SPEAKER 2: First, we'll start with distribution. you.

You saw in the keynote, we introduced the dynamic app

Towards the end, it was pretty clear it's pretty easy for you.

All you have to do is click a different menu

It's going to be faster and easier for your users

SPEAKER 1: Let's talk about Android Jetpack.

guidance on how to build better Android applications.

All of you are familiar with most of what

What we're doing is adding to it over time

with stuff that's going to make it even better.

is what I like to think of as a refactor, because it's

And we're doing a whole lot of tedious renaming.

And we're also providing tools to make it easier

for you to do the similar refactoring that you're

Everything is being renamed to something more appropriate

Jetpack architecture is about architecture components

and then iterated with feedback from the community,

Also navigation-- it turns out that up versus

back is a hard problem for applications to solve.

We are making that much easier, and we're

integrating with the tool to make it even easier yet.

We want to make it better for all the Kotlin developers

I'm sure there's a lot of you here today.

The ART team has been really busy with D8, R8, and ART

They've been looking at the bytecode generated

They've analyzed some of the bytecode patterns that

were different from the ones generated by the Java

And they've been optimizing for those patterns.

We've also been adding a lot of nullability annotations

to our Java APIs, both in the core libraries--

to make it easier for you to use the platform

It's a set of Kotlin extensions for existing platform APIs.

And the goal here is to try to take advantage

They're already easier to use just by using Kotlin,

but with the extension, they get even better.

SPEAKER 3: So Slices is our new approach to remote content

that you can actually use to project UI into your own app

This is not sort of here's a canvas or an absolute layout.

We give you a structure to fill out and a whole bunch of very

flexible templates in which to populate that data with some

display hints, so that the receiving end of the Slice--

This is meant to be something that holds rich UI-- sliders,

controls, live information, possibly videos--

things that actually feel like real UI as opposed

to a snapshot of something happening in a distant process

and this is how they're passed around the system

and how they're passed along to app indexing

It's entirely in Jetpack, so it's backwards-compatible.

You can use Slices all the way back to API 19.

You can think of these as shortcuts with parameters.

[INAUDIBLE] likes to think of them as visible intents.

This is essentially a deep link into your app
