これは、このビデオを使用して webservice を呼び出すために記述したコードです。実行すると、89.6 ではなくエラー文字列が表示されました。

package com.flafel.myTest;

public class FirstScreen extends Activity {
    /** Called when the activity is first created. */
    private static final String SQAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
    private static final String METMOD_NAME = "CelsiusToFahrenheit";
    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
    TextView tv;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


                tv = (TextView) findViewById(R.id.textView1);

                SoapObject Request = new SoapObject(NAMESPACE, "Method_Name");
                Request.addProperty("Celsius", "32");

                SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
                        SoapEnvelope.VER11);
                soapEnvelope.dotNet = true;
                soapEnvelope.setOutputSoapObject(Request);

                HttpTransportSE aht = new HttpTransportSE(URL);
                aht.debug=true;


                try {

                    aht.call(SQAP_ACTION, soapEnvelope);

                    SoapPrimitive resultString = (SoapPrimitive) soapEnvelope
                            .getResponse();
                    int count = resultString.getAttributeCount();
                    tv.setText("Status:" + resultString);

                } catch (Exception e) {
                    e.printStackTrace();
                }

            }       
}

出力は次のとおりです。

Hello World,FirstScreen!

自分の場所にmethod_nameを記述しなかったためです。

あなたのコード：

SoapObject Request = new SoapObject(NAMESPACE, "Method_Name");

真のコード：

SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
