How to know if Unity Application is minimised {Mobile Devices}

Hey, I’m working on a project in which I have set notification if player forgot to set item to craft — but facing issue to determine if the app minimised. I was using OnApplicationPause, but there is an issue, It’s also called if ads are running or if I check achievement{google play}. So I want to know if there is a better way to do this?

private void OnApplicationPause (bool paused) { if (paused) StopStuff(); else DoStuff(); }
