You can use messaging functionalities, such as SMS, MMS, and email.

This feature is supported in mobile applications only.

The messaging process used in HTML5 involves Uniform Resource Identifiers (URIs), which form values of attributes, such as tel, mailto, and sms. These attributes invoke external services which then perform the messaging tasks. The Messaging API minimizes your coding efforts by providing one-step capabilities to perform all high-level messaging-related operations.

The main features of the Messaging API include:


To use the Messaging API, the application has to request permission by adding the following privileges to the config.xml file:

<tizen:privilege name=""/>
<tizen:privilege name=""/>

Creating and Sending Messages

You can create a message by using the Message object constructor, and you can set the message attributes and parameters using a MessageInit object (for example, you can set the message service type - SMS, MMS or email - by using the type parameter).

Note The system assigns a unique read-only message ID to each message the first time it is processed, such as when sending it or creating a draft message for it.

To create and send messages:

  1. Retrieve the messaging service using the getMessageServices() method. The first parameter specifies the type of the messaging service to retrieve. There are 3 possible types: "messaging.sms", "messaging.mms" and "". In the following example, the SMS service is retrieved.

    function errorCallback(error) {
        console.log( + ': ' + error.message);
    tizen.messaging.getMessageServices('messaging.sms', serviceListCB, errorCallback);
  2. In the success callback of the getMessageServices() method, use the Message interface to define the content and attributes of the message, and then send the message using the sendMessage() method of the MessageService interface. The sendMessage() method requires both success and error event handlers. Depending on the result of the sending operation, the message is moved to the device's Sent Items or Drafts folder, and additionally stored in the message storage database.

    If the message is not ready to be sent yet, save the message draft using the addDraftMessage() method of the MessageStorage interface.

    function onAddSuccess() {
        console.log('Successfully added');
    function serviceListCB(services) {
        /* Define SMS message */
        var msg = new tizen.Message('messaging.sms', {
            plainBody: 'I will arrive in 10 minutes.',
            to: ['+34666666666', '+34888888888']
        var msgReady = true;
        if (msgReady) {
            /* Send SMS message */
            services[0].sendMessage(msg, messageSent, errorCallback);
        } else {
            /* Save a draft */
            services[0].messageStorage.addDraftMessage(msg, onAddSuccess, errorCallback);

    If sending MMS or email messages with attachments, add the attachments as an array of MessageAttachment objects with the file path and the MIME type (image/png, text/pdf, or text/html) defined for each object.

    Assign the array to the attachments attribute of the Message object.

    var msg = new tizen.Message('');
    msg.attachments = [new tizen.MessageAttachment('images/myimage.png', 'image/png'),
                       new tizen.MessageAttachment('docs/mydoc.pdf', 'text/pdf')];
  3. Define the message sending success callback that is called if the message is sent successfully. (For email, that means that the message is sent to the email delivery system, not to the final recipient of the message.)

    For messaging technologies, such as SMS, where the message is sent individually to every message recipient, the success callback must be invoked individually for each recipient.

    function messageSent(recipients) {
        for (var i = 0; i < recipients.length; i++) {
            console.log('The SMS has been sent to ' + recipients[i]);

    Defining a sending error callback allows you to handle all possible errors and exceptions that can occur causing the message delivery to fail.

Selecting the SIM Card for Sending Messages

If there are multiple SIM cards in the device, by default the system determines which one is used to send a message. You can also specify the SIM card when sending an SMS.

To add the dual SIM feature to your messaging application, you must learn to retrieve information on available SIM cards and select the SIM card to send SMS and MMS messages:

  1. To check how many SIM cards are available, call the getCount() method of the SystemInfo interface.

    var count = tizen.systeminfo.getCount('SIM');
    if (count > 1) {
        console.log('Dual SIM is supported');
  2. To retrieve additional information on the available SIM cards, use the getPropertyValueArray() method of the SystemInfo interface:
    function getPropertySuccess(sims) {
        for (var i = 0; i < sims.length; i++) {
            console.log('SIM' + (i+1) + ' - ' + sims[i].msisdn + ' (' + sims[i].operatorName + ') ' + sims[i].state);
    tizen.systeminfo.getPropertyValueArray('SIM', getPropertySuccess);

    The information can be presented to the user to let them select the SIM card they want.

  3. To send the message using the second SIM card, call the sendMessage() method of the MessageService interface specifying the SIM index as 2:
    function sendSuccess() {
        console.log('Message has been sent');
    function serviceSuccess(messageService) {
        message = new Message(messageService.type, {
            to: ['0001'],
            plainBody: 'Surprise!'
        /* SIM is selected (first SIM - 1, second SIM - 2) */
        messageService.sendMessage(message, sendSuccess, null, 2);
    tizen.messaging.getMessageServices('messaging.sms', serviceSuccess);

Managing Messages

You can find, update, and delete stored messages with methods provided by the MessageStorage interface: findMessages(), updateMessages(), and removeMessages(). The interface allows you to manage message storages.

To work with messages in the message store:

  1. Retrieve messages whose sender is "me" from the message storage using the findMessages() method of the MessageStorage interface .

    When searching for messages, you can create attribute filters, attribute range filters, and composite filters based on specific filter attributes. You can also sort the search results.

    var emailService;
    function serviceListCB(services) {
        emailService = services[0];
        /* Set the attribute filter */
        var filter = new tizen.AttributeFilter('from', 'CONTAINS', 'me');
        emailService.messageStorage.findMessages(filter, messageArrayCB);
    tizen.messaging.getMessageServices('', serviceListCB);

    The findMessages() method returns an array of Message objects as the search result.

    The search result does not contain the actual bodies of the messages. To load a message body, call the loadMessageBody() method of the MessageService interface.

