Push API

The Push API provides functionality for receiving push notifications from the Tizen push server. The push service is a client daemon that maintains a permanent connection between your device and the Tizen push server. Connection with push server is used to deliver push notifications to the application, and process the registration and deregistration requests.

To receive push notifications, follow the steps below:

  • Connecting to the push service
  • Registering your application, if the application has not been registered yet
  • Getting notification data

For more information on the Push features, see Push Guide.

To use Push features the application needs the permission to access the Tizen Push servers.

Service Limitation:

  • Size of a push message is limited: alertMessage up to 127 bytes, and appData (payload data) less than 1 KB.
  • Push service does not guarantee delivery and order of push messages.

Since: 3.0

A push service registration identifier.

    typedef DOMString PushRegistrationId;

Since: 3.0

1.2. PushRegistrationState

A push registration state.

    enum PushRegistrationState {"REGISTERED", "UNREGISTERED"};

Methods

register
Registers an application to the Tizen push server.

void register(PushRegisterSuccessCallback successCallback, optional ErrorCallback? errorCallback);
             

Since: 3.0

The ErrorCallback() is launched with these error types:

  • TimeoutError - If the operation timed out.
  • AbortError - If the operation cannot be finished properly.

The connect() method must be called before calling the register() method.

Privilege level: public

Privilege: http://tizen.org/privilege/push

Remark : In order to use the push messaging service, see Push Guide.

Parameters:

  • successCallback: The callback to be called when the registration request succeeds.
  • errorCallback [optional] [nullable]: The callback to be called when the registration request fails.

Exceptions:

  • WebAPIException
    • with error type TypeMismatchError, if any input parameter is not compatible with the expected type for that parameter.

    • with error type SecurityError, if the application does not have the privilege to call this method.

    • with error type InvalidStateError, if the application is not connected to the push service.

    • with error type AbortError, if the operation cannot be finished properly.

Code example:


 // Defines the error callback.
 function errorCallback (response) {
   console.log("The following error occurred: " +  response.name);
 }

 // Defines the registration success callback
 function registerSuccessCallback (id) {
   console.log("Registration succeeded with id: " + id);
 }

 // Defines the state change callback
 function stateChangeCallback (state) {
   console.log("The state is changed to: " + state);

   if (state == "UNREGISTERED") {
     // Requests application registration.
     tizen.push.register(registerSuccessCallback, errorCallback);
   }
 }

 // Defines the notification callback
 function notificationCallback (notification) {
   console.log("A notification arrives.");
 }

 // Connects to push service
 tizen.push.connect(stateChangeCallback, notificationCallback, errorCallback);
 

Output example:

 The state is changed to: UNREGISTERED
 Registration succeeded with id: 04a150867a50f48cb79695ac732cbe550b4a6782fffd23cbc14ba8dd5c5ab0025dad29a3e4ef5de8849b95b726bea7a6395c

PushRegistrationId getRegistrationId();
             

Since: 3.0

Privilege level: public

Privilege: http://tizen.org/privilege/push

Return value:

PushRegistrationId ID assigned by push service.

Exceptions:

  • WebAPIException
    • with error type SecurityError, if the application does not have the privilege to call this method.

    • with error type UnknownError, if any other error occurs.

Code example:


 var registrationId = tizen.push.getRegistrationId();
 if (registrationId != null) {
   console.log("The registration id: " + registrationId);
 }
 

Code example:


 // Defines the state change callback
 function stateChangeCallback (state) {

   var id = tizen.push.getRegisterationId();
   console.log("The registration ID: " + id);

 The registration ID: 04a150867a50f48cb79695ac732cbe550b4a6782fffd23cbc14ba8dd5c5ab0025dad29a3e4ef5de8849b95b726bea7a6395c
 
getUnreadNotifications
Requests to get unread push notifications. As a consequence, the PushNotificationCallback which was set using the connectService() method will be invoked to retrieve the notifications..

void getUnreadNotifications();
             

Since: 3.0

The connectService() method must be called to connect to Tizen push server and receive push notifications before calling the getUnreadNotifications() method. If connectService is not called, ServiceNotAvailableError occurs.
If any unread message exists, you will get unread push notification message through PushNotificationCallback of connectService(). For instance, if there are 10 unread messages, the PushNotificationCallback will be invoked 10 times.

If an application receives unread messages, the messages are removed from the system.

When an application registers with the push server to receive push notifications, the push server stores messages for the application until they are delivered. While the application is not running, messages cannot be delivered. This method allows retrieving such missed push messages. Once a missed push notification is retrieved the server deletes it from its database.

Privilege level: public

Privilege: http://tizen.org/privilege/push

Exceptions:

  • WebAPIException
    • with error type ServiceNotAvailableError, if the network is unreachable for some reason(e.g disconnected to the Tizen push server)

    • with error type SecurityError, if the application does not have the privilege to call this method.

    • with error type UnknownError, if any other error occurs.

Code example:


 // Defines the connect success callback
 function notificationCallback(message) {
     console.log("New push message : " + message.alertMessage + ", date : " + message.date + ", data : " + message.appData);
   }
 }

 // Requests for push service connection
 tizen.push.connectService(notificationCallback);
 tizen.push.getUnreadNotifications();
 

Code example:


 // Defines the state change callback
 function stateChangeCallback (state) {
   console.log("The state is changed to: " + state);

   if (state === "REGISTERED") {
     // Gets unread push notifications
      tizen.push.getUnreadNotifications();
   }
 }

 // Defines the notification callback
 function notificationCallback (notification) {
   console.log("A notification arrives.");
 }

 // Requests for push service connection
 tizen.push.connect(stateChangeCallback, notificationCallback);
 

Output example:

 The state is changed to: REGISTERED
 
getPushMessage
Gets push messages when the application is launched by the push service.

PushMessage? getPushMessage();
             

Since: 3.0

If the application is launched by the push service, the push service is connected when the application is launched. Therefore, you can get push messages without calling the connect() function.

If the application was not launched by the push service, this method returns null.

Privilege level: public

Privilege: http://tizen.org/privilege/push

Return value:

PushMessage The last message delivered from the push service or null.

Exceptions:

  • WebAPIException
    • with error type SecurityError, if the application does not have the privilege to call this method.

    • with error type AbortError, if the operation cannot be finished properly.

Code example:


 try {
   var message = tizen.push.getPushMessage();
   console.log('Message received from: ' + message.sender);
 } catch (err) {
   console.log('Exception - code: ' + err.name + ' message: ' + err.message);
 }
 

Output example:

 Message received from: xyz.AnotherApp
