Tizen Native API  5.5

The Push API provides functions to receive push notifications.

Required Header

#include <push-service.h>

Overview

The Push API allows your application to receive push notifications from a push server. The push service is a client daemon that maintains a permanent connection between your device and the push server, in order to process your registration/deregistration requests and deliver push notifications to your application. If the application is connected, the push service passes the notification data over the connection. Otherwise, the push service posts a UI notification with the data. It will be delivered when a user launches the application by selecting the posting.

To receive push notifications, you need to follow the steps below:

  • Connecting to the push service
  • Registering your application
  • Getting notification data

Push notification helps your application server send data to the application on devices over an IP network even if the application is not running. Push notification may reduce battery consumption over other applications keeping its own connection to its remote application server.

Service Limitation

  • Payload of a push message is limited to 4096 bytes.
  • Administrative permission is needed for your application and server to use the push service.
  • Push service does not guarantee delivery and order of push messages.
  • A device should have a valid IMEI number.

Defines

#define APP_CONTROL_DATA_PUSH_LAUNCH_TYPE   "http://tizen.org/appcontrol/data/push/launch_type"
 This is key string for getting extra data of App Control response.

Define Documentation

#define APP_CONTROL_DATA_PUSH_LAUNCH_TYPE   "http://tizen.org/appcontrol/data/push/launch_type"

This is key string for getting extra data of App Control response.

Since :
3.0
Remarks:
Your application could be launched in the background by push service.
If you want to know what push operation makes your application wake up, use app_control_get_extra_data() with below key.
In the case that your application is launched by push notification with "LAUNCH" option, you can see a value, "notification" in App Control callback.
On the other hand, when the state of registration changed, you can find the other value, "registration_change".

See also:
push_service_deregister()

Requests unread notification messages to the push server.

When the app wants to receive messages that arrived before it launched, this
method should be called. Upon receiving this request, the daemon sends messages
stored in its DB to the app. The notify_callback() method assigned in push_service_connect()
will be called when these messages arrive. No need to call this method multiple
times to receive multiple messages. This method does NOT guarantee order and
reliability of notification messages.

Since :
2.3.1
Remarks:
This method is preferred to push_service_get_unread_notification().
Parameters:
[in]connectionThe connection handle to the push service
Returns:
0 on success, otherwise a negative error value
Return values:
