angularjs - Cordova Media 插件不起作用

Question

每个人！我已经使用 cordova-plugin-media 成功创建了媒体列表，但是当我触发录制时，我得到了错误；

{message: "Failed to start recording using AVAudioRecorder", code: 1}

我什至无法想象会发生什么以及为什么会发生此错误（（（

这是我的 JS 代码

(function() {
 "use strict";
  angular.module('app.services')
  .factory('soundService', function($q) {
    var fileDirectory = null,
        mediasForPlay = [],
        currentMedia = null;

    return {
      createDir: function(segments) {

//get dir

        window.resolveLocalFileSystemURL(cordova.file.cacheDirectory, function (dir) { // create All segments for video at once
          fileDirectory = dir;
          segments = segments.map(function (elem) {

//here we create files for recording

            return $q(function(resolve, reject) {
              fileDirectory.getFile(elem.id + '.wav', {create: true, exclusive: false},
                  function (file) {resolve(file)},
                  function(err) {reject(err)});
            });
          });
          $q.all(segments).then(function(data) {  

//transform it to media 

            mediasForPlay = data.map(function(elem) {
              var url = elem.nativeURL.replace('file://', ''),
              media = new Media(url, function() {console.log('success'); media.release()}, function (err) {console.log(err)});
              return media;
            });
          });
        })
      },
      startRecord: function(segmentId, index) {
        currentMedia = mediasForPlay[index];

//here we get an error   

        currentMedia.startRecord();
      }
    }
  })
    })();
