## 1. Android에서 Service란 무엇인가요?

**답변**

Service는 사용자 인터페이스 없이 백그라운드에서 실행되는 Android 컴포넌트입니다. 파일 다운로드나 음악 재생과 같은 장시간 실행 작업을 수행할 수 있습니다. Manifest에 선언해야 합니다.

## 2. Started Service와 Bound Service의 차이점은 무엇인가요?

**답변**

Started Service는 startService()로 시작되며 시작한 컴포넌트와 독립적으로 백그라운드에서 계속 실행됩니다. Bound Service는 bindService()를 통해 하나 이상의 컴포넌트에 연결되며, 모든 클라이언트가 바인드 해제하면 자동으로 중지됩니다. 서비스는 Started와 Bound를 동시에 가질 수 있습니다.

## 3. Started Service를 시작하는 방법은 무엇인가요?

**답변**

startService(Intent) 또는 Android 8+ 용 startForegroundService(Intent)를 사용합니다. 서비스는 onStartCommand()를 수신하고 계속 실행됩니다. stopSelf()로 스스로 중지하거나 stopService()로 중지해야 합니다.
