Vector Drawables were introduced with the Android L Developer preview and with the release of the VectorDrawableCompat support library there is no excuse for not making use of this extremely useful addition to the Drawables toolkit.
Mark Allison, author of https://blog.stylingandroid.com, will offer an overview of how Vector Drawables work and then share with you some examples of how to achieve some really cool animated icons using AnimatedVectorDrawable.
Jorge Barroso is the co-founder and Android developer of Karumi. Karumi is an intentionally small software development studio headquartered in Madrid and specialized in developing lean and stable native applications and working with teams for improve their skills.
Before Karumi, he worked 5 years as a Senior Tech Lead at Tuenti, the leading Spanish social network, and MVNO, part of the Telefonica Group. At Tuenti, Jorge developed a wide variety of strategic products covering J2ME, Blackberry and especially Android.
During the past years we have been discussing and iterating over our mobile application architecture at Karumi, and the result of all that work is called Rosie.
Rosie is a framework that helps application development by focusing on three pillars that we consider very important: testability, code scalability and code readability.
This talk is not about promoting Rosie but rather the creation process of this framework, the needs that we needed to cover and how we materialized all the literature present in tons of books and internet articles. This is about problems and solutions.
After more than 5 years working on Android, I have found a set of common problems that Android teams run into. In this talk we will go through a list of tips & tricks that can help these teams to improve their code and raise the quality bar.
The best practices do not exist, but the good ones do, and you will go home knowing a ton of them.

Asynchronous programming is bread-and-butter for the mobile developer. Virtually no native app works without remote API calls, and ways to achieve asynchronicity are many. Let's travel through this fascinating world of callbacks, futures and more.
While the author is an iOS developer, the topic is platform agnostic, and everyone is welcome.
Alexey Demedetskiy - an iOS engineer from Ukraine. He spent more than 5 years mastering software development skills in the area of enterprise and B2B applications.
He is focused on building simple and predictable architectures. His main values in software are short feedback loop and lowest possible cost of changes.
Did you ever try to test a single screen of your app? Or you constantly suffer trying to cover UIViewController with tests? You want to keep your architecture clear, but VIPER is too heavy to use? You want reactiveness, but don't want to use huge frameworks?
Trying to answer this questions I have come to simple and beautiful approach to structuring iOS apps. A simple way to abstract your view controllers as a set of presenters. Each presenter is able to present one thing at a time. Several presenters can be built into components, which can be joined in more complex components.
I will describe main advantages of this approach, illustrate it with an example project and compare with modern iOS architectures: VIPER, MVVM, MVC.

Somewhere in the heart of a development process, essential to the very being of a product's existence, are the people who write, consider and wrestle with code. What motivates and demotivates them? What are the intellectual challenges and rewards? What are the skills they have and need and cognitive biases and environment they work with and against?
This talk considers the act of programming and those who do it and want to get better at it, from the perspective of development process to craft, from architecture to code.

The power of sketching lies in using sketching to ideate, iterate, and communicate our ideas. It is time to gain the confidence you need to sketch in person or in front of a group. By harnessing the power of sketching we all can become sketching machines.
Sketching is a crucial skill that spans all job titles. It helps with brainstorming ideas, iterating through concepts, and communicating our ideas to others. Whether working individually or in a group, our ability to sketch helps take the abstract ideas out of heads and into the real world. If you’re not comfortable sketching then there is little chance that your ideas will stick with you, your team members, and even your clients.
Don’t worry—the confidence you need to put your pen to paper and start to sketch is close at hand! With the addition of a few simple approaches to your daily routine, you too can harness the power of sketching and become a sketching machine. Come prepared to do fun sketching activities so you can experience the power of sketching firsthand.

Performant applications are one of the key drivers of success in the mobile world. Users may abandon an app if it runs slowly. Learning how to build applications that balance speed and performance with functionality and UX can be a challenge; however, it's now more important than ever to get that balance right.
This session will show you how to wring the most from any hardware your app is installed on, so you can increase your reach and engagement. An introduction to state–of-the-art Android techniques and the importance of performance in an Android application will be introduced, and later we will slowly walk through the Android SDK tools regularly used to debug and profile Android applications, learn about some advanced topics such as building layouts, multithreading, networking, security and battery life (one of the biggest bottleneck in applications).

Each app has his own story - from proof of concept or idea, going through very first MVP versions developed by one coder, ending with full valuable platform maintained by bigger teams.
Building successful product means that we constantly need to react on changes and new requirements. Develop new features, maintain and fix current codebase. Adjust code architecture to bigger team and being still understandable for newcomers.
And this is our story - about looking for balance between fast and reliable, transforming house of cards into castle. About solving the real issues with abstract patterns, architectures and tools. About practical profits from Dagger 2, MVP (and other code architectures), different ways of testing and automations.

Mobile's role is both very dangerous and very important in system security. We will talk about how mobiles change traditional security layouts and dictate client-server relationships. How to protect the most precious and sacred thing - the user's data.
We will see how to build security system, that does not fail when application keys are exposed; when servers are hacked; security that lasts as long as unique user's crypto keys (or passwords) are safe. We will learn about thin transparent security layers system and its applicability in client-server systems. Putting secrets known by the user to be a source of trust is the ultimate way for the app to become "thin" in relation to the security model, thus lowering the risks and developer pain.
