Android Implementation notification bar messages

First, the principle
There are two kinds of message push, one is that the client can search the message directly to the server, get the message if new message is found, and the server sends a message to the client, that is, when there is an informational message, the server sends a message to the client.

Second, Step (code)

Note: Notification//is a specific status bar object, set icon, text, sound, and so on.
Notificationmangager//status bar notifies the management class, is responsible for sending messages, cleaning up messages.
