What is the unique characteristic of Foreground Service in Android?

Foreground Service in Android is a service that runs with increased priority and must display a notification in the notification panel. Its unique characteristic is that the system cannot easily terminate such a service to free resources, even under low memory conditions, ensuring the continuous operation of an important process (e.g., playing music or location tracking). This distinguishes it from regular background services, which can be killed by the system without warning.
