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();

    // 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());
