// 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 arr = new CkJsonArray(); CkJsonObject obj = new CkJsonObject(); // Create a new and empty JSON object in the 1st position of the JSON array // and return the reference in the last argument. arr.AddObjectAt2(0,obj); obj.UpdateString("Name","Otto"); obj.UpdateInt("Age",29); obj.UpdateBool("Married",false); // Create a new and empty JSON object in the 2nd position of the JSON array // and return the reference in the last argument. arr.AddObjectAt2(1,obj); obj.UpdateString("Name","Connor"); obj.UpdateInt("Age",43); obj.UpdateBool("Married",true); // Create a new and empty JSON object in the 3rd position of the JSON array // and return the reference in the last argument. arr.AddObjectAt2(2,obj); obj.UpdateString("Name","Ramona"); obj.UpdateInt("Age",34); obj.UpdateBool("Married",true); // Examine what we have: arr.put_EmitCompact(false); Log.i(TAG, arr.emit()); // The output is: // [ // { // "Name": "Otto", // "Age": 29, // "Married": false // }, // { // "Name": "Connor", // "Age": 43, // "Married": true // }, // { // "Name": "Ramona", // "Age": 34, // "Married": true // } // ] } 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.
