Please help me write this Android Studio application using Java. I have it done, but it is currently using SQLite Open Helper, however we are supposed to use the 'Room Persistence Library'. You can either write it from scratch, or simply modify the current files to use Room instead.

You can get the project from here:

PLEASE ALSO POST THE CODE TO SHOW THE DIFFERENT FILES modified.

You may also post a link from where I can download the project instead. Thank You!
