[英]Consuming SOAP web services from Android
I am trying to create a project in android studio to consume a web service from android. 我试图在android studio中创建一个项目,以使用android的网络服务。 My app compiles without error but when I run it the required output is not displayed as if it is not working at all.
我的应用程序编译没有错误,但是当我运行它时,所需的输出没有显示出来,好像它根本无法正常工作。

Note: I copied this code from internet and made some adjustments according to my requirements. 注意:我从互联网复制了此代码,并根据需要进行了一些调整。 But, I'm new in android studio so most probably those adjustments did something wrong.
但是,我是android studio的新手,所以很可能这些调整做错了什么。
Try this. 尝试这个。
public class test extends AsyncTask<String,Void,Integer>{
int a;
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Integer doInBackground(String... params) {
String value1 = params[0];
String value2 = params[1];
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("a", Integer.valueof(value1));
request.addProperty("b", Integer.valueof(value2));
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL, 60 * 10000);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive soapPrimitive = (SoapPrimitive) envelope.getResponse();
a = new Integer(Integer.valueOf(soapPrimitive.toString()));
}catch (Exception e){
}
return a;
}
@Override
protected void onPostExecute(Integer integer) {
super.onPostExecute(integer);
Toast.makeText(MeetActivity.this, ""+String.valueOf(integer), Toast.LENGTH_SHORT).show();
}
}
This is my final code and now its working perfectly fine. 这是我的最终代码,现在可以正常工作。 Thanks for help though.
谢谢您的帮助。
