Sybase Unwired Platform now supports using a messaging channel to send change notifications from the server to the client device. Clients receive device notifications when a data change is detected for any of the MBOs in the synchronization group to which they are subscribed. By default, change notification is disabled. You can enable the change notification through setting properties in the synchronization group.
When the server detects changes in an MBO affecting a client device, and the synchronization group of the MBO has change detection enabled, the server will send a notification to client device through messaging channel. By default, a background synchronization downloads the changes for that synchronization group. The application can implement the onSynchronize callback method to monitor this condition, and either allow or disallow background synchronization.
