Functional approach to Android architecture using Kotlin

By Jorge Castillo

Modern languages with functional colors are mainstream lately. Kotlin is arising as one of the most powerful ones, and developers around the world are using it for personal and professional projects. It's time for Android devs to look forward and benefit from this fact, and start designing more advanced architectures based on the features provided by the language. On this talk, I will showcase a Kotlin approach (plus a sample project) to learn how to move all our side effects in the edges of our system, and implement a functional oriented architecture for our Android apps based on purity. Testing will also take part on the talk. I will also showcase a functional programing lib we are working on in the spanish community, called kategory: https://github.com/kategory/kategory If you feel OOP is just not enough and want to make a huge step forward, come to this talk. You will not regret!

Android Architecture Components Considered Harmful

By Vasiliy Zukanov

Applications architecture is a broad and important topic in software development, which has been neglected by official guidelines for Android for a very long time. In spite of that, the interest in architecture among the members of Android community has been growing steadily over the years. Official guidelines and tools slowly caught up with the community interests, which culminated in a recent announcement of a set of libraries called Android Architecture Components by Google developers. While the motivation behind Android Architecture Components is clear, the relation between these libraries and application architecture is not so evident. Furthermore, the way these components address the issues that Android developers experienced over the years hides a new set of potential issues and gotchas under the hood. In this session we will attempt to understand what software architecture is and what it isn't, and discuss several potential pitfalls associated with Android Architecture Components.

Using Android Things to detect & exterminate Reptilians

By Gautier Mechling

Whether you believe it or not, the Reptilians are everywhere, and we have never been ready to face them so far. We WERE NOT ready... But this will finally change, now that Android Things has been released. Trust me, they didn't want to see that happen. Together, we will discover Android Things and see how we can create a moving machine capable of detecting Reptilians (with touch/skin temperature sensors, and machine learning), but also capable of exterminating them (btw, I would appreciate if the staff could lend me a flame-thrower, it would make a great demo). How? Using a Raspberry Pi, an Arduino, and discovering+using some specific Android Things APIs, such as gpio, pwm, i2c, spi, uart, allowing us to interact with physical components. Come see the power of Android Things.

Building CI pipeline based on TeamCity & Docker in Android Team

By Paweł Gajda

Nowadays, there are a lot of hosted CI solutions that offer quick integration with our repositories and need just few clicks to finish initial setup. Other services, coming with enhanced functionality, but requiring a server to maintain are often not given a try. First problems occur when we start coping with long compilation time and limited resources, especially during instrumented tests running on the Android Emulator. Here TeamCity comes with a rescue. With simplified setup (using Docker) and few tricks, reducing time for possible management, we do not need to hire a DevOps engineer.

Make your app instant

By Yuliya Kaleda

Instant Apps is a bridge between seamless web experience not requiring installation and truly native user experience with material design and navigation. It absorbs the benefits of both worlds. As Google's early access partner, Jet.com got access to Instant Apps API and tools in their early experimental stage. I was leading Instant Apps project for the last 8 months at Jet.com and would love to share the experience. Building Instant Apps required a lot of work on the architecture side, modularization and reducing the app size. In my talk I will touch the following points: - Instant Apps types - Architecture changes - Size and feature constraints - Pain points and lessons learned - Ways to slim down the app and bring it down to 4 MB - Benefits

DevOps in mobile?

By Tomasz Pająk

Developing an app being a consumer product means working under constant pressure to frequently release features that bring value to customers. Several-months-long development with no release to production happens very seldom in the aforementioned context. How to cope with a need for speed of releasing an app eg. once a week? If you look at what happens in a ‘backend world’, DevOps is the new hype giving a promise to deliver value in a stable way very often. However, DevOps is very often associated mistakenly only with Continuous Integration and Continuous Delivery. I will be talking about increasing overall flow of value to customers, shortening feedback loops from customers and building an organization which is optimized for speed and stability. Moreover, what practices considered with DevOps in a ‘backend world’ are valid in a 'mobile world'? On the other hand, what practices need to be re-thought taking into account the mobile context? I will not be able to answer all the questions as I don’t know all the answers. However, the answers I have are based on what Facebook, Netflix, Etsy and - where applicable - Seqr do, don’t do or were doing wrong. The goal of my talk is to help people to understand DevOps comprehensively and how it fits into mobile context. I will refer to certain technologies as examples but will not discuss them in detail.

Don’t fear SQL: A better way to store and handle data with SQLBrite && SQLDelight

By Leandro Favarin

For many people, SQL can be intimidating when writing mobile apps. To avoid its complexity, various libraries started to implement techniques such as Object-Relational Mapping. They ease basic operations on complex objects, but come with a set of downsides such as decreased performance and the learning curve of a new library. Square’s libraries SQLBrite and SQLDelight improve data manipulation by embracing all the powerful capabilities of SQLite while removing common frictions like runtime crashes, boilerplate code, and type-unsafe APIs. In this talk I’ll present the reactive mindset behind SQLBrite and the code-generation capabilities of SQLDelight. When combined, these two libraries will help you architect and code safer and faster with queries autocompletion, code reuse, and much more.
