State Management of apps is getting more and more important in the world of JS Frameworks for web and mobile development. We all strive for interactive UI and less efforts to support stable UI updates and some data has been changed. But even more important is that the core of app, why the app was created, - its data and how we work with it.

In this talk, we will take a look at state management from data flow and architecture perspective, will touch basis of MobX and review the real-life experience of MobX integration into React Native mobile app, including difference of its usage for different platforms.
In Aleksander's presentation you will look under the hood of LiveData and coroutines to see how they are implemented and how it's even possible that LiveData can survive configuration changes!
The workshop is about specifications, how to check your components with keyboard and screen reader, and also touch on tools for testing and automation.

You'll walk through the best practices, common mistakes and study the ways of fixing them.

As a result, you'll get a solid foundation in the accessibility topic, which will facilitate further independent diving. You will understand:
• what things you should pay attention to;

In order to make your mobile app successful in the current world, it's better to develop it for 2 platforms: Android and iOS. But very often it is expensive and apps can have different functionality. The wayout could be to turn to crossplatform development: Cordova, Xamarin, React Native, Flutter as well as Progressive Web Apps.

During the round table discussion we are going to answer the following questions: what stage the crossplatform development is now; how effective it is and whether crossplatform apps can be as fast as native ones.

"Android O - Saving Our Galaxy 1% at a Time" by Yonatan Levin (KolGene, Israel)
Imagine Luke Skywalker flying to save the galaxy when he realizes his ComLink is running out of battery because of all the SnapChats C3-PO sent him of his homemade Oreos. With 1% battery remaining he tries to text Big Poppa Darth V. that he is alright and not to worry - when the communicator dies. These are serious, real-life problems we must remedy, people.

Thankfully, the new Android release is coming and with it new restrictions on background service to save user's' phone battery. The new restrictions require adapting architecture for your app. At this talk, we will delve into the various architecture and how they can be improved with the new changes.
