// 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);

    // This example requires Chilkat v9.5.0.63 or greater.

    CkJsonObject json = new CkJsonObject();
    json.put_EmitCompact(false);

    // The UpdateString method updates or adds a string member.
    // It also auto-creates the objects and/or arrays that
    // are missing.  For example:
    json.UpdateString("test.abc[0].xyz","Chicago Cubs");

    // The JSON now contains:
    Log.i(TAG, json.emit());

    // {
    //   "test": {
    //     "abc": [
    //       {
    //         "xyz": "Chicago Cubs"
    //       }
    //     ]
    //   }

    json.UpdateString("test.abc[0].xyz","Chicago Cubs are going to win the World Series!");
    Log.i(TAG, json.emit());

    // {
    //   "test": {
    //     "abc": [
    //       {
    //         "xyz": "Chicago Cubs are going to win the World Series!"
    //       }
    //     ]
    //   }

  }

  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."
