What is a foreground service Android?

Foreground services display a notification in the status bar so that users are aware that your program is running in the foreground and consuming system resources. 

Unless the service is terminated or removed from the forefront, the notice cannot be dismissed.

For short-running foreground services, devices running Android 12 (API level 31) or higher provide a simplified experience. The system waits 10 seconds on these devices before displaying the notice associated with a foreground service. There are a few exceptions; some services will always display a notification right away.

The following are some examples of apps that take advantage of foreground services:

  1. A music player app that uses a foreground service to play music. The notification could display the currently playing song.
  2. After getting authorization from the user, a fitness app records a user’s run in a foreground service. The distance traveled by the user during the current fitness session may be displayed in the notice.
