Trying to get XML from an URL

Question

Previously, I used the the XML file from the assets folder. The app can read it very well. The next step I want put this XML on the web server. But at this stage, the app cannot recognize any data. It confused me couple of days.

AssetManager asset = getAssets();
InputStream input = asset.open("student.xml");
List<Student> list = ParserByPULL.getStudents(input);

Everything works fine if the file in assets folder. Then I tried to get it from an URL.

String path = "http://fthgyj.tup632.cnaaa11.com/student.xml";
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("GET");
InputStream input = url.openConnection().getInputStream(); 
List<Student> list = ParserByPULL.getStudents(input);

I have added the permission of connecting the INTERNET at manifest file. Does anyone has an idea about this?

So what's going wrong then? Do you get exception or what, just empty response? — vilpe89, Apr 02 '14 at 10:18
tell us exact symptoms of your problem. Making us guess is not nice and besides you won't get your answer — kiruwka, Apr 02 '14 at 10:29
I am sorry. Nothing shows on screen. But the app can run as normal(No error on the logcat). — user3421634, Apr 02 '14 at 10:54

I think you need to call

conn.connect();
InputStream input = conn.getInputStream();

And then check if you got the xml fetched:

BufferedReader reader = new BufferedReader(new InputStreamReader(input));
StringBuilder builder = new StringBuilder();
String line;

while ((line = reader.readLine()) != null) {
    builder.append(line);
}
reader.close();
Log.d("tag", "output: " + builder.toString());
