Talk: RxJava in Baby Steps

October 31, 2017 by Annyce Davis

Reactive Programming with RxJava has widely been adopted by both backend services and Android applications alike. Yet, the steep learning curve leaves many developers hesitant about adding it to their own Software tool belt. I was one such developer. Over the past two years, I’ve watched countless videos, read numerous blog posts and attended several conference talks on the subject. Yet, I often left each experience feeling only slightly more knowledgeable, but not quite empowered to start using RxJava in my apps. That’s not going to happen in this talk!

We cover the bare minimum concepts you need to grok, in order to start using RxJava today. In particular, we focus on:

  • The 3 O’s: Observable, Observer and Operator

  • Understanding those Marble Diagrams

Reactive Programming is not going away any time soon. It’s a powerful way to create asynchronous, event-based applications. It allows developers the ability to craft applications that can easily combine multiple network calls, gracefully handle failures, all while providing a snappy user experience.

August 29, 2017 by Annyce Davis

Over the past few months my team has been steadily moving our code over to Kotlin. It’s been a joy to get to work with such a succinct, yet expressive language. However, I have spent needless hours attempting to debug issues in my application that were all solved with the addition of this one thing: @JvmSuppressWildcards.

Using RxBinding with Kotlin and RxJava2

July 23, 2017 by Annyce Davis

RxBinding provides RxJava binding APIs for Android User Interface (UI) widgets. This allows us to easily translate Android UI events into Observable streams. Let’s look at a simple example of this: we’re going to consider how to execute an asynchronous network request from a Button click event.
