Trash Talk

Chet Haase, Romain Guy

With improvements in the ART runtime, developers should feel better about favoring good development patterns over memory-optimized-but-ugly-and-fragile techniques. But all of this is based on assumptions about the improvements of ART over Dalvik — what are the details?

This talk will examine some of the specific improvements that ART has made — over Dalvik and over time — and will demonstrate what these improvements mean for raw performance of garbage allocation and collection work.

Re-stitching Plaid with Kotlin

Florina Muntenescu

Many apps began adopting Kotlin and Android Architecture Components at the same time. While ostensibly quite different, the interplay of these two changes ends up heavily influencing each other.
Plaid is an open source example of material design concepts. It has a complex functionality but had a large amount of technical debt. We took the challenge of refactoring the app, following the Android Guide to App Architecture, while simultaneously converting the app to Kotlin—while keeping the existing functionality, fixing broken API integrations and adding new ones.
This talk covers the lessons learned while converting Plaid to Kotlin and integrating Architecture Components.

The Components of Material Design

Cameron Ketcham, Gautham Sajith

Material Theming launched this year at Google I/O, enabling you to systematically customize Material Design to better reflect your product’s brand. But how do you implement these customizations in your apps? What components and patterns are available? How do you extend them?
The Material Design Components library from Google offers a range of ready-to-use components which understand the Material Theming parameters. Come learn about the material theme attributes, the range of components available, and how they were built from the team that built them. We’ll also showcase some advanced usage such as shape transformation, how to deeply customize material components, and how to implement your own custom views which understand material theming.

Single Activity: Why, When, and How

Ian Lake

With the Navigation Architecture Component, developers have the tools to move towards a single activity structure for their app, but they don't know:

  • why they should move to that model
  • when it is appropriate
  • how exactly to take advantage of that structure and migrate to it

Get Animated

Doris Liu, Nick Butcher, John Hoford, Nicolas Roard

Android offers a range of animation systems—from ObjectAnimator, to window animations, transitions, physics based animations and now MotionLayout, which is a new class available in the ConstraintLayout 2.0 library that can manage motion and widget animation in applications.
This talk provides an exhaustive overview of the various systems, showing how and when to use each one, and how to make them play together nicely. Knowing the difference between the systems will help you to quickly and confidently use the right system to achieve any animation in your app.

Testing Android Apps at Scale with Nitrogen

Stephan Linzner, Vishal Sethia

Writing tests is a fundamental part of developing Android applications. Recent improvements to Androids testing APIs make it straightforward to write tests, yet it is incredibly hard to run tests at scale. In this session we give an overview of project Nitrogen, the new Android test harness, which helps developers to scale their testing with support for test setup, execution, device management and reporting.
