Android Developer Live Q&A for Beginner and Intermediate Developers – Ep. 18

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.

Happy to discuss:
Android Framework and APIs (RecyclerView, Fragment…)
Software Architecture (Clean, MVP, MVC, Design Patterns, SOLID Principles…)
Test Driven Development (Unit Testing, Problem Statements…)
Online Portfolio Building, Job Application and Interview Tips
Interesting off topic discussion

How To Learn Android Effectively | What to Focus on between Projects, Courses, and Books

This Video was cut from Livestream Q&A Ep. 14.

In this Video, I address different ways to approach learning Android. I discuss my own personal experience, as well as some practical tips on Cognition and Motivation (these are implicitly tied to each other, as interest levels are a major factor in determining whether material enters into memory or not).

RoadMap for Junior Android Developers – APIs, App Ideas, Resources, and Portfolio Building

In this Video I talk about how to go from a Beginner Android Developer, to a “Junior Android Developer”. According to my subjective definition, a Junior Developer should have at least one small-medium size Application.

I talk about how to go about deciding on, designing, and building your “Flagship” App, as well as an overview of the Industry Standard APIs which you’ll want to learn to improve your job prospects.

Towards the end, I discuss some resources to help you build your App, and how to build a Portfolio to help you get hired.

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:
https://www.youtube.com/watch?v=RfTJ2SePYaU&list=PLEVlop6sMHCohK2XryPUqhglysv1Xxakt

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.

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.

What are Design Patterns, and how do I use them? w/ Simple Language and Examples

Design Patterns are in my experience, the most poorly explained yet important topic in Software Architecture and Development. In this Video, I attempt to explain them with lots of Practical Examples and as little Jargon as possible. I talk about what Design patterns are, and how they can help you write better Apps. At the end, I give you a simple Metaphor to use to understand how they work.

Would you like to ask me questions directly, about anything Android, general to specific? If so, consider joining me one of these Sundays at 9:00AM PDT (GMT -7), for my Live Android Developer Q&A.
