What is an activity, service, view model, live data and jetpack compose

Question

Accepted Answer

Activity, service, view model, live data, and Jetpack Compose are key components in Android development.

Activity: Represents a single screen with a user interface. Example: MainActivity.
Service: Performs long-running operations in the background without a user interface. Example: MusicPlayerService.
View Model: Stores and manages UI-related data in a lifecycle-conscious way. Example: MainViewModel.
Live Data: Data holder class that is lifecycle-aware and ensures UI updates only when data changes. Example: LiveData.
Jetpack Compose: Modern Android UI toolkit for building native UIs using a declarative approach. Example: @Composable function.
