- Q1. What is service?
- Ans.
A service is a component that runs in the background to perform long-running operations without a user interface.
Services can be used to handle network transactions, play music, perform file I/O, etc.
They can run in the same process as the main application or in a separate process.
Services can be started or bound to by other components in the application.
- Q2. Explain Service Types
- Ans.
Service types in Android include started services, bound services, and foreground services.
Started services are initiated with startService() and run independently of the calling component.
Bound services are initiated with bindService() and allow components to interact with the service.
Foreground services have a notification to indicate that they are running in the foreground.
