Android模拟器使用KSOAP2调用WebService

项目需要Android去访问webservice，网上找了很多例子、中英文网站，每次运行都是出现错误“The application ***(process 包名) has stopped unexpectedly.Please try again “ ，困扰了好几天，是因为Eclipse导入ksoap2-android-assembly-2.4-jar-with-dependencies.jar包的时候的方式的问题。

之前导入jar包的时候，右键工程 Build path, java build path,选择libraries，在右边的按钮中点击“Add Library”，选择“User library”,点击“下一步”，点击“User librarys”按钮，在出现的界面中点击“New..”按钮，在弹出的界面中随便起一个名字，点击“确定”，点击“Add jars”按钮选择第三方jar包，点击“确定”完成操作。

后来右键工程，Build path,java build path,选择libraries,在右边的按钮中点击“Add External JARs”,然后选择合适的jar包。

还有一个问题就是Android模拟器访问Tomcat上部署的webservice程序时，不能用localhost 或者本级IP，Android默认访问本机地址为10.0.2.2。

SoapObject request = new SoapObject(SOAP_ACTION, METHOD_NAME);
request.addProperty("userName", "eric");
request.addProperty("userPwd", "831987");
System.out.println("-----------------------1");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
System.out.println("-----------------------2");
envelope.setOutputSoapObject(request);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);

androidHttpTransport.call(SOAP_ACTION, envelope);

System.out.println("-----------------------5");

// SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
Object result = (Object)envelope.getResponse();

System.out.println("-----------------------6");
// String xy = resultsRequestSOAP.getProperty(0).toString();

if(result.toString().equals("true"))
{
view1.setText("返回数据成功");
}
else
{
view1.setText("返回数据失败");
}

System.out.println("result: "+result);
}
catch (Exception e)
{
e.printStackTrace();
}

}
}
