Orhan Obut
Android Google Developer Expert (GDE).
Android Developer at Blacklane.

Life of APK

Android application development seems to have only a few steps: Write code, assemble it and deliver.

But how does your code actually work during the assemble? What transformations it gets and delivers to the end user? What happens to your resources, source files? How does the compiler work for android? Why do you need to sign your application and what happens after the user launches your application? And many other questions.

In this talk, I'll try to explain all steps behind the android development from writing code to launching the application. I will try to reveal all those magics behind the assemble process.

John Sundell
Lead iOS developer at Spotify.

Taking Objective-C to the next level

We're all really excited about Swift these days, and even though most people agree that Swift is the future of iOS development - most of us still have a lot of Objective-C code that we have to keep working with. Instead of being frustrated with Objective-C, or do something radical and rewrite your whole app in Swift - there are a ton of modern concepts and design patterns that can easily be implemented in Objective-C, as well as in Swift.

During this talk, John will show some examples on how Spotify keeps moving its Objective-C codebase forward, and how you easily can improve the quality, testability and predicability of your Objective-C code. There will be live coding!

Critique of “library” approach in developing for Android

Recently there is an explosion of interest to the development of Android applications using the external SDKs and frameworks. First of all, this is due to the energetic activity of such companies as Square and Facebook.

And while we generally have no questions concerning the libraries that perform purely utilitarian functions and help without writing any extra code, the excessive use of libraries and frameworks that impose their rules of the game on top of the native one often leads to negative results.

The aim of the report is to review the negative aspects of the use of such libraries as EventBus, RxJava, Mortar etc. compared to the development using native tools Android Framework, and explain to the audience the idea that any library, framework or SDK is primarily a tool, the efficiency of which depends on the understanding how it works in the context of a specific task.

Windows 10 – one application for all platforms

After the release of the latest operating system from Microsoft, developers get a great opportunity to write single code, develop single view and get a single application that runs on all Windows 10 devices. Just imagine - you do not need to worry about various API on different platforms, different design guidelines. But how could you use this opportunity for the 100%? How could you create a high-quality mobile app that works everywhere, using all existed possibilities?

In this talk, I will tell you how to create a high-quality application for Windows 10, what problems you may encounter and how to solve them and the new procedure of compiling .Net Native.

Anton Minashkin
Android developer at GlobalLogic.

Data transfering: faster, stronger, better and not harder

Almost all mobile apps should communicate with server or even with each other, some of them should store something and definitely all of them should work as fast as they can. One of the bottlenecks in performance of these apps is operations with data. Actually almost all apps are all about the data, they send it, store it, process it, receive it and somehow show it to the user. So to make your app really fast you definitely need to find a way how to make data processing really fast.

So let’s discus what tools do we have right now for this, how and when should we use it and how this will make your users happier.

About speaker

Android developer, Team lead, currently works at Global Logic. Have experience in both server and mobile side development. All my free time I spend on the endless search of silver bullets, perfect architectures and holy wars.

Serhiy Poplavskiy
Microsoft Ukraine.

Azure App Services for creating backend of the mobile applications. The example of the deployment of Parse Open Source on Azure.

Mobile telephones enter deeper into our lives from year to year. At the same time, not only do they in a private life, but also in working one. A mail, a calendar, a corporate messenger, an office suite and specific applications even now allow us to keep the business on the pulse and carry out the work, being far away from a computer. Being always online is a modern trend. Despite the fact that every year the mobile devices become more productive, we still cannot bring all the business logic on the client side. On the other hand, the mobile devices run on different platforms and the application support issue becomes particularly critical if different commands work over the same functionality for different types of devices.

The cloud helps us in addressing these issues. Bringing the business logic of applications to a centralized backend, we can achieve the ultimate efficiency of the application operation and facilitate support.

In this report, we will talk about the principles of building of the fault-tolerant and scalable server-based applications for mobile devices. We will have a look at the functionality of the Azure cloud services for the mobile application developers, as well as we will have a look at the process of the deployment of these solutions, as exemplified by the Parse platform, which recently became the Open Source.

About speaker

Serhiy Poplavskiy is Microsoft Ukraine representative responsible for technical support of software developers on Microsoft Azure platform and Developer Tools in Ukraine. During his tenure, he delivered more than 40 deep technical training on these topics, was part of development team in several projects based on Microsoft Azure platform and have deep practical experience in implementation and deployment solutions based on this platform. Serhiy has many years .Net programming experience using Visual Studio, implemented several own applications for Windows Phone, Windows and Azure platforms.

Alexander Zimin

Zeyad Salloum
iOS Developer at Zalando SE

The Flexible Layout Kit (how we got rid of web views)

Content is King! At Zalando, our content is changing every day. fashion trends come and go and new items enter our warehouses every day. Discounts happen over night and every so often we want to present a new feature on a landing page. On websites these changes can be pushed to the public within seconds. But with Native apps we have release cycles measured in weeks or at least days.

In this talk, I’ll cover how we tackled this problem at Zalando by creating a framework we call Flexible Layout Kit. Flexible Layout Kit is a layout engine that translates JSON content into native iOS interfaces. it’s made up of a collection of elements that can be contained inside each other to form amazing native UI.

About speaker
