(Android™) Load JSON Data at Path

Demonstrates how to load JSON data into a path within a JSON database. For example, we begin with this JSON:

{
  "a": 1,
  "b": 2,
  "c": {
    "x": 1,
    "y": 2
  }
}

{
  "a": 1,
  "b": 2,
  "c": {
    "mm": 11,
    "nn": 22
  }
}

    Log.i(TAG, json.emit());

    String q = "{\"mm\": 11, \"nn\": 22}";

    CkJsonObject c = json.ObjectOf("c");
    c.Load(q);

    // See that x and y are replaced with mm and nn.
    Log.i(TAG, json.emit());

  }

      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."
