如何使用来自 android 客户端的 ksoap2 调用基于 java 的 wsdl webservice？

Question

我是安卓新手。 我必须使用 ksoap2 从 android 客户端调用基于 java 的 wsdl webservice。 谁能帮我？ 我尝试打电话但收到 XmlPullParserException。

这是我使用 ksoap 的一个类

import java.io.IOException;

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 org.xmlpull.v1.XmlPullParserException;

        /**
         * 
         * @param result
         * @param mode also used for error
         */

    }

    private static KSOAPAsync mSearchAsync = null;

    public static final int ERROR_UNDEFINED = -1;

    public static final int MODE_WEATHER = 1;

    public static void startGetWeatherData(ResultListener listener, String city){

        mSearchAsync = new KSOAPAsync(listener, MODE_WEATHER);
        mSearchAsync.execute(city);
    }

    public static void startGetAddition(ResultListener listener, String x, String y){

        mSearchAsync = new KSOAPAsync(listener,MODE_CALCULATOR);

    }
