www,tempuri.org が提供する Web サービスを呼び出すコードがあります。アプリケーションを実行しようとしているときに、アプリケーションが予期せず停止し、「残念ながら、MyTest が停止しました」というメッセージが表示されます。これが私の Java ファイルです -
MainActivity.java :-
package com.example.mytest;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
public static final String SOAP_ACTION = "http://tempuri.org/CelciusToFarenheit";
public static final String METHOD_NAME = "CelciusToFarenheit";
public static final String NAMESPACE= "http://tempuri.org/";
public static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
TextView tv;
SoapEnvelope se;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv= (TextView) findViewById(R.id.TextView01);
SoapObject Request=new SoapObject(NAMESPACE,METHOD_NAME);
Request.addProperty("Celcius","32");
SoapSerializationEnvelope sse = new SoapSerializationEnvelope (se.VER11);
sse.dotNet=true;
sse.setOutputSoapObject(Request);
HttpTransportSE abt = new HttpTransportSE(URL);
try
{
abt.call(SOAP_ACTION,se);
SoapObject resultString=(SoapObject)sse.getResponse();
String resultData=resultString.getProperty(0).toString();
tv.setText("Status :"+resultString);
}
catch(Exception e)
{
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
activity_main.xml :-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"

tools:context=".MainActivity" >
<TextView
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
</RelativeLayout>
logcat は次のとおりです。

AndroidでWebサービスを開発するのは初めてです。これをどうするか教えてください。
