Talk: RxJava in Baby Steps

by

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
  • The most common Operators: map(), flatMap(), and filter()
  • 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. I want everyone to feel comfortable with the basic concepts of RxJava. Today can be your first step…

Talk: First Do No Harm

by

Developing Android applications is a powerful way to connect people with the information they need the most. Apps are for living your life: daily commutes, traveling abroad, communicating with family, and much more! This places the responsibility of engineering top-notch software squarely in the laps of us developers. Unlike doctors, we were not required to take an oath or pledge when becoming Android Developers. However, we can still learn much from the principles behind the phrase, “First, do no harm.” In this talk, we will discuss over a dozen tools that are at your disposal as a developer which can enable you to provide high quality applications to your users. Thus allowing you to first, do no harm!

This talk covers:

  • Resources for Study
  • Preventative Techniques
  • Diagnostic Tools

Talk: Develop Maintainable Apps

by

Great Android apps only include what’s needed to achieve the goals of the product, not enhance the resume of the developer. What’s more, the more maintainable an application is, the more likely it will have increased user satisfaction and decreased time to market.

This talk covers:

  • Choosing your 3rd Party Components Wisely
  • Keeping your Code Simple
  • Using Static Code Analysis Tools
  • Writing Unit Tests
