Emit JSON Array to StringBuilder

See more JSON Examples

Demonstrates how to write a JSON array to a Chilkat StringBuilder 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;

    CkJsonArray a = new CkJsonArray();
    success = a.Load("[ 1,2,3,4 ]");

    // We could get the JSON array as a string...
    String s = a.emit();
    Log.i(TAG, s);

    // But what if the JSON array contains a huge amount of data,
    // and we don't want to marshal it all from Chilkat's internal
    // native code to a string in our programming language?

    // You can instead emit to a Chilkat StringBuilder
    CkStringBuilder sb = new CkStringBuilder();
    a.EmitSb(sb);

    // Perhaps the StringBuilder object can be passed to other methods..
    // Chilkat typically provides methods where a potentially large string
    // can be passed in via a StringBuilder object..

    // Or perhaps you wish to save to a file..
    success = sb.WriteFile("c:/temp/qa_output/a.json","utf-8",false);

  }

  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."
