Android 应用程序在模拟器上工作但在手机上不工作（连接问题）

Question

I have an application that gets information from google calendar by getting them from the php API, the issue is that the app works on the emulator but when I try to use it on my phone there is only a regular black screen with no information. It seems to be a connection issue (unlike my first thought). The emulator android version is 2.3.3 and same thing for my phone.

This is my code:

 public class AgendaActivity extends Activity {
    /** Called when the activity is first created. */
  public static final String CAL= "http://192.168.1.58/calendar.php";
  ListView vue;
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
  vue = (ListView) findViewById(R.id.listView1);
      List<HashMap<String, String>> liste = new ArrayList<HashMap<String,String>>();       
      HashMap<String, String> element;
    String result = getServerData(CAL);
    String[] chaine = result.split(";");
    for(int i=1;i<chaine.length-1;i++)
    {
                String[] event = chaine[i].split(":");
                element = new HashMap<String, String>();
                element.put("titre", event[1]);
                element.put("date",event[3]+":"+event[4] );
                liste.add(element);
    }
      ListAdapter adapter = new SimpleAdapter(this,  
            liste,
            android.R.layout.simple_list_item_2,
            new String[] {"titre", "date"}, 
            new int[] {android.R.id.text1, android.R.id.text2 });
      vue.setAdapter(adapter);      
}
private String getServerData(String returnString)  {    
    InputStream is = null;
    String result = "";
    File file = new File("sdcard/event.txt");
    FileWriter fw;
    FileReader fr;
    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("contact",""));
    HttpResponse response=null;
    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(returnString);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
         response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();   
    }catch(Exception e){
        Log.e("log_tag", "Error in http connection " + e.toString());
        String str = "";
        int i = 0;  
        try {
            fr =new FileReader(file);
            while((i = fr.read()) != -1)
                str += (char)i;
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        returnString=str;
        return returnString;    
    }
    try{
        BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        result=sb.toString();
    }catch(Exception e){
        Log.e("log_tag", "Error converting result " + e.toString());
    }
    try{
        JSONArray jArray = new JSONArray(result);   
        for(int i=0;i<jArray.length();i++)
        {
            JSONObject json_data = jArray.getJSONObject(i);
            returnString = ""+ json_data;
        }
        }catch(JSONException e)
    {  
        returnString=e.toString();
    }
    try {
            fw = new FileWriter(file);
        fw.write(returnString);
        fw.close();
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return returnString; }      
 }

The app on the simulator works fine but, when i launch the app i get on the logcat in the error section:

Any ideas?

I finally found where the problem came from. I didn't change the setting of my xampp to allow connection from oustide i was working on local only.
