This method should only be used by applications that replace the platform-wide management of audio settings or the main telephony application.

From N onward, ringer mode adjustments that would toggle Do Not Disturb are not allowed unless the app has been granted Do Not Disturb Access. See NotificationManager#isNotificationPolicyAccessGranted().
