This small code snippet runs fine on my Mac's JVM. Unfortunately it crashes when executed on Android 4.2.
import java.net.HttpURLConnection;
import java.net.URL;
public class App
{
public static void main( String... arguments ) throws Exception
{
HttpURLConnection connection = (HttpURLConnection) new URL( "https://github.com" ).openConnection();
connection.setRequestMethod( "HEAD" );
System.out.println( connection.getResponseCode() + "" );
}
}
If I replace https://github.com
with https://www.facebook.com
it works fine but I'm failing to figure out why.
The exception does not contain a message; so here's at least the stack trace.
java.io.EOFException

Turned out this is a known bug in Android's class implementation. Calling Connection.setRequestProperty( "Accept-Encoding", "" );
before connecting can be used as workaround.
