Service running but threads are stopped

Question

I have created a foreground service which spawns some repeating threads in ScheduledThreadPoolExecutor.

I want to keep the service and its threads running. I only stop threads in the onDestroy method of service.

When I close the app from recents the foreground notification remains as I desire. But the problem is: In Device1 threads are stopped while in Device2 they keep running.

Device1: A miui ROM smartphone Device2: A google ROM smartphone

Is there any way I can keep the threads running? I have checked that the onDestroy method is not being called. I have enabled autostart in MIUI device.

Answer 1

Seems like this is device issue. In the MIUI device I have tested multiple times, sometimes threads keep running while in some other case they don't.
