Talk: How to cook a well-done MVI for Android

Reactive programming has firmly become one of the modern Android developer’s tools. But most developers only use it in specific application parts concerning background operations. But what if we build an application solely on reactive patterns, what if we model our app as a single data stream? You’ve probably heard of Redux from the web world. It seems that per se this approach doesn’t fit Android, however, we can still borrow something useful from it.

In this talk, we’ll discuss how we can adapt Unidirectional Data Flow to a modern Android development and how Kotlin and its key features can help us in that. We’ll also take a look at examples of typical use cases implementation for this approach.

Speaker: Sergey Ryabov

Sergey is an Android Engineer in London, where he relocated recently after putting on hold his digital nomadic lifestyle. He is a co-organiser of the first Kotlin User Group in Russia and Android Academy in SPb and Moscow, usually speaks about Kotlin & Android. Rx addict, Kotlin early adopter.


Talk: Move over certificate pinning. Certificate Transparency is here!

Failing to protect your user’s data can not only result in fines but of course loss of your user’s trust

We can protect our apps against man-in-the-middle attacks using techniques such as certificate pinning. However, as we will see, implementing certificate pinning requires us to answer questions such as which certificate to pin against that doesn’t have a straight forward answer.

We will introduce certificate transparency which has already replaced certificate pinning in Google Chrome and show how to use it on Android with a new open source certificate transparency library from Babylon Health.

Speaker: Matthew Dolan

Matt Dolan has been eating doughnuts and developing with Android since the dark days of v1.6.
