GymLog Application

All of the associated videos are linked in this Panopto folder. It may be necessary to log in to your CSUMB account to view the videos. The goal of this project is to work through all the steps necessary to create an app that uses the Room database wrapper for persistence and that allows users to log in. If I am feeling brave I will add in a recycler view too.

Overview and plan

intro video This is the overall view of the final product. Once I get the login screen setup and working, including the logout features, I will record this video. Anything afer this (editing logs, more user info, etc. Will be shown in their respective video).

Video 01: Setup

   • Android Room Dependency
2. create the POJO entity objects
   • for now just a GymLog
3. Create the database interface
4. Create the GymLog DAO
5. Make the repository
   • Requires lots of lambdas and auto-completes

Bugs to fix

   • Issue is with asynch so adding a recycler will fix it...
