.media = new Media(File.dataDirectory + this.localAudioUrl);
    this.media.play();
    this.media.release();
      

  onHomerAudio() 
    this.media = new Media(this.homerAudio)
    this.media.play();
    this.media.release();

相信我可能已经用https://issues.apache.org/jira/browse/CB-7007的答案解决了这个问题

我不能在安卓设备上运行onHomerAudio() 方法？你能告诉我怎么做吗？
