JSON Add Large Integer or Double

See more JSON Examples

Demonstrates how to add a large number (larger than what can be held in an integer), or a double/float value to a JSON document. 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);

    CkJsonObject json = new CkJsonObject();

    // To add a large integer, use AddNumberAt.

    // (an index of -1 indicates append).
    int index = -1;
    json.AddNumberAt(index,"bignum","8239845689346587465826345892644873453634563456");

    // Do the same for a double..
    json.AddNumberAt(index,"double","-153634.295");

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

    // Output:

    // 	{
    // 	  "bignum": 8239845689346587465826345892644873453634563456,
    // 	  "double": -153634.295
    // 	}

  }

  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."
