I am trying to make a simple Android app that can retrieve lottery numbers from a website (https://www.lottostat.dk/rssfeed.php). I have tried using the example code provided here (and inserted below): Using Java to pull data from a webpage?
The example code works great when using the original target website (Using Java to pull data from a webpage?) and I can read the entire underlying html code in the output in Android Studio. But when I change the target website to the one I want to get my data from (https://www.lottostat.dk/rssfeed.php) there is no output (br.readLine() returns null).
What could be the problem here? Do I perhaps need a different solution for reading the .php website (even though the underlying code seems to be plain XML)?
Here's the working original sample code for reference:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class DownloadPage {
public static void main(String[] args) throws IOException {
// Make a URL to the web page
URL url = new URL("http://stackoverflow.com/questions/6159118/using-java-to-pull-data-from-a-webpage");
// Get the input stream through URL Connection
URLConnection con = url.openConnection();
InputStream is =con.getInputStream();
// Once you have the Input Stream, it's just plain old Java IO stuff.
// For this case, since you are interested in getting plain-text web page
// I'll use a reader and output the text content to System.out.
// For binary content, it's better to directly read the bytes from stream and write
// to the target file.
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line = null;
// read each line and write to System.out
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
