Performance tips for Lifecycle-aware components in Android?

            // Example of using LiveData with Lifecycle-aware components
            public class MyViewModel extends ViewModel {
                private final MutableLiveData userName = new MutableLiveData<>();

                public LiveData getUserName() {
                    return userName;
                }

                public void loadUserName() {
                    // Simulating a data load
                    userName.setValue("John Doe");
                }
            }
            
            public class MyActivity extends AppCompatActivity {
                private MyViewModel viewModel;

                @Override
                protected void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.activity_my);

                    viewModel = new ViewModelProvider(this).get(MyViewModel.class);
                    viewModel.getUserName().observe(this, name -> {
                        // Update UI with the user name
                        TextView userNameTextView = findViewById(R.id.userNameTextView);
                        userNameTextView.setText(name);
                    });
                    
                    viewModel.loadUserName(); // Load user name when activity is created
                }
            }
