Cordova list all files from application directory (WWW)

问题

I am using Cordova 4.2.0 with plugins File and media. I have some mp3 files in audio folder inside www directory. I am able to play files through media plugin using path cordova.file.applicationDirectory+"www/audio/01.mp3" and trying to get all available files list using window.resolveLocalFileSystemURL but unable to do so. Please see below code always goes to fail function.

window.resolveLocalFileSystemURL(cordova.file.applicationDirectory+'/www/audio', 
    function(dirEntry){
        alert('in');
    }, 
    fail
);

Please guide me the best way.

You can use this function to get all available files in www/audio/ folder

function listDir(path){
  window.resolveLocalFileSystemURL(path,
    function (fileSystem) {
      var reader = fileSystem.createReader();
      reader.readEntries(
        function (entries) {
          console.log(entries);
        },
        function (err) {
          console.log(err);
        }
      );
    }, function (err) {
      console.log(err);
    }
  );
}
//example: list of www/audio/ folder in cordova/ionic app.
listDir(cordova.file.applicationDirectory + "www/audio/");
