Description: Learn how to effectively migrate from older APIs to the modern Fragment lifecycle in Android development to improve app performance and user experience.

Example of Migrating to Fragment Lifecycle

// Old API example public class OldFragment extends Fragment { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Initialization code } @Override public void onDestroy() { super.onDestroy(); // Clean up code } } // New Fragment lifecycle implementation public class NewFragment extends Fragment { @Override public void onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_layout, container, false); // Initialize UI components return view; } @Override public void onStart() { super.onStart(); // Code to run when the fragment is visible to the user } @Override public void onStop() { super.onStop(); // Code to clean up resources when the fragment is no longer visible } }
