Demonstrates how to send a JSON PUT and get the JSON response body. 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 assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

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

    // The PUT request to be sent will look like this:

    // PUT /request HTTP/1.1
    // Content-Type: application/jsonrequest
    // Cookie: JSESSIONID=1234
    // Content-Encoding: identity
    // Host: json.penzance.org
    // Accept: application/jsonrequest
    // Accept-Encoding:
    // Content-Length: 72
    // 
    // {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

    // First, remove default header fields that would be automatically
    // sent.  (These headers are harmless, and shouldn't need to 
    // be suppressed, but just in case...)
    http.put_AcceptCharset("");
    http.put_UserAgent("");
    http.put_AcceptLanguage("");

    // Suppress the Accept-Encoding header by disallowing 
    // a gzip response:
    http.put_AllowGzip(false);

    // If a Cookie needs to be added...
    http.SetRequestHeader("Cookie","JSESSIONID=1234");

    // Add the Content-Encoding: identity header.
    http.SetRequestHeader("Content-Encoding","identity");

    // Modify the default "Accept" header:
    http.put_Accept("application/jsonrequest");

    String jsonText = "{\"user\":\"doctoravatar@penzance.com\",\"forecast\":7,\"t\":\"vlIj\",\"zip\":94089}";

    // IMPORTANT: Make sure to change the URL, JSON text,
    // and other data items to your own values.  The URL used
    // in this example will not actually work.

    CkHttpResponse resp = new CkHttpResponse();
    success = http.HttpStr("PUT","http://json.penzance.org/request",jsonText,"utf-8","application/jsonrequest",resp);
    if (success == false) {
        Log.i(TAG, http.lastErrorText());
        return;
        }

    Log.i(TAG, "Response status code: " + String.valueOf(resp.get_StatusCode()));
    Log.i(TAG, "Response JSON:");
