You need to create writer for string output.

@SuppressWarnings("null")
public static String CreateXMLString() throws IllegalArgumentException, IllegalStateException, IOException
{
    XmlSerializer xmlSerializer = Xml.newSerializer();
        StringWriter writer = new StringWriter();

    xmlSerializer.setOutput(writer);

    //Start Document
    xmlSerializer.startDocument("UTF-8", true); 
    xmlSerializer.setFeature("http://xmlpull.org/v1/doc/features.html#indent-output", true);
    //Open Tag <file>
    xmlSerializer.startTag("", "file");

    xmlSerializer.startTag("", "something");
    xmlSerializer.attribute("", "ID", "000001");

    xmlSerializer.startTag("", "name");
    xmlSerializer.text("CO");
    xmlSerializer.endTag("", "name");

    xmlSerializer.endTag("", "something");



    //end tag <file>
    xmlSerializer.endTag("", "file");
    xmlSerializer.endDocument();

    return writer.toString();
}

And the output string is like this:

   <?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
   <file>
    <something ID="000001">
    <name>
    CO
    </name>
    </something>
   </file>

But i don't know how to send it.Maybe, you can convert this string into bytes.

FileOutputStream fileos = null;
try{
    fileos = new FileOutputStream(newxmlfile);

} catch(FileNotFoundException e) {
     Log.e("FileNotFoundException",e.toString());
}
XmlSerializer serializer = Xml.newSerializer();

try {

  serializer.endTag(null,"root");
  serializer.endDocument();
  serializer.flush();