  2. To update a message in the message storage, use the updateMessages() method. The method uses an array of Message objects found previously by the findMessages() method as a parameter.

    In the following example, the isRead attribute of the first Message object in the given array is updated to true.

    function successCallback() {
    function messageArrayCB(messages) {
        messages[0].isRead = true;
        emailService.messageStorage.updateMessages(messages, successCallback);
  3. To delete a message from the message storage, use the removeMessages() method:

    function messageArrayCB(messages) {
        emailService.messagingStorage.removeMessages(messages, successCallback);

Finding Folders

To find message folders, use the findFolders() method of the MessageStorage interface:

  1. To retrieve the messaging service, use the getMessageServices() method of the Messaging interface:

    var service;
    function serviceListCB(services) {
        console.log('Found ' + services.length + ' email services');
        service = services[0];
    tizen.messaging.getMessageServices('', serviceListCB);
  2. Define a success handler implementing the MessageFolderArraySuccessCallback interface, and optionally an error handler too:

    function onFindFolders(folders) {
        console.log(folders.length + ' folder(s) found.');
        for (var i = 0; i < folders.length; i++) {
            console.log('Folder ' + (i + 1) + ': ' + folders[i].name);
    function onFindFoldersFail(error) {
        console.log('Error occurred:  ' +;
  3. Define a filter (for attributes supported by the message folder filter, see Messaging Filter Attributes):

    var filter = new tizen.AttributeFilter('serviceId', 'EXACTLY',;
  4. To get all message folders, use the findFolders() method of the MessageStorage interface:

    service.messageStorage.findFolders(filter, onFindFolders, onFindFoldersFail);

Synchronizing with the Server

To keep your email service accounts up-to-date, synchronize them with their respective external servers, such as Gmail and Microsoft Exchange, with the sync() method. You can also synchronize a single folder, such as the Inbox, with the syncFolder() method. You can specify the maximum number of messages that can be retrieved in each folder.

It is possible that an email message is accessible through the Message object, but its full body or attachment has not been downloaded yet. You can load email messages and attachments from the email service with the loadMessageBody() and loadMessageAttachment() methods of the MessageService interface.

To load email messages and attachments and synchronize email:

  1. Retrieve the messaging service using the getMessageServices() method.

    tizen.messaging.getMessageServices('', serviceListCB, errorCallback);
  2. Search for all email messages with attachments using the findMessages() method of the MessageStorage interface:

    service.messageStorage.findMessages(new tizen.AttributeFilter('hasAttachment', 'EXACTLY', true),
  3. To load a message body, use the loadMessageBody() method of the MessageService interface:

    /* Success callback for the search operation */
    function messageQueryCallback(messages) {
        for (var i = 0; i < messages.length; i++) {
            var message = messages[i];
            if (!message.body.loaded) {
                tizen.messaging.loadMessageBody(message, successCallback, errorCallback);
  4. To download the message attachments, use the loadMessageAttachment() method with an array of attachments (with valid file paths) as a parameter:

                tizen.messaging.loadMessageAttachment(message.attachments[0], successCallback,
  5. To synchronize email with an external server:

    1. To synchronize all account folders, use the sync() method:

      /* Synchronize the folders in the success event handler */
      function servicesListSuccessCB(services) {
          services[0].sync(serviceSyncedCB, null, 30);
      /* Get the email service */
      tizen.messaging.getMessageServices('', servicesListSuccessCB);
    2. To synchronize a specific folder, use the syncFolder() method. In the following example, only folders containing "INBOX" in their name are synchronized.
      var emailService; /* Assume email service is initialized */
      function serviceCallback(services) {
          emailService = services[0];
      /* Synchronize in the search success event handler */
      function folderQueryCallback(folders) {
          for (var i = 0; i < folders.length; i++) {
              if (folders[i].type === 'INBOX') {
                  emailService.syncFolder(folders[i], folderSyncedCB, null, 30);
      /* Get the email service */
      tizen.messaging.getMessageServices('', serviceCallback, errorCallback);
      /* Search for specific folders */
      var filter = new tizen.AttributeFilter('serviceId', 'EXISTS');
      emailService.messageStorage.findFolders(filter, folderQueryCallback));

Receiving Notifications on Message Storage Changes

You can register event listeners to monitor changes in the message storage, a particular conversation, or a particular message folder.

The addMessagesChangeListener(), addConversationsChangeListener(), and addFoldersChangeListener() methods of the MessageStorage interface register an event listener, which starts asynchronously once the method returns the subscription identifier for the listener. You can use the MessagesChangeCallback, MessageConversationsChangeCallback, and MessageFoldersChangeCallback interfaces to define listener event handlers for receiving notifications about the changes.

To receive notifications when messages and message folders are added, updated, or removed:

  1. Define the needed variable:

    /* Watch identifier */
    var watchId;
  2. Define the event handlers for different notifications by implementing the MessagesChangeCallback listener interface:

    var messageChangeCallback = {
        /* When messages are updated */
        messagesupdated: function(messages) {
            console.log(messages.length + ' message(s) updated');
        /* When messages are added */
        messagesadded: function(messages) {
            console.log(messages.length + ' message(s) added');
        /* When messages are deleted */
        messagesremoved: function(messages) {
            console.log(messages.length + ' message(s) removed');
  3. Register the listener to use the defined event handlers:
    watchId = msgService.messageStorage.addMessagesChangeListener(messageChangeCallback);
  4. To stop receiving the notifications, use the removeChangeListener() method of the MessageStorage interface:

NoteTo provide notifications for changes in specific conversations or message folders, use the applicable methods and event handlers similarly as above.
