What is Android foreground service?

Foreground refers to the active apps which consume data and are currently running on the mobile . Background refers to the data used when the app is doing some activity in the background, which is not active right now.

Foreground services show a status bar notification, so that users are actively aware that your app is performing a task in the foreground and is consuming system resources. The notification cannot be dismissed unless the service is either stopped or removed from the foreground.

Foreground syncs can be very helpful for apps that need to constantly sync data . They ensure that important data is always up-to-date, regardless of whether or not you’re using the app. Foreground syncing also helps preserve battery life, since it allows apps to run in the background without using a lot of power.

Foreground services are an advanced Android concept which allows you to display notifications to your users when running long lived background tasks . The notification acts like any other notification, however it cannot be removed by the user and lives for the duration of the service.
