What is Service in Android?

A service is a component that runs in the background. It is used to play music, handle network transaction, etc.

In Android, a service is a component that runs in the background to perform long-running operations or to handle tasks without a user interface. Services do not have a visual interface, and they run independently of the user interface of an application.

There are two main types of services in Android:

1. Started Services: These services are explicitly started and stopped by an application. They continue to run in the background even if the component that started them is destroyed. They are typically used for tasks that need to run in the background, such as downloading a file or playing music.
2. Bound Services: These services provide a client-server interface that allows components (such as activities) to bind to the service, send requests, and receive responses. Bound services are useful for communication between different parts of an application or between different applications.

Services play a crucial role in the Android system for managing background tasks, handling network operations, and providing functionality that should continue running even when the application is not in the foreground.
