Android web service not parsing data from localhost

[aginueget]

I am trying to connect Android App to java webservice to get pHp parsed values.Php Script is :\[code\]<?php$data = http://stackoverflow.com/questions/15835125/array('name' => 'Froyo', 'version' => 'Android 2.2'); print (json_encode($data)); ?> \[/code\]And the Java WebService is : \[code\]package com.json.php;import android.app.Activity;import android.os.Bundle;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import android.widget.TextView;import org.apache.http.HttpResponse;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.HttpClient;import org.apache.http.client.methods.HttpPost;import org.apache.http.impl.client.DefaultHttpClient;import org.json.JSONException;import org.json.JSONObject;public class JSONExampleActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://127.0.0.1/test.php"); TextView textView = (TextView)findViewById(R.id.textView1); try { HttpResponse response = httpclient.execute(httppost); String jsonResult = inputStreamToString(response.getEntity().getContent()).toString(); JSONObject object = new JSONObject(jsonResult); String name = object.getString("name"); String verion = object.getString("version"); textView.setText(name + " - " + verion); } catch (JSONException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } private StringBuilder inputStreamToString(InputStream is) { String rLine = ""; StringBuilder answer = new StringBuilder(); BufferedReader rd = new BufferedReader(new InputStreamReader(is)); try { while ((rLine = rd.readLine()) != null) { answer.append(rLine); } } catch (IOException e) { e.printStackTrace(); } return answer; }}\[/code\]I tried both \[code\]http://127.0.0.1/test.php and http://localhost/test.php\[/code\] in HttpPost, It doesn't works.I checked my php file on the browser and that gives the result fine.Where am i Going wrong?Also i am working on a Mac, is that anyway related to the problem because of all the permission issues?
