Android 应用程序可在模拟器上运行但不能在手机上运行(连接问题)

Question

我有一个应用程序通过从 php API 获取信息来从谷歌日历获取信息，问题是该应用程序可以在模拟器上运行但是当我尝试在我的手机上使用它时只有一个普通的黑屏没有信息。这似乎是一个连接问题(与我的第一个想法不同)。模拟器 android 版本是 2.3.3 和我的手机一样。

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;
    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; }      
 }

模拟器上的应用程序运行良好，但是，当我启动该应用程序时，我在错误部分出现了 logcat:

有什么想法吗？

终于找到问题出在哪里了。我没有更改我的 xampp 设置以允许来自 oustide 的连接，我只在本地工作。
