LiveData
LiveData is a data holder used in Android development that allows apps to observe changes in data in real-time. Think of it as a subscription service — when the data updates, all registered observers (such as user interface components) are automatically notified and can respond accordingly. This helps keep the app's display consistent with its data without manual checks. LiveData is lifecycle-aware, meaning it respects the app's current state, preventing crashes or memory leaks. In essence, it simplifies dynamic data handling, ensuring the user interface remains synchronized with underlying data changes efficiently and safely.
