What are the time constraints of the service?

Android services have time execution limits, especially in recent OS versions, to save resources and battery.

• Foreground Service (service with notification) can run without time restrictions.
• Background Service (background service) from Android 8.0 (Oreo) and above is limited: if the service runs in the background without transitioning to foreground, the OS may stop it after a few minutes (usually around 5 minutes).
• For long-running tasks, it is recommended to use WorkManager or JobScheduler, which manage task execution considering system constraints.

Thus, time restrictions depend on the type of service and Android version, but generally, background services are not recommended to run for a long time without being moved to foreground.
