Hi everyone
I have a calendar sync project, I wonder how can I get "dirty" events (change since last synced) and get time when it change. There are many data columns in Event table but I don't know which columns has "update" flag. I watch data in these columns Events.LAST_SYNCED is always 0, Events.DIRTY is always 1, Events.DELETED is always 0,..... no thing change when I make change event in native calendar app. Does anyone have experience on this

Thank for your reading

Does anyone know? I reseach it for a week now, still no result....
