Android应用程序未启动

我试图使用的代码，从我自己的应用程序，但它不工作

1）我使用MySQL工作台创建了一个数据库

2）在Eclipse（Juno）中，我使用AXISv2创建了Web服务

3）我使用ADK创建了应用程序

首先运行MySQL服务器，然后在ApacheTomcat中运行webservice。这个过程并不是一个真正的问题。我检查了一下，一切都在运行。然而，当我运行这个应用程序时，Android就停止了工作

这是logcat。

公共类MainActivity扩展了活动{

/**在首次创建活动时调用*/
@凌驾
创建时的公共void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_main）；
SoapObject请求=新的SoapObject（名称空间、方法名称）；
SoapSerializationEnvelope=新的SoapSerializationEnvelope（SoapEnvelope.VER11）；
envelope.setOutputSoapObject（请求）；
HttpTransportSE ht=新的HttpTransportSE（URL）；
试一试{
ht.呼叫（SOAP_动作、信封）；
SoapPrimitive响应=（SoapPrimitive）信封.getResponse（）；
SOAPs=响应；
字符串str=s.toString（）；
String resultArr[]=str.split（&）；//结果字符串将拆分并存储在数组中
TextView tv=新的TextView（此）；
对于（int i=0；我在你的项目中添加了lib文件？？？我将ksoap2添加到android应用程序中，并将JDBC添加到web服务器中。首先清理你的项目并再次运行！！！！！我已经这样做了，但仍然不起作用。java.lang.NoClassDefFoundError:org.ksoap2.serialization.SoapObject这行表示你的文件不可用，请再次检查！！！！
