What types of services have you used in your work?

In Android, I used the following types of services:

• Foreground Service — a service that runs in the foreground with a notification, for example, for playing music or tracking location.
• Background Service — a service that performs tasks in the background, such as data synchronization.
• IntentService — a service that handles asynchronous requests on a separate thread and automatically stops after completion.

An example of using a Foreground Service is a music player that continues playing even when the app is minimized, showing a notification in the status bar.
