Jetpacks For You And I

Marcos Placona, Developer Evangelist

Twilio

 

Lifecycles, navigation, camera, database access… To name a few of the most complex APIs to work with Android.

In 2017 Google introduced Jetpack, a collection of Android components that make it easier for you to develop great apps, follow best practices and avoid performing complex tasks or writing boilerplate code. It's also HUGE and with over 30 different components in the collection, getting started can be daunting if you don't know what is what.

In this talk, we will look at what you need to get started with some of the hottest Jetpack components that offer backwards compatibility and are updated more frequently than the Android platform.

CameraX - The New Powerful Jetpack Library

Divya Jain, Mobile Developer

Gametime

Camera development has been quite a painful task. But now comes the new Jetpack library : CameraX. With a use case based lifecycle aware approach, it provides a consistent & easy to use API. In the talk, I will talk about:

  • Overview & architecture

  • Library structure with 3 main abstracted handles

  • Binding the use cases to the Lifecycle

  • Primary benefits

  • Sample app code to demonstrate how to get started

 

The goal is to help everyone understand how this library aims to strike a balance between abstracting away the difficult bits of managing the camera while allowing flexibility and customization. The “Click of a camera” has just become easier!

Become A Composer

Brian Gardner, Developer & Instructor

Big Nerd Ranch

Jetpack Compose is a new toolkit that radically changes the way views are created on Android. It provides a fluent API to declare view components and combine them into a screen.

This session shows off how to create a screen from a popular Android app using Compose. I will start by creating the low-level, individual view components, then combine them in higher-level components that represent larger parts of the screen. Once the screen starts to take shape I will add state into the mix and demonstrate how to display the state and update it as well.

 

By the end of the session, viewers will have confidence in their ability to use Compose to quickly create a user interface for their apps.
