Soap 1.2 android Please put a valid soap action

My.net webservice obviously works with soap 1.2 (by checking .wsdl), and I'm trying to access the helloworld web service for testing, but I ran into errors. I am trying to do this through an emulator, by the way.

So, when I use soap 1.2, I get an error that it "cannot process the request without a valid action parameter. Please put a valid soap." I want to know what I don’t have and what should I do.

Thank!

Things I've already done:

• Add permission for Android to use the Internet
• Change from soap versions 1.1 and 1.2
• Change from SoapObject to Object (for both soaps 1.1 and 1.2)
• Used 10.0.2.2 for the emulator
• Checked for errors when writing address and method names

My codes are:

 private static final String NAMESPACE = "http://localhost/WebService/";
 private static final String URL = "http://10.0.2.2:1672/Eventurous/WsEventurousMobile.asmx";
 private static final String HelloWorld_SOAP_ACTION = "http://localhost/WebService/HelloWorld";
 private static final String METHOD_NAME1 = "HelloWorld";



...
...

public static String GetHelloWorld() {

  SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME1);
  SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
     SoapEnvelope.VER12);
  envelope.dotNet = true;
  envelope.setOutputSoapObject(request);
  HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,60000);

  try {
   androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
    androidHttpTransport.call(HelloWorld_SOAP_ACTION, envelope);

   SoapObject response = (SoapObject)envelope.getResponse(); 
   String result = response.getProperty(0).toString(); 

   return result;
   } catch (Exception e) {
   return e.toString();
  }

 }
