Android จะใช้งาน method บน web service 2 method พร้อมกัน เขียนโค้ดอย่างไรดีครับ

private final String NAMESPACE = "http://proj.com";
	private final String URL = "http://132.146.4.52:8080/TestProjService/services/TestProjService?wsdl";
	private final String SOAP_ACTION = "http://132.146.4.52:8080/TestProjService/services/TestProjService/getResult";
	private final String METHOD_NAME = "getResult";
	private final String SOAP_ACTION2 = "http://132.146.4.52:8080/TestProjService/services/TestProjService/task";
	private final String METHOD_NAME2 = "task";

protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.result);

		// Permission StrictMode
		if (android.os.Build.VERSION.SDK_INT > 9) {
			StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
					.permitAll().build();
			StrictMode.setThreadPolicy(policy);
		}
try {
			SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

			final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
					SoapEnvelope.VER11);
			envelope.dotNet = true;
			envelope.setOutputSoapObject(request);

			HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
			
			androidHttpTransport.call(SOAP_ACTION, envelope);
			SoapObject result = (SoapObject) envelope.bodyIn;

			if (result != null) {
			} else {
				Toast.makeText(Result.this, "Web Service not Response!",
						Toast.LENGTH_SHORT).show();
			}
		} catch (IOException e) {
			e.printStackTrace();
		} catch (ArrayIndexOutOfBoundsException e) {
			e.printStackTrace();
		} catch (XmlPullParserException e) {
			e.printStackTrace();
		} catch (Exception e) {
			e.printStackTrace();
		}

Button start = (Button) findViewById(R.id.btStart);
start.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {
				try {
					SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME2);

					final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
							SoapEnvelope.VER11);
					envelope.dotNet = true;
					envelope.setOutputSoapObject(request);

					HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

					androidHttpTransport.call(SOAP_ACTION2, envelope);
					SoapObject result = (SoapObject) envelope.bodyIn;

					if (result != null) {
