how to insert date time whenever insert/ update called in realm

[Syed Hassan]

I want to synchronize the android application with server. In Server i have maintained last update date through trigger as it uses SQL server but my android application uses Realm so how can i set current date time in a field whenever any row is inserted or updated. Is there any listener which calls whenever commitTransaction occurs? if yes then i can manually set updated date time on every insert and update. Any suggestion would be highly appreciated.

Hey Syed,

You can add an change listener manually, and get notifications. See https://realm.io/docs/java/latest/#notifications for details. Currently, we don't offer fine-grained notifications (we have an open issue: https://github.com/realm/realm-java/issues/989) so you can only get notified that something has changed (object added, removed or updated).

Best,
Kenneth

Hey Syed,

The method Realm.createOrUpdate() might be what you're looking for.
