我浏览了很多关于使用 android 使用 .net Web 服务的文章，但似乎我无法让它工作。

  • 我已经下载了“ksoap2-android-assembly-2.6.2-jar-with-dependencies” 并将其作为外部 jar 添加到我当前的项目中。

  • 我已经将 uses-permission android:name="android.permission.INTERNET"放在清单文件中。

当我调试程序并调用该函数时，应用程序说“应用程序* (* ) 已意外停止。请重试。”

我究竟做错了什么？这是我的代码：

private static final String NAMESPACE = "http://epson.com.ph/";
private static final String SOAP_ACTION = "http://epson.com.ph/TheMessage";
private static final String METHOD_NAME = "TheMessage";
private static final String URL = "http://10.0.2.2/DataAccess.asmx";

private void getData(){ 
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    //request.addProperty("selectStatement", "SELECT * FROM ALLDETAILS");

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

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
    TextView tv = (TextView)findViewById(R.id.txtPreview); 

    try { 
        androidHttpTransport.call(SOAP_ACTION, envelope); 
        Object result = (Object)envelope.getResponse();

        tv.setText(result.toString()); 
    } catch (Exception ex) { 
        messageBox(ex.getMessage()); 
        } 
}

logcat 错误是：

谢谢大家的回复，我已经有了解决办法。就像弗兰肯斯坦所说的那样，他给出的链接上的情况略有相同。

我在项目上放了一个libs文件夹并导入 ksoap jar。我只是想知道，为什么 libs 文件夹不会自动包含在每个项目中，如果我用不同的文件夹名称命名它，解决方案是否会起作用。
