Data Synchronization

You can synchronize device data, such as contacts and calendar events, with the OMA DS server using the OMA DS (Data Synchronization) 1.2 protocol.

This feature is supported in mobile applications only.

The main features of the Data Synchronization API include:

  • Creating a sync profile

    You can create a profile, define the profile name, and provide other profile and operation information using the applicable interfaces.

    Tizen sets a limitation on the number of supported OMA DS profiles on the device. Before creating a new profile, you must check whether sync profile slots are available.

  • Retrieving synchronization process information

    After starting the synchronization process, you can monitor the progress of the operation.

As a prerequisite to synchronizing your device data with the server, you must create an OMA DS server account.


To use the Data Synchronization API, the application has to request permission by adding the following privilege to the config.xml file:

<tizen:privilege name=""/>

Creating a Sync Profile

To create a sync profile:

  1. Check whether there are available profile slots on the device using the getProfilesNum() and getMaxProfilesNum() methods of the DataSynchronizationManager interface:

    var numMaxProfiles = tizen.datasync.getMaxProfilesNum();
    var numProfiles = tizen.datasync.getProfilesNum();
  2. Create a sync profile. Use the SyncInfo, SyncServiceInfo, and SyncProfileInfo interfaces to provide sync profile and operation information:

    if ((numMaxProfiles <= 0) || (numProfiles < numMaxProfiles)) {
        var syncInfo = new tizen.SyncInfo('', 'myId', 'myPassword', 'MANUAL', 'TWO_WAY');
        var contactInfo = new tizen.SyncServiceInfo(true, 'CONTACT', 'serverContact');
        var eventInfo = new tizen.SyncServiceInfo(true, 'EVENT', 'serverEvent');
        var serviceInfo = [contactInfo, eventInfo];
        var profile = new tizen.SyncProfileInfo('MyProfile', syncInfo, serviceInfo);
  3. To be able to use the created profile, add it to your device using the add() method of the DataSynchronizationManager interface:

        var profileId = profile.profileId;

Starting and Monitoring Data Synchronization

After starting the synchronization process using the startSync() method of the DataSynchronizationManager interface, you can monitor the progress of the operation. Use the SyncProgressCallback interface to define listeners for receiving notifications. After the synchronization is completed, you can retrieve statistics using the getLastSyncStatistics() method.

To start and monitor the data synchronization process:

  1. Define the event handlers for the notifications using the SyncProgressCallback listener interface:

    var syncCallback = {
        onprogress: function(profileId, serviceType, isFromServer, totalPerType, syncedPerType) {
            console.log('Total: ' + totalPerType + ', synced: ' + syncedPerType + ' for the sync type: ' + serviceType);
        onfailed: function(profileId, error) {
            console.log('Failed with id: ' + profileId + ', error name: ' +;
  2. Start the sync operation using the startSync() method, with the corresponding listener as a parameter:

    tizen.datasync.startSync(profileId, syncCallback);
