How Android Began
12:10–1:00 PM • Chet Haase

The book "Androids: the Team That Built the Android Operating System" tries to answer the question: Why did Android succeed? Along the way, it explores the stories of the people that created the OS.

This session will do likewise, sharing some of the stories of that early team and culture and trying to give some sense of how, against all odds, Android managed to survive to where it is now available on over 3 billion devices today.

Automating Android Workflows with Github Actions
1:10–1:50 PM • Ubiratan Soares

When talking about CI/CD products, Github Actions is the new kid on block. It has been attracting a lot of attention from Engineers given its seamless integration with Github and is not surprising that it has been quickly adopted both at open-source projects and private-source projects, with Android being no exception on that!

In this talk we'll review the fundamentals of Github Actions as a CI/CD platform and learn how to make the most of it when designing and implementing automations for Android projects. We'll learn about particularities and limitations we can find when moving a big Android project over Github Actions and review some of the common solutions we have around for Android-specific use cases.

Demystify and Optimize Your Android Gradle Builds
2:00–2:40 PM • Nate Ebel

Gradle, and the Android Gradle Plugin, are the backbone of most Android projects today. They are also the source of much frustration for dev teams wishing their builds were faster or easier to work with.

This talk aims to demystify your Android build by helping you understand how Gradle works, what happens when you build your project, and how to start optimizing your build for increased developer productivity.

During this talk, we’ll focus on a few key areas including

  • The difference between Gradle and Android Gradle Plugin
  • What happens when you run a Gradle task
  • How to investigate your project’s build performance
  • Performance optimizations

By the end of the talk, you should better understand what happens when you build your Android app, and be equipped to start optimizing your builds for faster builds and happier developers.

Practical tips for CI/CD success for Android
2:00–2:40 PM • Zan Markan

Android teams often have to build and maintain their own CI/CD pipelines. This at first seems straightforward to implement and maintain. Yet it can often quickly become a tedious time sink and a source of universal frustration on many teams.

From flaky builds, to long running builds, to flaky long running builds, the sources of frustration are endless. With the goal to ship more and faster as well as to compete in an ever changing industry, we can (and must) do better.

This talk will cover best practices for performance, stability, security, and maintainability of CI/CD pipelines with a focus on developing for Android, each supported with practical examples and counterexamples.

From 0 to 98: Speed up your Testing with DaggerMock and Live Kaspresso
4:30–5:10 PM • Nick DiPatri

Untested code gets you on the road, but it will eventually slow you down. The prototype-to-production pipeline doesn’t always have the luxury of test-driven development. As a result, some production code has very low unit test coverage.

In this talk, you’ll learn how to use the new Espresso/UI-Automator based Kaspresso in unique ways to quickly stand up live, automated integration tests and keep production code reliably moving forward while your pit crew slowly builds up unit test coverage to 98 percent. You’ll learn how to use DaggerMock to migrate most of these live tests over time to more reliable mock integration tests. This talk will include a live demonstration, so fasten your seatbelts!

Xcode: Build Time Optimisation
1:30–1:50 PM • Mahesh De Silva

Building an Xcode project can be an unpleasant experience sometimes. Most of us have prior experience in wasting our precious deep-work hours because Xcode has no chill and takes its own time to rebuild everything repeatedly, even for the smallest of changes.

In this talk, I try to talk about different options Xcode provides us out of the box that helps to reduce heavy build times, along with a discussion of other factors that could contribute to slow compilation times. I'll also talk about a few examples of how some of the Tech companies out there tackle this issue.

SwiftUI.View: Codable - Transforming SwiftUI to JSON (and vice-versa) for a fully backend driven UI
2:00–2:40 PM • Florian Harr

Apple introduced Swift UI during WWDC2019 to gives us a way to codify our layout. But it doesn't only stop here - as a first-class citizen in Swift, we can make our SwiftUI Views conform to Codable to encode and decode our views representing SwiftUI in pure JSON.

Join me in this talk to see how you can codify your layout and benefit from an ultra-flexible UI where even full UIs can be dynamically injected.

XOXO for Declarative UI: The similarities between a tic-tac-toe board written in 3 declarative frameworks
2:00–2:40 PM • Sweety Bertilla, Dheeraj Neelam, Justin Thomas

There’s a rise in the number of libraries that encourage a “declarative” over “imperative” approach to creating UI. Every platform has at least one such library. Not only do these libraries offer a new way of thinking about programming, collectively they share a lot of similarities, regardless of the platform.

We know the rising popularity of declarative UI in Android with Jetpack Compose and iOS with Swift UI, but declarative UI has been used for quite some time on the web in React. We frequently hear people comment on the syntactic similarities between React and SwiftUI. In this presentation, Chris, Dheeru and Sweety would show a quick comparison of these three declarative UIs using a simple game app of tic tac toe.

Kotlin Multiplatform Library Development
2:50–3:30 PM • Kevin Galligan

Kotlin Multiplatform is maturing. There are a number of good libraries available, but to really shine, we'll need a few keystone libraries to emerge, and the door is wide open for a wave of specialized libraries. Less in the public view, some larger orgs are developing and publishing private KMP libraries internally, which presents its own set of issues. This talk is an update and refinement of a talk I gave in 2019. A number of changes have happened sense, or will happen soon. The IR compiler has stabilized, KSP support should be published for multiple platforms, and the Kotlin Native memory model rewrite is already in preview, and will likely be deployed in production next year. Library developers will need to understand these changes, but from a bigger picture perspective, these changes will allow for some missing libraries to be built, and pave the way for significantly broader adoption of KMP in the near future.

In this talk we'll cover:

  • basic API design
  • expect/actual vs interfaces
  • considerations around publishing
  • platforms to support (KMM or more)
  • memory model considerations
  • HMPP
  • compiler plugins and KSP
  • library ideas

The Kotlin/Swift boundary
3:40–4:20 PM • Russell Wolf

Kotlin/Native can compile to Objective-C-compatible bytecode, but that doesn’t mean it looks natural to native iOS developers. While Kotlin and Swift are syntactically very similar, they solve certain problems in very different ways. For example, a Swift developer often uses a struct where a Kotlin developer uses a data class. This means the default ways that things translate from Kotlin through Objective-C into Swift don’t always come out looking idiomatic

We’ll talk through some of these differences, and strategies for dealing with them. Kotlin, Objective-C, and Swift are three different languages, and so we shouldn’t expect to be able to translate between them perfectly. But with a bit of care at the interop layer, we can make things a lot smoother in the iOS code.

The right way to modularize your Flutter app
5:20–6:00 PM • Sam Ramezanli

One of the core system design principles for making any scalable application, is to know how to and what to modularize in your application.

In my personal experience, I've never worked for a company or on an app which will not need a major refactor at some point. Creating a modularized application will make this process much smoother and also brings tons of additional benefits which we will discuss in this talk.

In this talk we will start by discussing what modularization is and why we should care about it.

We will then learn about how modularization is possible in a Flutter projects, what are the differences between plugins and a packages, and will provide several code examples on how to test and run your modules in isolation.
