// 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);

    CkJsonObject json = new CkJsonObject();
    json.Load("{ \"name\": \"John\", \"marbles\": 100 }");

    CkJsonArray jarr = new CkJsonArray();
    jarr.Load("[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]");

    //  Copy the contents of jar to a new array member named "stuff".
    json.AppendArrayCopy("stuff",jarr);

    Log.i(TAG, json.emit());
    //  Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

    //  Note: The contents of the array were copied.
    //  If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
    //  For example:
    jarr.AddIntAt(-1,2020);
    Log.i(TAG, jarr.emit());
    //  Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

    Log.i(TAG, json.emit());
    //  Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

  }

  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."
