HTTP POST在应用程序中工作但不在服务中

Question

HTTP POST

我的android应用程序需要对PHP脚本执行HTTP发布。帖子需要在服务中发生。出于某种原因，POST在服务中运行时会获得连接超时，但如果我将方法复制到我的应用程序的onCreate事件并运行，它可以正常工作。我不知道会有什么不同。 这是我的方法

    String url = "http://myurl/" +
  "?tmpl=javascript" +
  "&mode=recieved" + 
  "&id=" + id;
  URI uri = null;
  try {
   url = url.replace(" ", "%20");
   uri = new URI(url);
  } catch (URISyntaxException e1) {
   // TODO Auto-generated catch block
   e1.printStackTrace();
  }
  HttpGet httpGet = new HttpGet(uri);
  HttpParams httpParameters = new BasicHttpParams();
  // Set the timeout in milliseconds until a connection is established.
  int timeoutConnection = 10000;
  HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
  // Set the default socket timeout (SO_TIMEOUT) 
  // in milliseconds which is the timeout for waiting for data.
  int timeoutSocket = 10000;
  HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

  DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
  try {
   HttpResponse response = httpClient.execute(httpGet);
  } catch (ClientProtocolException e) {
   System.out.println(e.getLocalizedMessage());
   e.printStackTrace();
  } catch (IOException e) {
   System.out.println(e.getLocalizedMessage());
   e.printStackTrace();
  }

Android清单声明了这样的服务

<service android:name=".Notifications.PushService" 
       android:label="Application Notifications Service">

    </service>

我确实在权限中使用了互联网。 任何帮助将不胜感激。

谢谢！
