localhost在android studio中拒绝了(localhost refused in android studio)

 我正在使用wampserver并尝试使用php脚本通过json解析从服务器获取记录。 我想在我的Android应用程序上显示该数据.... 
 
 我的脚本代码很清楚，它工作得很完美。而且我也很清楚android代码。 但是，当我运行我的应用程序时，数据不会显示在我的应用程序上.... 
 
 这是我的android代码....

    getData();

public void getData(){

    InputStream isr = null;
    try{
        HttpClient httpclient = new DefaultHttpClient();

        HttpPost httppost = new HttpPost("http://10.0.2.2/getAllCustomers.php");
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        isr = entity.getContent();
}
catch(Exception e){
        Log.e("log_tag", "Error in http connection "+e.toString());
        resultView.setText("Couldnt connect to database");
}
//convert response to string
try{
        BufferedReader reader = new BufferedReader(new InputStreamReader(isr,"iso-8859-1"),8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
        }
        isr.close();

        result=sb.toString();
}
catch(Exception e){
        Log.e("log_tag", "Error  converting result "+e.toString());
}

//parse json data
       try {
       String s = "";
       JSONArray jArray = new JSONArray(result);

   for(int i=0; i<jArray.length();i++){
       JSONObject json = jArray.getJSONObject(i);
       s = s + 
               "Name : "+json.getString("FirstName")+" "+json.getString("LastName")+"\n"+
               "Qualification : "+json.getInt("Qualification")+"\n"+
               "Mobile Using : "+json.getString("Mobile")+"\n\n";
       }

      resultView.setText(s);

   } catch (Exception e) {
// TODO: handle exception
   Log.e("log_tag", "Error Parsing Data "+e.toString());
   }

    }

  }
 
 以下是我面临的错误........... 
 
Error Parsing Data org.json.JSONException: Value <br of type    java.lang.String cannot be converted to JSONArray
 
 以下是我的PHP脚本........... 
 
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
      die('Could not connect: ' . mysql_error()); 

}
 mysql_select_db("testDatabase", $con);
 $result = mysql_query("SELECT * FROM Customer");
 while($row = mysql_fetch_assoc($result))
 {
       $output[]=$row;
 }
 print(json_encode($output));
 mysql_close($con);

?>
 
 我不明白为什么我没有得到任何记录....如果有人围绕这个，那么请帮助这个.....
