Let’s Build a Room Database App | Room, ViewModel, LiveData, Dagger 2, MVVM Architecture

Please Note: This is meant to be an Intermediate Tutorial, which follows my Beginner Let’s build a RecyclerView App Tutorial. All of the stuff we copy/paste, and how to build Material Design Layouts, is in that tutorial:

Welcome to my Tutorial on Android Architecture Components, including Room Persistence Library, ViewModel, and LiveData. In this tutorial I’ve done my best to emply the following concepts in the creation of a simple Note-Taking Application:
– Model-View-ViewModel Architecture for the Front End/UI/Presentation Layer
– ViewModel from A.A.C.
– LiveData from A.A.C.

– Repository to Abstract Room’s API
– A Simplified Dagger 2 setup (we don’t discuss this much as D2 warrants some fairly length explanation I don’t have time for here)

The Code in this tutorial is based off of my 2017 RecyclerView App Tutorial. If you are a Beginner, or you are curious about building the View itself, you’ll want to get through that tutorial first. This is an intermediate tutorial, and I don’t stop to explain the basics of Software Architecture or the Android Platform here so much.

Main Project Repository (finished Demo for reference/copy paste)

Starting Point, based on RecyclerView Tutorial’s UI:

Android Architecture Components Samples (Please check these out, I mostly learned Room from them!)

Martin Fowler on MVVM (a.k.a. Presentation Model a.k.a. Application Model); gives some history and insight on the pattern:

If at any point in this Video I come off as being disrespectful (particularly when I’m complaining about MVVM and stuff like that), please forgive me. Part of my content is sharing my expereince as a learner, and it’s never my intention to offend anyone.
