Welcome to my Q&A. It’s Live, and it works best when people asks questions :). I don’t have all the answers, but I can often point you in the right direction.

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:
– Repository to Abstract Room’s API
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.
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:
3:00 Starting point for Source Code
3:50 Gradle and Res (Mostly copy Paste from the finished Repo here)
9:42 Project/Package Structure
12:05 Project Architecture Overview: Model-View-ViewModel
19:40 Room Entities
22:20 Room Data Access Object (DAO)
33:40 Room Database
37:28 LiveData (Android Architecture Components)
43:27 ListItemRepository (Repository to Abstract Room from ViewModels)
49:52 Activities and Views (This is mostly Copy and Paste, check old tutorial for help with building Layouts)
57:37 A simple Dagger 2 Set Up
1:07:28 ViewModel (Android Architecture Components)
1:17:33 ViewModelProvider.Factory (How to pass arguments to ViewModel Constructor)
1:24:00 Wiring up Views, ViewModels, and Observing the Data
1:34:45 Debugging and Demo
1:39:18 Working Demo!!!
1:41:00 Outro, Thanks, and Future Plans

Let’s Build a Room Database App Part 1 | Android Architecture Components Tutorial
Curious about how to build an App which uses Room Persistence Library, ViewModel, and LiveData, within the Context of a Model-View-ViewModel style Software Architecture?
In this Video, I outline the project we’ll be building in the next Video, and discuss the Architecture and APIs which we’ll use to get the job done.

Beginner Android Tutorial | 2.2 (MVP) Presenter and Contract | Calculator | 2016
In this video, I walk you through building our Contract Interface class as well as working on our Presenter. Apologies if this one is hard to follow. A lot of this stuff is fairly intuitive at first, and quite difficult to explain in a simple way. Feel free to ask questions!
