- Notifications: Creating and managing notifications for app alerts (e.g., push notifications, system notifications).
- Alarms and WorkManager: Scheduling background tasks using
AlarmManager and the WorkManager API.
- App Widgets: Building interactive widgets that can be added to the home screen.
8. Android Architecture Components
Key Topics:
- Model-View-ViewModel (MVVM): Introduction to MVVM architecture for better app structure and testing.
- LiveData and ViewModel: Using
LiveData for observing changes in data and ViewModel to separate UI-related data.
- Room Database: Advanced usage of Room for local data storage with a focus on relationships and transactions.
