Android应用程序在模拟器上工作，但在手机上不工作（连接问题）

我有一个应用程序，通过php API从google日历获取信息，问题是该应用程序在模拟器上工作，但当我尝试在手机上使用它时，只有一个常规的黑屏，没有任何信息。这似乎是一个连接问题（与我最初的想法不同）。 仿真器android版本是2.3.3，我的手机也是如此

这是我的代码：

 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;

    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("contact",""));
    HttpResponse response=null;

        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{

        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.write(returnString);
        fw.close();

对于（int i=1；i我终于找到了问题的根源。我没有将xampp的设置更改为允许从oustide连接，我只在本地工作。

嗨，你能详细介绍一下吗s、 比如如何以及如何更改axmpp设置？我想我也面临同样的问题。我的问题是上一部分中的httpd-xamp.conf（新安全概念）这是本地所有execpt的拒绝，所以您必须更改为您希望允许的。您好，您能详细说明一下这一点吗，比如如何以及如何更改axmpp设置？我想我也面临着同样的问题。我的问题是上一部分的httpd-xamp.conf（新安全概念）中的问题这是对拒绝从所有执行为本地，所以你必须改变到什么你想允许。
