**首先安装cordovaNativeAudio和cordovaFileTransfer插件**

```
cordova plugin add cordova-plugin-media
cordova plugin add cordova-plugin-file
cordova plugin add cordova-plugin-file-transfer
```

**配置config.xml**

```
<preference name="AndroidPersistentFileLocation" value="Compatibility"/>
```

**js代码如下**

```
.controller('AudioInterNetCtrl', function ($scope, $cordovaMedia, $cordovaFileTransfer,$ionicPlatform,$cordovaFile,$timeout) {
$scope.params={url:''};
    $scope.play = function () {
      var fileName=new Date().getTime();
      document.addEventListener('deviceready', function () {

var url = $scope.params.url;

var targetPath = cordova.file.cacheDirectory + fileName+".mp3";
        var trustHosts = true;
        var options = {};

$cordovaFileTransfer.download(url, targetPath, options, trustHosts)
          .then(function(result) {
            // Success
            var media = $cordovaMedia.newMedia(targetPath);
            media.play();
          }, function(err) {
            // Error
          }, function (progress) {
            $timeout(function () {
              $scope.downloadProgress = (progress.loaded / progress.total) * 100;
            });
          });
      }, false);
    };
  })
```
**html代码如下**

```
<ion-view view-title="audioInterNet">
  <ion-content>
<textarea ng-model="params.url" style="width: 100%;height: 50%">
