Which is the difference between Notification.build() and NotificationCompat.Build()

[ComptonAlvaro]

In the documentation, I have seen that to create a notification is used Notification.Build() but in another examples it is used NotificationCompat.Build().

In this post in StackOverflow they told about some versiones of both methods are deprecated.

So I would like to know which is the actual best way to create a notification.

Thanks.
