Answer 1

First, You need to define which server you will use to store user data (Firebase, Personal server.. etc).

Then you had multiple choices to SYNC user data with the server

Synchronization Service

You can use the power of WorkManager

to do the job for you. By storing every new diary object inside RoomDB by inserting it to the DB and after successful insertion you can SYNC your data with your server using WorkManager and delete the diary object after successful update.

OR

You can insert every single diary in RoomDB as a list of diaries after saving it, and while the app is launching you can SYNC this list of diaries with your server.
