Load a JSON Array

See more JSON Examples

The Chilkat JSON API requires the top-level JSON to be an object. Therefore, to load an array requires that it first be wrapped as an object. 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);

    boolean success = false;

    // Imagine we want to load this JSON array for parsing:
    String jsonArrayStr = "[{\"id\":200},{\"id\":196}]";

    // First wrap it in a JSON object by prepending "{ "array":" and appending "}"
    CkStringBuilder sbJson = new CkStringBuilder();
    sbJson.Append("{\"array\":");
    sbJson.Append(jsonArrayStr);
    sbJson.Append("}");

    CkJsonObject json = new CkJsonObject();
    json.Load(sbJson.getAsString());

    // Now we can get the JSON array
    CkJsonArray jArray = json.ArrayAt(0);

    // Do what you want with the JSON array...
    // For example:
    CkJsonObject jObjId = jArray.ObjectAt(0);
    Log.i(TAG, String.valueOf(jObjId.IntOf("id")));


  }

  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."
