Question

我是Android编程新手并开发了这个应用程序，它接受Kg中的参数并使用Web服务将其转换为克但在模拟器上运行时应用程序显示“不幸的是Android WebService已停止”以及logcat中的主要问题被显示“找不到org.ksoap2.serialization.SoapObjectare”虽然我已经包含了“ksoap2-android-assembly-2.5.4-jar-with-dependencies”jar文件...请帮忙

这是我的代码：

package com.sencide;



private final String NAMESPACE = "http://www.webserviceX.NET/";
private final String URL = "http://www.webservicex.net/ConvertWeight.asmx";
private final String SOAP_ACTION = "http://www.webserviceX.NET/ConvertWeight";
private final String METHOD_NAME = "ConvertWeight";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    String weight = "3700";
    String fromUnit = "Grams";
    String toUnit = "Kilograms";

    PropertyInfo weightProp =new PropertyInfo();
    weightProp.setName("Weight");
    weightProp.setValue(weight);
    weightProp.setType(double.class);
    request.addProperty(weightProp);

    PropertyInfo fromProp =new PropertyInfo();
    fromProp.setName("FromUnit");
    fromProp.setValue(fromUnit);
    fromProp.setType(String.class);
    request.addProperty(fromProp);

    PropertyInfo toProp =new PropertyInfo();
    toProp.setName("ToUnit");
    toProp.setValue(toUnit);
    toProp.setType(String.class);
    request.addProperty(toProp);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try 
    {
        androidHttpTransport.call(SOAP_ACTION, envelope);
        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
        Log.i("myApp", response.toString());

        TextView tv = new TextView(this);
        tv.setText(weight+" "+fromUnit+" equal "+response.toString()+ " "+toUnit);
        setContentView(tv);

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

}

Answer 1

将jar添加到'libs'文件夹而不是lib文件夹，然后添加到Build Path。

Answer 2

您是否已将JAR添加到构建路径？

在您的包浏览器中，右键单击JAR文件并选择：Build Path＆gt;添加到构建路径

另外，如果您只是进行简单的转换，为什么要使用WebService？没有连接到互联网，这可以更快地完成...只是我的额外两美分

Answer 3

我做了同样的事情并解决了Java Build Path选项，Order and Export选项卡中kosoap2库上的问题检查复选框。

Answer 4

我做了如下：

将jar添加到'libs'文件夹，然后添加到Build Path。
在“Java构建路径”选项的“订购和导出”选项卡中选中kosoap2库上的复选框。

问题解决了。

不幸的是，Android WebService已停止
