我有来自logcat的错误：

虽然我无法正确运行，但我已经尝试了所有我知道的内容。最后，我完全复制了代码来测试我的Web服务; http://mustafa-yildirim.blogspot.com/2010/09/android-net-web-servis-baglants.html以下是我的代码。

package com.project.newproject;
import java.io.IOException;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import org.ksoap2.*;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import org.xmlpull.v1.XmlPullParserException;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */

    private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
    private static final String METHOD_NAME = "HelloWorld";
    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String URL = "http://mysite/service1.asmx";

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

        final Button btn_goster = (Button) findViewById(R.id.btn_goster);
        final EditText edt_goster = (EditText) findViewById(R.id.edt_goster);

        btn_goster.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                        SoapEnvelope.VER11);
                envelope.dotNet = true;
                envelope.setOutputSoapObject(request);

                AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);

                SoapPrimitive result = null;
                try {
                    httpTransport.call(SOAP_ACTION, envelope);
                    result = (SoapPrimitive) envelope.getResponse();
                    edt_goster.setText(result.toString());
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    edt_goster.setText(e.getMessage());
                } catch (XmlPullParserException e) {
                    // TODO Auto-generated catch block
                    edt_goster.setText(e.getMessage());
                }

            }

        });

    }

一切都一样且没有错误，但是当我运行AVD或手机时，会显示一条名为“新项目已停止”的消息。我每次都得到它:(

Answer 1

在eclipse中点击右键点击项目选择构建工具＆gt;添加外部jar文件并选择ksoap2 jar文件。你还确定你已经下载了android的版本（不适用于j2me和其他平台）吗？您应该从code.google.com

下载它

我无法通过Android调用Web服务
