Fields and helpers for accessing reminders for an event. Each row of this table represents a single reminder for an event. Calling[query(android.content.ContentResolver, long, java.lang.String[])](https://developer.android.com/reference/android/provider/CalendarContract.Reminders#query(android.content.ContentResolver,%20long,%20java.lang.String[]))will return a list of reminders for the event with the given eventId. Both apps and sync adapters may write to this table. There are three writable fields and all of them must be included when inserting a new reminder. They are:
- [CalendarContract.RemindersColumns.EVENT_ID](https://developer.android.com/reference/android/provider/CalendarContract.RemindersColumns#EVENT_ID)
- [CalendarContract.RemindersColumns.MINUTES](https://developer.android.com/reference/android/provider/CalendarContract.RemindersColumns#MINUTES)
