JSON Paths that need Double Quotes

See more JSON Examples

This example explains and demonstrates the situations where parts within a JSON path need to be enclosed in double-quotes. 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);

    // Imagine we have the following JSON:

    // 	{ 
    // 	  "Meta Data": { 
    // 	    "1: Symbol": "MSFT",
    // 	    "2: Indicator": "Relative Strength Index (RSI)",
    // 	    "3: Last Refreshed": "2017-07-28 09:30:00",
    // 	    "4: Interval": "15min",
    // 	    "5: Time Period": 10,
    // 	    "6: Series Type": "close",
    // 	    "7: Time Zone": "US/Eastern Time"
    // 	  },
    // 	  "Technical Analysis: RSI": { 
    // 	    "2017-07-28 09:30": { 
    // 	      "RSI": "38.6964"
    // 	    },
    // 	    "2017-07-27 16:00": { 
    // 	      "RSI": "50.0088"
    // 	    } 
    // 	} 

    // The path to the RSI valud 38.6964 is Technical Analysis: RSI.2017-07-28 09:30.RSI

    // Whenever a path part contains a SPACE or "." char, that part must be enclosed
    // in double quotes.  For example:

    CkJsonObject json = new CkJsonObject();
    json.LoadFile("qa_data/json/rsi.json");

    Log.i(TAG, "RSI: " + json.stringOf("\"Technical Analysis: RSI\".\"2017-07-28 09:30\".RSI"));

    // output is 38.6964

  }

  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."
