播放聲音，我想從網址:: 播放聲音，但我不能能夠做到這一點，我有實現這個代碼

package com.TestAudio; 


import android.app.Activity; 
import android.media.AudioManager; 
import android.media.MediaPlayer; 
import android.os.Bundle; 

public class TestAudio extends Activity { 
    /** Called when the activity is first created. */ 
    private MediaPlayer xmPlayer2, xmPlayer3, xmPlayer4, xmPlayer5, xmPlayer6, 
    xmPlayer7,xmPlayer8,xmPlayer9,xmPlayer10,xmPlayer11; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 




     prepareforaudio(xmPlayer2,"bike_route.mp3"); 
     prepareforaudio(xmPlayer3,"closed.mp3"); 
     prepareforaudio(xmPlayer4,"exit.mp3"); 
     prepareforaudio(xmPlayer5,"no_parking.mp3"); 
     prepareforaudio(xmPlayer6,"one_way.mp3"); 
     prepareforaudio(xmPlayer7,"phone.mp3"); 
     prepareforaudio(xmPlayer8,"rail_road_crossing.mp3"); 
     prepareforaudio(xmPlayer9,"sale.mp3"); 
     prepareforaudio(xmPlayer10,"stop.mp3"); 
     prepareforaudio(xmPlayer11,"turn_off_tap.mp3"); 



    } 
    public void prepareforaudio(MediaPlayer player,String music1) 
    { 
     try 
     { 
     player.setAudioStreamType(AudioManager.STREAM_MUSIC); 
     player.setDataSource("http://xyz/MRESC/images/test/"+music1); 
     player.prepare(); 
     player.start(); 
     }catch (Exception e) { 
      // TODO: handle exception 
     } 
    } 
}
