儘管爲清單文件添加了Internet權限，但爲什麼仍然收到SocketException PermissionDenied異常？

Question

我想調用一個soap webservice，如下所示。我添加了互聯網權限清單文件，但我仍然得到異常（SocketException：權限被拒絕）。

class CallWebService extends AsyncTask<String, Void, String> { 

    @Override 
    protected String doInBackground(String... parameters) { 
     final DefaultHttpClient httpClient=new DefaultHttpClient(); 
     // request parameters 
     HttpParams params = httpClient.getParams(); 
     HttpConnectionParams.setConnectionTimeout(params, 10000); 
     HttpConnectionParams.setSoTimeout(params, 15000); 
     // set parameter 
     HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true); 

     // POST the envelope 
     HttpPost httppost = new HttpPost(parameters[0]); 
     // add headers 
     httppost.setHeader("soapaction", parameters[1]); 
     httppost.setHeader("Content-Type", "text/xml; charset=utf-8"); 

     String responseString=""; 
     try { 

      // the entity holds the request 
      HttpEntity entity = new StringEntity(parameters[2]); 
      httppost.setEntity(entity); 

      // Response handler 
      ResponseHandler<String> rh=new BasicResponseHandler(); 

      /*{ 
      // invoked when client receives response 
      public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException { 

      // get response entity 
      HttpEntity entity = response.getEntity(); 

      // read the response as byte array 
        StringBuffer out = new StringBuffer(); 
        byte[] b = EntityUtils.toByteArray(entity); 

        // write the response byte array to a string buffer 
        out.append(new String(b, 0, b.length));   
        return out.toString(); 
      } 
      }; 
      */ 
      responseString=httpClient.execute(httppost, rh); 

     } 
     catch (Exception e) { 
      Log.v("exception", e.toString()); 
     } 

     // close the connection 
     httpClient.getConnectionManager().shutdown(); 
     return responseString; 
    } 
}

您是否已將互聯網權限置於清單頂部（應用程序）級別（如下所示）。沒有錯誤報告，如果你把它低了下去，但你不會得到訪問互聯網......
