Notice: About Foreground Service Alert

According to Google’s Android Oreo policy, we are obligated to show the service status in the notification channel when the service is running in the background. You can go to settings to hide the alert and keep the service working.

If your device is Android 8.0/8.1 system, after you switch off the foreground service alert, you will still see Android system alert. If you are Android 7 or below users, this policy will not affect you.
