Question 1

What is a Service in Android?

Accepted Answer

A Service is an Android component that runs in the background without a user interface. It allows performing long-running operations like downloading files or playing music. It must be declared in the Manifest.

Question 2

What is the difference between a Started Service and a Bound Service?

Accepted Answer

A Started Service is launched with startService() and continues running in the background independently of the component that started it. A Bound Service is connected to one or more components via bindService(), and stops automatically when all clients unbind. A service can be both Started and Bound.

Question 3

How to start a Started Service?

Accepted Answer

Use startService(Intent) or startForegroundService(Intent) for Android 8+. The service receives onStartCommand() and continues running. It must stop itself with stopSelf() or be stopped with stopService().
