How do I detect application notification permissions?

In general, there is no notification management in Api 19, which is enabled by default. Api 19 — 24 adds notification management functionality, but does not open the interface to check whether notifications are enabled, so developers can only use reflection to obtain permission values. Above Api 24, NotificationManager provides the areNotificationsEnabled () method to detect notification permissions. In 24.1.0, areNotificationsEnabled () is enabled. Values below 19 return true by default,19-24 return the corresponding reflection value, and above 24 use native NotificationManager.

Special case is part of the domestic machine, joined the notification related custom function, the developer is out of control or detection, completely blind. Such as whether the following notification is displayed in the status bar administration.
