错误ksoap2序列化

Question

我尝试制作一个简单的应用程序来提取Web服务的字符串，我已经下载了ksopa2软件包，制作精良的数据和正确的数据（已在Internet教程上进行了测试），但我得到了下面的错误提示，您知道是？ 非常感谢你！

应用：

public class MainActivity extends Activity { 

private static final String SOAP_ACTION = "http://tempuri.org/devuelveString"; //Variables
private static final String METHOD_NAME = "devuelveString";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://localhost:52335/Service1.asmx";

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

    Button boton = (Button) findViewById(R.id.Bboton);

    boton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            InvocarWs(); //call the method

        }
    });
}

public void InvocarWs() {
    System.out.println("llama al metodo");
    try {

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11); // utilizar la version que
                                        // corresponda:11 o 12
        envelope.dotNet = true; // para WS ASMX, sólo si fue construido con
                                // .Net
        envelope.setOutputSoapObject(request);

        HttpTransportSE transporte = new HttpTransportSE(URL);

        transporte.call(SOAP_ACTION, envelope);

        SoapPrimitive resultado = (SoapPrimitive) envelope.getResponse();

        System.out.println("" + resultado.toString());

    } catch (Exception e) {
        System.out.println("catch");
    }
}

}

Answer 1

您需要将jar复制到项目中的libs目录中。 ADK从该文件夹中选择库，并将其转换为针对Dalvik优化的类。

Creating a folder "libs" in the project
Copying the external jars in to the folder
Refresh the folder
Go to properties -> Build path -> Add Jar (not external JAR)
Clean the project
Restart Eclipse

也尝试一下

Go to the Order and Export tab on the same popup window
Check the box against the newly added jar

Answer 2

只需将ksoap2 jar复制到您的libs文件夹即可。 然后从您的构建路径中将jar文件添加到您的项目中。

刷新您的项目并运行。 它将运行正常。

Answer 3

试试这个：

脚步：

步骤01：转到项目->项目属性-> Java构建路径->库->添加外部Jar

步骤02：从目标位置选择Jar文件

步骤03：在同一窗口中，选择库的下一个标签，即“订购并导出”

步骤04：订购和导出->选中您的图书馆复选框->确定

不要创建任何libs文件夹，它会自动创建。

我希望这对您有帮助... :)
