// It's used in the lifecycle of an activity to perform setups and preparations
// before the activity becomes visible to the user.
@Override
protected void onStart() {
    super.onStart();

    // Set up navigation and other UI elements here
    // This is done before the activity is fully visible to the user
    // to ensure everything is ready when it's displayed on the screen.
    
    // You can set up event listeners, start services, etc.
    
    // This is useful when you need certain actions to be performed before
    // the user can interact with the activity.
}

// This is the onCreate method, which is called after onStart.
// Here, the initial setup of the activity is done, like configuring the UI and preparing data.
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    
    // Other initial configurations can be done here.
