模拟器正常运行，真机调试无数据，请教？

代码如下，获取本地计算机上图片;
(Ip为192.168.1.3，模拟器中为10.0.2.2)public class MainActivity extends Activity {  
      
    private ScrollView scrollview01; 
    private TextView content; 
    private ImageView img;  
    private getBitmap getbitmap;
    private getBitmap bitmap1;
    private Button btn;
  
    /** Called when the activity is first created. */  
    @Override  
  public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main); 
  img=(ImageView)findViewById(R.id.img); 
     btn=(Button)findViewById(R.id.btnlogin);  
        btn.setOnClickListener(new OnClickListener(){
       @Override
        public void onClick(View v)
  { 
         System.out.println("OK");           
            new Thread(new Runnable() {
                public void run() {
                       System.out.println("OK!!"); 
                        bitmap1= new getBitmap();
                       
                  String newurl = "http://192.168.1.3:56910/Web/upload/comm/2010-05-27/071b884b-f0b7-4937-ae6e-f37ec8273611.jpg";  
                        final Bitmap bitmap = bitmap1.getBitmap(newurl);//从网络获取图片                     
                        img.post(new Runnable(){
                        public void run(){
                        img.setImageBitmap(bitmap);}});}}).start();}});}}
模拟器中能获取图片，真机中无数据log：请教到底是啥问题啊。通过u口测试
