MCE is the conference created by developers and designers. Getting bigger every year it touches the aspects of all elements of mobile creation - development, design, UX, and technology. Our goal is to get a holistic picture of mobile devices of all kinds and take a next step in their development, getting to give users the “WOW” impression. 

Do we have your attention already?


We invite you to take part in the workshop event at MCE - JITTER. With the option to choose from several different topics, each attendee will have an opportunity to participate in workshops related to technology, product and design of mobile applications. On top of that you can choose to roam freely around the venue where it’s going to be held, allowing you to pick up and try out new, exciting tech products. Stay tuned - we’ll be announcing more about it.

Android App Architecture for the Everyday Developer

MVC, MVP, MVVM, Clean and more keywords might sound familiar to you, these describes patterns that helps developers building high quality software by organizing things up. But why bother? why not stick to the classic 'don't fix what ain't broken'? A well planified architected app can speed up the development process and simplify the long term maintainability. It's not enough to keep functions smalls and not building a god-Activity, we need to level-up and design towards clean architecture. This talk will review and discuss MVP and Clean approaches, how to start, and tips on architecting our apps in a compelling way.

Life Without Fragments

What is wrong with Fragments as they are implemented right now? You hear a lot of rage around bugs, issues, and plain bad/obscure APIs. But what alternatives are out there?
Most of the time, Fragments are used as custom Views. But that’s overkill for Fragments, and it’s not what they’re meant for, either: they can do way more than that (and probably shouldn’t). The talk will run through the architectural choices that we found out helped us create great apps without getting lost in Fragment hell. Because #fragmentsmatter, but not more than… [dramatic music mounts to climax, screen fades to black. ""TO BE CONTINUED"" appears on screen]

Building Swift Libraries for iOS

I'll look into the internals of a Swift library developed for iOS that heavily uses UIKit and the ObjectiveC runtime. Since those are two dependencies you can't get rid off why not make the best out of them? I'm going to look into how I could stand of the shoulders of giants to deliver a slim but flexible Swift lib with the ObjectiveC runtime blessing.

Design Challenges - how to analyse information, how to form insights, how to divide them into categories to form design challenges. [brains on]

The design process should have a structure to be efficient and enable managing change. Creating a design challenge is a cruicial part of developing any project - after studies and research, after gathering insights comes the time to synthesize all the information and look for new ways to answer peoples' needs. A well defined challenge should be an effect of thorough work and not just intuition or pre-concieved ideas about solutions. It should describe the people involved and the final state we want to reach. If the challenge is defined correctly, it opens up new pathways to create new products - even those that are not so apparent at the first glance.

Francisco Franco

Francisco Franco is an Android developer with six years of experience building applications and custom kernels for Nexus devices, focusing on improving battery life and improving feature extensibility on the platform.

Francisco has built several apps and services, the most popular being FKUpdater which serves as an interface for managing his custom kernels and offers an easy way for users to stay up to date. Francisco also built Focus, an innovative photo/video gallery replacement that showcases material design at its best. He also has experience with startups in Silicon Valley, contributing to the project that began what is now known as Android Auto.

He spends his free time finding new challenges to tackle, the latest being an exploration into mutative design with Liam Spradlin.


The Living Interface: Mutative Design

Mutative design is a theoretical design methodology that would allow interfaces and experiences to be born, live, and evolve according to a user’s realities.

With mutative design, things like physical ability, lighting, and vision are accounted for automatically, allowing interfaces to be engaging and accessible to every user, without compromise.

In this session we’ll give a brief overview of the rationale and process behind mutative design and take a look at the first mutative sample app - Selene. We’ll walk through Selene’s first mutations from design and development perspectives, and explore what’s next for mutative design.

Android App Security on a Budget

Even with all the time & budget in the world you can't make a completely bulletproof app, so how do you stand a chance with a real world app? Real world apps have limited budget, are short on time and the task priorities are often decided by the security oblivious client/project managers. 

So what can we developers do to increase our app’s security and help protect our professional reputation? Where should we focus our app security effort? Isn’t security really difficult? and what gives us the biggest bang for our buck? 

We will answer these questions and show that improving your security need not be technically challenging or time consuming. Also I’ll illustrate that it doesn’t necessarily need buy-in from stakeholders. We’ll be using commercially viable open source libraries to level up your app’s network verification, tamper protection, device integrity checks and more! while keeping in mind a shoestring budget!

Many of the presented security protection techniques can be applied to iOS apps too, however the focus and examples will be Android.

ReactiveCocoa Reloaded

ReactiveCocoa is the first and most commonly used implementation of the reactive paradigms in Cocoa, with a lot of bindings to UIKit/AppKit frameworks to help connecting reactive signals to UI elements. I was lucky to work on a huge Objective-C codebase with heavy use of ReactiveCocoa prepared to be released for millions of users, so I have some pros and cons in my pocket even for that scale. I'd like to discuss the state of ReactiveCocoa in 2016, to help people to understand their possibilities especially if they are in the phase of moving to Swift. I'd like to share the main differences of the new ReactiveCocoa Swift API with code snippets. What are the conceptual changes, in comparison to the v2 Objective-C API. Some examples of other libs, like RxSwift and what are the main differences in usage.
