HTTP POST (Duplicate Simple HTML Form POST)

Demonstrates how to duplicate a simple HTML form POST. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
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);

    boolean success = false;

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

    CkHttpRequest req = new CkHttpRequest();
    CkHttp http = new CkHttp();

    // This example simulates this FORM:
    // <form action="echoPost.asp" method="post">
    // First name: <input type="text" name="firstName"><br />
    // Last name: <input type="text" name="lastName"><br />
    // <input type="submit" value="Submit">
    // </form>
    // The online FORM is found at this URL:
    // https://www.chilkatsoft.com/simpleForm.html

    // Build an HTTP POST Request:
    req.put_HttpVerb("POST");

    // The FORM target is http://www.chilkatsoft.com/processPost.asp
    // An easy way of filling out most of the HTTP request object
    // is to call SetFromUrl:
    req.SetFromUrl("https://www.chilkatsoft.com/echoPost.asp");

    // Send form params using application/x-www-form-urlencoded
    req.put_ContentType("application/x-www-form-urlencoded");

    // The only remaining task is to add the params to the 
    // HTTP request object:
    req.AddParam("firstName","Matt");
    req.AddParam("lastName","Jones");

    // Send the HTTP POST and get the response.
    // The POST is being sent to chilkatsoft.com, on port 443 (using TLS)
    String domain = "chilkatsoft.com";
    int port = 443;
    boolean tls = true;

    // The HTTP POST is sent here:
    CkHttpResponse resp = new CkHttpResponse();
    success = http.HttpSReq(domain,port,tls,req,resp);
    if (success == false) {
        Log.i(TAG, http.lastErrorText());
        return;
        }

    // Display the HTML source of the page returned.
    Log.i(TAG, resp.bodyStr());

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
