<script>
      var soundChannel1;    // Used to stop the MP3 sound.
      var button1;        // Used to reference the DOM button object with the ID "button1"

      function init(){
         if(window.runtime){
            console.err("runtime is ok")
         }
         var urlReq = new window.runtime.flash.net.URLRequest("test.mp3");
         sampleMp3 = new window.runtime.flash.media.Sound();
         sampleMp3.load(urlReq);
         sampleMp3.addEventListener(air.Event.COMPLETE, loaded);
      }
    
   </script>

一段javascripy想使用AIR提供flash接口播放文件，但捕获到了
Uncaught TypeError: Cannot read property 'flash' of undefined

本人菜鸟新手。实在是费解，帮忙看看 是怎么回事
