How to use Threading in an Android app?

Threading is a critical aspect of Android development that allows you to perform operations on different threads, improving the responsiveness of your app. In this example, we will explore how to use the `AsyncTask` class for background operations and how to update the UI thread safely.

    import android.os.AsyncTask;

    public class MyAsyncTask extends AsyncTask {

        @Override
        protected String doInBackground(Void... voids) {
            // Simulating a background operation
            try {
                Thread.sleep(2000); // Sleep for 2 seconds
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            return "Task Complete";
        }

        @Override
        protected void onPostExecute(String result) {
            // Update UI here
            System.out.println(result); // Replace with appropriate UI code
        }
        
        // Execute the AsyncTask
        public void executeTask() {
            new MyAsyncTask().execute();
        }
    }
