About the speaker...
Arnaud GiulianiFor a while now, he has mainly worked as a Senior Android developer and keeps his hands in backend stuff. He has been a speaker since 2016 and mostly talks about Kotlin, Android & Koin. In 2017, Arnaud created Koin, a lightweight dependency injection framework for Kotlin. |
In this session, you will discover how you can adapt Unidirectional Data Flow for a Kotlin multiplatform project. You will explore mutliplatform alternatives to RxJava, such as Flow from Kotlin team and Reaktive from Badoo, and speak about refactoring a MVI project to untie it from JVM and make it reusable on different platforms. |
Day 1, 24 Oct starts 10:45 (Room 3 / Workshops)
Workshop: Unit Test Your Views - Part 1
|
You can benefit from this talk no matter what’s your level of expertise. As a junior, you will learn that you are not alone, that you can stop the impostors syndrome, and to be a better apprentice. As a senior, you will learn the benefits of being a good mentor, and how to become one. Lara will share her experience as a developer who is working on growing up in the career ladder. |
The measurements help you monitor if your app performance is slowing down. Because of this, you can integrate it to your CI. In this session, JB will share with you a real life scenario of benchmarks on the OLX app and show you how you can integrate it in your CI tool. |

In this session, you will discover the infrastructure around Google Play Billing Library and its usage. You will briefly explore the setup and basic implementation patterns inside of your app and then look behind the scenes and into the internals and implementation of the library itself. This approach will help significantly in gaining a better understanding of the library developer's intent. A part of the session will be a close look into and a discussion of the provided samples and the issues they pose. Looking at them with a critical eye it'll be possible to understand what the good and what the bad parts of GPBL are and how to structure your implementation the best way.

The talk will explore what these actions are, how to find them and examples on how to incorporate them into your daily use. In this talk you will not be relying on keyboard shortcuts since not all attendees might be using the same operating system with the same keyboard combinations and shortcuts. |
In this session you will also learn about: - Design tokens, what they are needed for, how you implement them and how they help support design in respect of synchronisation - About Badoo's Remote Icons Pipeline, how they parse icons from the sketch file in a synchronised manner on all platforms - How tokens and the Remove Icons Pipeline have assisted them all-round as they have made a global a/b test for redesign - How they reuse and customize their UI components between all their applications - And how this is scaled for all the company's applications (the development company grew twofold practically in two months), in order to scale development speed. They have a single MVIcore architecture, and this seamlessly leads to the emergence of a single approach to UI development. Artem will share with you the architecture of UI modules and how they allow you to have one layout for features shared by applications, so that these applications may be reused by applications among themselves. - And, of course, he will tell you about the problems they encountered at each stage

About the speaker...
Al SuttonAl has been contributing to the Skills Matter community for many years, in many different ways. He regularly speaks at Skills Matter events and conferences, including at Droidcon, at Londroid meet ups and Ouya meet ups and at Skills Matter's In-the-brain series. In addition to his support as a speaker, he has contributed lots of other great stuff, incredibly valuable to our community, his fabulous Droidcon app being a good example. In the late 90s’ Al started working in London for Chase Manhattan bank, initially looking after their developement infrastructure in London, and then moving on to looking after their DR facilities for Europe and become part of a global security architecture group. During this time Al didn’t leave his development roots behind, becoming involved in a number of projects including an attempt to port the Mozilla/Netscape browser to Java After the turn of the century Al spent a few years working for start-ups doing a range of design, development, and management jobs working on high volume, high availability systems involved in the telecoms and financial sectors. In 2005, he ended up working for Reuters after they took over a company he had been working for. At the end of 2005 Al left the land of employed work and started working for himself. At the end of 2006, he co-founded Enterprise Data Safe Limited based around a corporate password safe solution he had developed. Since then he's been responsible for all sales, development, and support activities within the company, growing sales and profits without the need for VC or bank funding. In late 2008 he founded Funky Android Ltd. which focuses on developing sites and software for the Google Android operating system. |

Zsolt and his Team now have over half a billion users across a growing portfolio of apps, including Badoo, Bumble, Chappy and Lumen. A year ago they set out on a journey to unify and scale up their approaches to reduce component reuse and maintenance times by an order of magnitude. They reached for maximal reusability and minimal coupling between individual components. Many of the lessons they learned in the process have immense practical benefits for projects of all sizes. |

In this session, you will discover the core principles or Jetpack Compose, what features it offers and why Kotlin is the language of choice. You will also explore how you can integrate Compose with existing UI frameworks and what you can expect in the future. |
Rendering UI takes a significant amount of CPU time, therefore it's important to keep this part of the computation as lean as possible. Whenever UI rendering regresses key metrics such as app startup, time-to-interaction, scroll performance are all affected which eventually affects product engagement. In this talk, you will discover how Facebook uses benchmarks to make sure that regressions on UI rendering do not slip through to production. Also you will explore ways of iterating on UI rendering code to proactively improve UI performance. |
Day 2, 25 Oct starts 10:45 (Room 3 / Workshops)
Workshop: Understanding Kotlin Coroutines
|
Today, with “serverless” backends becoming popular, server management and scaling is being fully automated, and you can use many of the same tools and languages you use for Android development. Do you want to write Kotlin everywhere? There’s a solution for you! Join this talk to explore some serverless options provided by Google, see some demos, and discover which options are right for you. |

The software you create is the expression of our knowledge, of what you’ve learned, and your own experiences. The path of becoming a senior Android developer can be very similar to the one cooks take to become chefs. Anastasia wants to learn from chefs and their journeys and apply it to your own craftsmanship. During her talk you will learn what path you can expect in your career, what skills will be needed in each step, what it takes to become a good Android developer, what it means to be senior developer, and finally how to lead a team successfully. |

Some of these bring users a lot of value, reducing friction to use a service or improving the user’s overall experience. But quite a few design patterns actually interfere with the user’s objectives. What should you take care of when building voice interactions into an app? Would any app benefit added voice commands, or does it only bring value to some use-cases? From interaction design to the dreaded issue of knowing when to stop speaking, you’ll learn what separates a great voice-enabled app from a not-so-great one. You will take away some lessons the current ecosystem can teach us to build better interfaces... and it might put a smile on your faces along the way! |
