java try catch必须成对使用，否则报错

     try{
        Uri file = Uri.parse("hettp:://wwww.perlgurl.org/podcast/archives "
        + "/podcasts/PerlgurlPromo.mp3");
        mp = MediaPlayer.create(this, file);
        mp.start();
    }
    catch (Exception e) {
    Log.e(DEBUG_TAG, "Player failed", e);

    }
