To send a JSON object from CodeIgniter to Android, you can follow these steps:

  1. Create a controller in CodeIgniter that will handle the request and return a JSON response. For example:
1
2
3
4
5
6
7

class Api extends CI_Controller {
    
    public function get_data() {
        $data = array('name' => 'John Doe', 'age' => 30, 'city' => 'New York');
        header('Content-Type: application/json');
        echo json_encode($data);
    }
}


  1. Create an Android application that will make a request to the CodeIgniter API and parse the JSON response. Here's an example of how you can do this in Java using Volley library:

String url = "http://yourdomain.com/api/get_data";

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, null,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                try {
                    String name = response.getString("name");
                    int age = response.getInt("age");
                    String city = response.getString("city");
                    
                    // Do something with the data
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                error.printStackTrace();
            }
        });

RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(jsonObjectRequest);


  1. Make sure to add the necessary permissions in your AndroidManifest.xml file to allow your app to connect to the internet:
1
<uses-permission android:name="android.permission.INTERNET" />


By following these steps, you will be able to send a JSON object from CodeIgniter to Android and handle the response in your Android application.
