我正在编写的应用程序有问题，该应用程序可在三星 S5300（Android OS 2.3.3）上运行，但不能在我的平板电脑（Prestigio Multipad 2 Ultra Duo 8.0 3G）上运行。它正在运行（Android OS 4.1）
该应用程序从 IOIO 板上获取一些信息，例如时间戳和 ADC 值，并将其发布到服务器。这适用于三星手机。使用平板电脑，它会在发送数据部分时大放异彩。
这是我的代码片段：
public void postData()
{
String urlS = "https://posttestserver.com/post.php?dump&html&dir=oan";
//String urlS = "https://placidblue.no-ip.biz/cgi-bin/data_input.py";
//String urlS = "http://placidblue.no-ip.biz/cgi-bin/data_input.py";
HttpClient httpclient = new DefaultHttpClient(); // Create a new HttpClient and Post Header
HttpPost httppost = new HttpPost(urlS);
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("LAT", TransferLat));
nameValuePairs.add(new BasicNameValuePair("LON", TransferLon));
nameValuePairs.add(new BasicNameValuePair("TIM", TransferTim));
nameValuePairs.add(new BasicNameValuePair("POL", TransferPol));
nameValuePairs.add(new BasicNameValuePair("CON", TransferCon));
try {
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
} catch (UnsupportedEncodingException e) {
Log.d("General","UnsupportedEncodingException.xxx");
e.printStackTrace();// writing error to Log
}
Log.d("General Log","Sending_data.xxx");
HttpResponse response = httpclient.execute(httppost); // Execute HTTP Post Request
Log.d("HttpResponse:", response.toString()+"xxx"); // writing response to log
Log.d("General","Data_send_complete.xxx");
}catch (IllegalStateException e) {
Log.d("General","Illegal_State1.xxx");
e.printStackTrace();
Log.d("General","Illegal_State2.xxx");
}
catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
// writing error to Log
e.printStackTrace();
}
}//end postData
我得到的 logcat 错误如下：

我相信新操作系统的权限甚至可能是一些安全问题？我已经在清单中设置了适当的互联网权限。
任何意见，将不胜感激。问候
