我的应用程序打开登录页面，但当我尝试连接到服务器时，手机上没有任何反应。但它适用于模拟器

Question

public void onClick(View v) {
        if(v==btLogin)
        {   
            TelephonyManager mngr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

                imeino=Long.valueOf(mngr.getDeviceId());
            }catch(NumberFormatException ne){
                errormessage=new StringBuilder("Invalid ");
                errormessage.append("Failed to parse id " + ne.getMessage());
            }
            if(etMobileNo.getText().toString().trim().startsWith("0") | etMobileNo.getText().toString().trim().length()<10 | etMobileNo.getText().toString().trim().equals("")| etPassword.getText().toString().trim().equals("")){
                Toast.makeText(getBaseContext(),"Mobile No. & Password fields required",Toast.LENGTH_LONG).show();
            }else{  
                System.out.println("Hello");
                try{
                    result=objCommonServices.authenticate(etMobileNo.getText().toString().trim(),etPassword.getText().toString().trim(),mngr.getDeviceId().toString()); 
                    System.out.println(result);   
                    if(result.contains("Err-"))
                    {
                        System.out.println(result);
                        Toast.makeText(this,result,Toast.LENGTH_LONG).show();
                    }else{

                        showDialog(0);
                        t = new Thread() {
                            public void run() {
                                register();
                                try {
                                    Thread.sleep(500);
                                    removeDialog(0);
                                    //   I want to show the dialog box like registered successfully after removing this dialog//
                                } catch (InterruptedException e) {
                                    e.printStackTrace();
                                }
                            }
                        };
                        t.start();           
                    }


                }catch(Exception ne){}
            }}


void register()
    {
        try{
            String[] split1= result.split(":");
            uID= Integer.valueOf(split1[0]);
            objCommonBean.setuId(uID);
            objCommonBean.setPassword(password);
            objCommonBean.setMobileNo(mobileNo);
            objCommonBean.setDeviceId(imeino);
            Bundle b=new Bundle();
            b.putSerializable("objCommonBean",objCommonBean);   
            this.finish();
            startActivity(new Intent(this,HomeActivity.class).putExtras(b));
        }catch(Exception e){


}    // My Login Page


    }

//我的服务页面包含以下

public String authenticate(String mobileNo, String password, String deviceId) {
        CommonBean objCommonBean=null;
        String result=null;
        //StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        //StrictMode.setThreadPolicy(policy);
        DefaultHttpClient client=new DefaultHttpClient();

HttpPost request =new HttpPost("http://wsezypoint.ezypoint.org/eauthuzer.aspx");
        List<NameValuePair> param=new ArrayList<NameValuePair>();
                param.add(new BasicNameValuePair("mobileNo",mobileNo));
                param.add(new BasicNameValuePair("password",password));
                param.add(new BasicNameValuePair("imei_no",deviceId));
                UrlEncodedFormEntity entity=new UrlEncodedFormEntity(param);
                request.setEntity(entity);
                HttpResponse response = client.execute(request);
                InputSource in = new InputSource(response.getEntity().getContent());
                InputStream isr=in.getByteStream();
               result= readData(isr);
}

我无法从手机登录，但我可以从模拟器登录。是否需要在服务中实施严格的策略或者在apk文件中存在问题，即。生成的文件是错误的
