Example: Http.HttpSb method

Shows how to use the HttpSb method to send an HTTP POST request with a StringBuilder as the request body. The example sends the following request:

POST /echo_request_body.asp HTTP/1.1
Host: chilkatsoft.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

// Important: Don't forget to include the call to System.loadLibrary

import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.

    //  This URL echoes the contents of the request body, letting us view it.
    String url = "https://chilkatsoft.com/echo_request_body.asp";

    //  Send a POST with the contents of the StringBuilder in the HTTP request body.
    CkHttpResponse resp = new CkHttpResponse();
    success = http.HttpSb("POST",url,sb,"utf-8","application/json",resp);

        }

    Log.i(TAG, "Response Status Code: " + String.valueOf(resp.get_StatusCode()));

    //  Examine the request we sent.
    //  The LastHeader property stores the HTTP request header of the most recent request sent,
    //  and in this instance, the response body mirrors the request body.
