我只是想用我的android示例项目做一个简单的Web服务,似乎无法让它工作。 这是我的代码:
private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://blah/Service1.asmx";
private final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
private final String METHOD_NAME = "HelloWorld";
private String TAG = "SOAP";
private static String message;
Button b;
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.textView1);
b = (Button) findViewById(R.id.button1);
//Button Click Listener
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
getMessage();
}
});
}
public void getMessage() {
//Create request
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Property which holds input parameters
PropertyInfo messagePI = new PropertyInfo();
//Set Name
messagePI.setName("Practice");
//Set Value
messagePI.setValue(messagePI);
//Set dataType
messagePI.setType(String.class);
//Add the property to request object
request.addProperty(messagePI);
//Create envelope
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
//Set output SOAP object
envelope.setOutputSoapObject(request);
//Create HTTP call object
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
//Invoke web service
androidHttpTransport.call(SOAP_ACTION, envelope);
//Get the response
SoapObject result = (SoapObject) envelope.bodyIn;
if(result !=null){
tv.setText(result.getProperty(0).toString());
}
//tv.setText("" + results);
} catch (Exception e) {
tv.setText(e.getMessage());
//e.printStackTrace();
}
}
当我单步执行时,它会在SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
行出错,说它来自AndroidRuntime Error
...我真的只是从教程中复制了这段代码,所以它应该可以工作但是可以'似乎弄明白为什么不。

这就是它现在错误的行androidHttpTransport.call(SOAP_ACTION, envelope);
答案 0 :(得分:0)
您需要将ksoap jar文件添加到项目中的libs目录中,以便在构建apk时,jar将被捆绑到其中。您获得的异常告诉我代码未正确捆绑,因此您找不到类错误。
