Talks:
Break your app before someone else does

You can never really know just how secure your Android app is until you've done your best trying to break it.

In a world where building apps is similar to playing with Legos, the sturdiness and stability of our creations is mostly tested by others. Unfortunately, this places our users at risk of exposing their data into potentially harmful hands.

Let's dive together and explore a series of practical, hands-on examples on how to explore an Android app, dismantle it and alter it in a way it wasn't intended to be.

Behind the corner - hidden beasts of mobile apps security

Stories about micro creatures, hidden in the ocean of code, that have a huge impact on mobile apps' security. Especially on user's data and communication.

Beyond-the-basics dive into public and not so public security cases in the mobile apps world. Focusing on details, and sometimes doing really deep dives, the lectures aim at answering the questions of what was the real source of these vulnerabilities.

The goal is to inspire people to improve security analysis both at development and testing level. Providing efficient guidance using real, modern tools and based on memorable examples that stick.

The lecture does not focus on one operating system, making the lessons learned abstract but having practical, take-home solutions.

Building Microfeatures

Part of the success of most mobile apps these days is having the ability to iterate and deliver features fast. This becomes a challenge when the project and the team grows, and dependencies and friction between teams become more apparent.

In this talk I’ll introduce the concept of Microfeatures architecture for mobile apps. I’ll go through the core ideas behind it, show practical examples, and explain how development workflow has improved at SoundCloud since we started applying these principles.

Talks:
Building UI Consistent Android Apps
Consistency is probably one of the best known design principles. Consistent UIs are easy to use, easy to learn and frustration free. Nonetheless, they are also extremely easy to break! Just a few development iterations are enough to totally mess up your color palette or your icon sets.

Consistency gets even trickier if you have to ensure it across different Android apps. In such a scenario, defining style guides becomes crucial. Assets, icons, colors, metrics, and components should be easily accessible by developers/designers across your teams. Furthermore, you must ensure that every style guide change will not break your app.

Yelp ships its experience across Android, iOS and Web apps used by millions of users. In this talk, you will get an insight into the challenges we face on a daily basis ensuring our visual consistency, and the solutions we adopted.

Talks:
Reactive State Management with Model-View-Intent

Managing application state is not a simple topic especially on Android with a synchronous and asynchronous source of data, components having different lifecycles, back stack navigation and process death.

Model-View-Intent (MVI) is an architectural design pattern to separate the View from the Model. In this talk, we will discuss the idea behind MVI and how this pattern compares to other architectural patterns like Flux, Redux, Model-View-Presenter or Model-View-ViewModel. Furthermore, we will discuss what a Model actually is and how Model is related to State.

Once we have understood the role of Model and State we will focus on state management by building an unidirectional data flow.

Finally, we will connect the dots with RxJava to build apps with deterministic state management in a reactive way that makes maintaining and testing such apps easy.

Raymond Ho
Visual Lead at Zalando

Hi, I'm Ray and I work as a Product Design Lead at Zalando. After a product design degree, a couple of internships, and a foray into graphic design, I decided to start from scratch in a brave new world known as Web design.

This experience opened my eyes to usability and accessibility, and how that fitted in with the ‘traditional’ facets of design that include artistry and subjectivity. Since then, I’ve been mindful of continuing to engage in opportunities that merged these interests.

How to become a better (Android) developer

There are many ways every developer can get better. We can gain more knowledge, we can share it effectively with the others, we can take some actions in order to become more productive or to step out of our comfort zone.

In my talk I will go through every of these (and some more) giving references to the resources (books, sites, presentations, tools, plugins etc) I find helpful in getting better. Core part of my presentation can be applied to any software developer regardless of the technology, but the references will be mainly Java, Kotlin and Android specific.

So you have an application. Great! You dedicated lots of time and energy to work on it. You put together many lines of code. But who cares?

Making the app is not enough those days. With so many apps and new coming in each day it is not an easy thing to make users download your app. If there is a problem, there is a solution. It's ASO - App Store Optimization.

Let's see why and how it can help you to get downloads, means users, means money.

Talks:
Test Driven Swift To The Max - with or without the tests!

TDD has not been as central to iOS (and Mac) ecosystems as in some others. I'll argue that, not only is it an important and valuable tool to have in your toolkit, but Swift brings some things to the table to turbocharge it even more - so don't miss out!

I'll deconstruct TDD and rebuild it in the context of Swift - and the tools around Swift - so we can see how we can stream-line the process of writing and working with tests - and even question whether you even need the tests at all to do TDD! It's going to be fun.

The art of developing more in less time - how to not get caught by long build times?

While developing an iOS application at some point you may notice, that it does not go as smooth as it used to.

At the beginning everything was much smaller, it was easier to reason about, it did not take that long to build and it was much faster to switch between application and test targets.

The question is - can anything be done about it?Can we still develop continuously growing applications and do not fell the overwhelmed by them? The answer is - "yes we can”.

Let’s dive deeper into how we can make it happen by isolating and modularising components in our code. If we do it well, then we will always feel as we work on something small.

Don't mock networking, go end-to-end!

Maintaining a set of JSON files in your test bundle can be a tedious task. Hitting backend directly is a solution, but running your test suite can take forever.

Things get even more complicated when you want to have UI tests and check whole functionalities instead of single request-response dance. How about we hit a backend directly, but this backed is actually a fake one running on your iOS device?
