Android DNS MX record lookup

Question

I want to lookup dns mx records an the android platform. When using http://www.dnsjava.org on android new Lookup("gmail.com", Type.MX).run(); always returns null.

    import org.xbill.DNS.Lookup;
    import org.xbill.DNS.MXRecord;
    import org.xbill.DNS.Record;
    import org.xbill.DNS.TextParseException;
    import org.xbill.DNS.Type;


List<String> targets = new ArrayList<String>();
Record[] records;  

    records = new Lookup("gmail.com", Type.MX).run();

    for (int i = 0; i < records.length; i++) {
     MXRecord mx = (MXRecord) records[i];
     targets.add("Host " + mx.getTarget() + " has preference  "+ mx.getPriority());
    }

Any ideas or alternatives? Thanks!

Finally forgot to set the permission and unfortunately no exception has been thrown...

<uses-permission android:name="android.permission.INTERNET" />
