package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkHttp http = new CkHttp();

    boolean success;

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // This example uses a live web service at:
    // http://www.webservicex.net/uklocation.asmx
    // It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

    // The SOAP XML will look like this:
    // <?xml version="1.0" encoding="utf-8"?>
    // <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    //   <soap:Body>
    //     <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
    //       <PostCode>string</PostCode>
    //     </GetUKLocationByPostCode>
    //   </soap:Body>
    // </soap:Envelope>

    // For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
    // The SOAP XML for this example may be downloaded from:
    // http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
    CkXml xml = new CkXml();
    success = xml.LoadXmlFile("ukPostCodeSoap.xml");
    if (success != true) {
        Log.i(TAG, xml.lastErrorText());
        return;
        }

    String strXml = xml.getXml();

    int responseStatusCode;

    // We'll need to add this in the HTTP header:
    // SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode");

    // Some services expect the content-type in the HTTP header to be "application/xml" while
    // other expect text/xml.  The default sent by Chilkat is "application/xml", but this web service
    // expects "text/xml".  Therefore, change the content-type:
    http.SetRequestHeader("Content-Type","text/xml; charset=utf-8");

    // The endpoint for this soap service is:
    String endPoint = "http://www.webservicex.net/uklocation.asmx";

    // Note: This particular web service was live and functioning at the time this example
    // was written.  It is possible that as time progresses, this web service will no longer
    // be availble...
    CkHttpResponse resp = http.PostXml(endPoint,strXml,"utf-8");
    if (http.get_LastMethodSuccess() != true) {
        Log.i(TAG, http.lastErrorText());
        Log.i(TAG, "LastHeader:");
        Log.i(TAG, http.lastHeader());
        return;
        }

    responseStatusCode = resp.get_StatusCode();
    // You may wish to verify that the responseStatusCode equals 200...
    Log.i(TAG, "Response Status Code: " + String.valueOf(responseStatusCode));

    // You may examine the exact HTTP header sent with the POST like this:
    Log.i(TAG, "LastHeader:");
    Log.i(TAG, http.lastHeader());

    // Examine the XML returned by the web service:
    Log.i(TAG, "XML Response:");
    CkXml xmlResp = new CkXml();
    xmlResp.LoadXml(resp.bodyStr());
    Log.i(TAG, xmlResp.getXml());

      // then you will see the following error message at application startup:
