  • [MUSIC PLAYING]

  • PATRICK BRADY: I'm Patrick Brady from the Android Auto team.

  • And I'm here with Lauren, Rasekh, and Dean

  • to give you an update on Android in cars.

  • We've got a lot to cover today and a lot of automotive puns.

  • So let's buckle up and get driving.

  • We're incredibly excited about the automotive space

  • right now because we see it going

  • through huge transformations, from

  • electrification to connectivity, sensors and input

  • devices, sharing and autonomy.

  • Cars are rapidly turning into full-blown computers on wheels,

  • with high-speed mobile connections, microphones,

  • cameras, and screens everywhere of all shapes and sizes.

  • It's a computing transformation unlike many we've seen before.

  • And it opens up new opportunities

  • for innovation and for developers.

  • Android Auto is an effort from Google and our partners

  • to bring these advances together and create

  • a safe and seamless connected experience for drivers

  • everywhere.

  • Of course, that's a lot easier said than done.

  • There are dozens of different car platforms

  • today, many different input types,

  • from touch screens to touch pads and rotary controllers,

  • many different screen shapes, and sizes, and resolutions.

  • Layer on top of that the myriad driver distraction

  • guidelines and regulations across the globe.

  • If every software developer had to deal

  • with this level of complexity, we

  • would never be able to realize the potential that automotive

  • holds.

  • Well, at Google, we believe that platforms

  • can reduce that complexity and allow developers to just focus

  • on innovation.

  • We saw that happen on the web and in mobile.

  • And we're working hard to do the same thing here,

  • making Android the platform for the car.

  • Today, you can see that vision at work in any Android

  • Auto-compatible car.

  • Drivers have access to their favorite apps

  • right from the car's display.

  • And developers build their app once for every car,

  • without having to worry about the make and model, the screen

  • size, the input type.

  • We started this journey back in 2014,

  • partnering with leading car brands

  • to bring Android Auto to their cars.

  • We've made a lot of progress since then,

  • and I'd like to give you just a quick update on how

  • things are going.

  • We continue to see incredible growth in compatible cars

  • and aftermarket systems, with over 500 models

  • available today from 50 different brands.

  • Since last I/O, we've seen first launches from Fiat,

  • Alfa Romeo, Tata Motors, and Smart; and 2018,

  • bringing exciting new launches from Jaguar, Land Rover, Mazda,

  • and many more.

  • Just last month, JVC and Kenwood launched the first head unit

  • supporting Android Auto wireless.

  • We're really excited about wireless,

  • and we look forward to more partner launches in the months

  • ahead.

  • With these great partnerships, we're well on our way to

  • making Android the platform, the developer platform,

  • for every new car shipped.

  • But what about the 1 billion cars on the road that

  • predated Android Auto?

  • What do we do for those cars?

  • Well, of course, we know not everyone

  • has a compatible vehicle.

  • So we made the Android Auto app available to all Android users

  • as a standalone experience.

  • And this opens up the platform and the ecosystem

  • to many millions of drivers, no matter what kind of car

  • they drive.

  • And as we've made Android Auto available to more cars and more

  • drivers, we're happy to say that the strong user

  • growth continues.

  • Here's where we were in I/O 2016,

  • I/O 2017, and today, at I/O 2018.

  • We've seen over 300% user growth in the last year alone.

  • In fact, as you can see on the chart,

  • our growth is accelerating as we make

  • Android Auto available to more cars and more drivers.

  • And that consistent platform and large install base

  • is a great opportunity for developers.

  • So we continue to see strong growth on that front, as well.

  • In the last year, with some popular apps

  • like Waze, Google Play Books, TextMe, Sirius XM, and Plex

  • launching Android Auto, Google Play

  • now has thousands of Android Auto apps available.

  • And that's a 200% growth from last year.

  • In January, we also launched the Google Assistant

  • in Android Auto, opening up a new way for drivers

  • to stay safely connected in the car and for developers

  • to build car-friendly experiences.

  • And the great thing is actions built for the Google Assistant

  • work across the Assistant services,

  • from smart speakers to TVs, wearables, and mobile.

  • We're excited about some of the early favorites in automotive,

  • such as Spot Hero, which helps you find and reserve

  • parking spots; busuu, bringing personalized language learning

  • right into your car; and CNBC, bringing you

  • the most up-to-date business news and market

  • insights on the go.

  • The Actions on Google ecosystem is exploding,

  • and we're super excited to see what you all build next.

  • But of course, that's just the beginning for Android in cars.

  • As cars advance, we have the opportunity

  • to create an even more seamless experience by building Android

  • right into the car itself.

  • And that's why we started an effort back in 2016

  • to build automotive support right into the platform.

  • The first demo of that work was right here at I/O in 2016

  • with this concept Maserati.

  • With a lot of help from the industry,

  • we're investing in building automotive features

  • into each Android release, making Android a turnkey

  • platform for infotainment, just as it's been

  • a turnkey solution for phones.

  • And the rest of the industry is taking notice.

  • Last year, two of the world's most innovative car makers,

  • Audi and Volvo, announced that Android will power

  • their future in-car experiences.

  • If you had a chance to see the in-car demos last year,

  • we think you'll understand our excitement for the future

  • and why we look forward to many more car makers

  • following in their tracks.

  • Earlier this week, Volvo and Google

  • announced a partnership to bring Google services

  • to the next-generation, Android-powered Volvo cars.

  • With the Google Assistant, Google Maps, and the Play Store

  • seamlessly integrated into the Sensus system,

  • were creating a new benchmark for the connected driving

  • experience and a great opportunity

  • for all of you, our developers.

  • And of course, this all works no matter what kind of phone

  • the driver has, or even if they leave their phone at home.

  • To get a preview of that experience today,

  • swing by the Android Auto Sandbox,

  • where you can see it live and in action in the next C40.

  • So we've made a lot of progress since Android Auto first

  • hit the road.

  • And we're well on our way to establishing Android

  • as the platform for automotive in old cars, new cars,

  • and the next generation of cars coming up the road ahead.

  • But of course, it's not enough to just make Android available

  • everywhere.

  • We're also working hard to make sure it's

  • the best possible experience for our users and our developers.

  • We've listened to them a lot over the last year,

  • talking with great developers, like Spotify and others,

  • to hear what they want to see from Android Auto next.

  • And today, I'd like to give you a sneak peek at some

  • of the exciting changes we're making

  • and what it means for the developer community.

  • So now, I'd like to invite up Lauren

  • to tell us where Android is going next.

  • [APPLAUSE]

  • LAUREN WUNDERLICH: Good morning, and hello, everyone.

  • My name is Lauren.

  • I'm going to be speaking about some of the new challenges

  • we are facing on the auto space and how we're adjusting them.

  • We've spoken before about why we building Android Auto.

  • And at the core of our experience

  • is our overarching commitment to bringing a safe and connected

  • experience to every vehicle.

  • This is particularly important, as the primary responsibility

  • of the driver is to drive.

  • Everything else we do is secondary.

  • To really highlight this, we showed a photo

  • of a driver playing Pokemon Go during one of our research

  • sessions.

  • Don't worry, everyone was safe.

  • We were parked.

  • But this extreme example showcases the struggle

  • we face while balancing the tension we

  • feel between balancing our digital and our physical lives.

  • By developing strategies to manage attention,

  • we can provide a safer in-car experience

  • to keep drivers connected.

  • And as you heard from Patrick, screens

  • are getting bigger, wider, taller, more shapes, and more

  • inputs, such as touchpad.

  • We are starting to think about how to evolve our UI to better

  • scale and adapt for the future.

  • The best part is, as developers, you

  • don't have to worry about these layout changes, display size

  • variants, or even supporting those input mechanisms,

  • because the Android Auto platform takes

  • on these challenges for you.

  • Furthermore, we're looking to see where

  • Android Auto is going next.

  • As part of our commitment to developing the best possible

  • in-vehicle experience, we are developing

  • a built-in experience that feels more at home in the cockpit.

  • So I'd like to introduce our new Google In-Car Concept.

  • From design's point of view, the goal of this concept

  • is to adopt Android Auto's design

  • to a vehicle-specific theme.

  • This includes additional ergonomic details

  • and nods to the vehicle's interior design.

  • We can leverage these vehicle concepts to prove out

  • new features and designs, working with our partners

  • to bring them to life.

  • And besides abstracting hardware complexity,

  • we're also thinking about how to enhance our core experiences

  • and introduce new ways to promote your content.

  • Today, we'll be highlighting some of the updates

  • to messaging and media experiences.

  • But be sure to stay tuned as we roll out

  • all of these updates this year.

  • For a live demo of these vehicles,

  • including a preview of this onscreen experience,

  • stop over to the Android Auto Sandbox.

  • As part of helping drivers stay connected,

  • with user interfaces that are safer and more predictable,

  • we have developed multiple ways for you

  • to integrate with Android Auto, depending

  • on the nature of your service.

  • For navigation apps, we work directly

  • with developers to ensure they follow our strict distraction

  • guidelines.

  • And you can also integrate with the Google Assistant,

  • which is voice-centric and ideal for in-car use.

  • Be sure to check out their sessions this year at I/O.

  • Messaging and media make up the largest number of apps.

  • And today, we'll be speaking about the updates we've made

  • to both of those experiences.

  • So let's dive in.

  • Beginning with messaging updates, communication apps,

  • like WhatsApp, Telegram, and Messages,

  • integrate with a messaging template

  • and are displayed via notifications.

  • Notifications require less effort

  • and are highly visible throughout the experience.

  • We've improved the notification layer this year,

  • including more and unified actions.

  • More and unified actions across the surfaces

  • help drivers react to incoming content

  • without ever leaving their current experience.

  • And group messaging, a feature developers and drivers

  • have been asking for--

  • now you can stay connected with multiple people

  • at the same time.

  • Media apps, like Spotify, Pandora, Pocket Casts,

  • and iHeartRadio, integrate with the media template.

  • The template is designed to remove

  • these complexities, such as input,

  • screen sizes, and orientations.

  • And they're also designed with the industry's best practices,

  • promoting predictability for drivers

  • across all of our systems, including

  • the phone screen, car display, and built-in experiences.

  • We are thrilled to showcase some of the biggest redesigns we've

  • made to the media experience since launching Android Auto.

  • By focusing on these three key areas--

  • media template-- we have personalized

  • a modern, content-forward experience

  • for all of our drivers.

  • New architecture, more flexible UI components, and new search

  • capabilities make up the majority of our updates.

  • So let's dive in--

  • new architecture.

  • Before, when drivers got going, they

  • would have to navigate to the media section, open the drawer,

  • and find that very special commute playlist.

  • Now, when a driver gets going, they no longer

  • have to seek out the content they wish to play,

  • but the content is brought forward in a very visual way.

  • We've re-architectured the media template in order

  • to pull the content out of the drawer.

  • Drivers can easily see content, saving additional taps,

  • and getting on the road just faster.

  • Our new foundation has created many more opportunities for you

  • to showcase content, for which we've

  • introduced more components to promote a new flexibility

  • and ability to express your content in a more familiar way

  • that is native to the app.

  • Now, you can create more customized layouts with list

  • views and subheadings, as well as

  • grid views with really large graphics, additional, richer

  • metadata hints, such as explicit content tags, downloaded tags,

  • and new and in progress tags.

  • With the added benefit of the template approach,

  • each of these new additions are available regardless of theme.

  • From the Android on the phone or on a screen up,

  • as well as customized by the OEM,

  • your branding and layouts will be respected.

  • See firsthand how we're doing that with the Google In-Car

  • Concept at the Android Sandbox.

  • Our last major update showcases a new search and pivot

  • functionality.

  • Search is still hands free.

  • And when a driver asks for a specific song or artist,

  • it just begins playing.

  • In addition to playing the best-matched song or artist

  • automatically, drivers can now pivot

  • into the app for app-provided content and related

  • suggestions.

  • With the new search functionality,

  • we've further optimized the search results

  • to include more digestible format.

  • Things like subheadings and subgroups

  • help drivers find the content they're

  • looking for even faster.

  • So that's what we've been working on

  • to enable a healthy in-car ecosystem.

  • I've showcased the new messaging updates and media updates

  • by focusing on the new structure, new components,

  • and more search capabilities.

  • So I'd like to turn it over to Rasekh

  • to teach you how to get started with these new updates.

  • Thanks.

  • [APPLAUSE]

  • RASEKH RIFAAT: Thanks, Lauren.

  • Hi, I'm Rasekh, and--

  • oh, there we go--

  • I'm here to talk to you about what developers

  • need to do to support our new messaging and media app

  • features.

  • Today, I'll go through some code examples that

  • will let messaging apps use support group notifications

  • and using MessagingStyle.

  • I'll also go over our media architecture

  • and show you how to provide those in-app search results

  • that Lauren just mentioned.

  • And then finally, I'll look at code changes

  • for media apps to enable our content browsing visuals.

  • Let's start with an example.

  • So I live in Seattle.

  • And one of the best things to do on the weekend--

  • grab a group of friends and head out to the hills

  • to hit the slopes.

  • Let's use that as our example today.

  • Luckily, all of us are using Android Auto in the car.

  • And we can start to-- we can interact with it by voice,

  • keeping our hands on the wheel and our eyes on the road.

  • But we need to coordinate things, like breakfast, gas,

  • and just our general progress.

  • When Android Auto started supporting messaging,

  • there wasn't a standard way to do messaging notifications

  • on Android.

  • We introduced Car Extender helper class

  • for one-on-one conversations.

  • But Android notifications have come a long way since then.

  • MessagingStyle is a newer, standard helper class

  • for generating large-format notifications that

  • include multiple back-and-forth messages of varying types

  • between any number of people.

  • You should already be using it to write rich notifications

  • on mobile devices today.

  • And enabling Android Auto support

  • is a few short changes away from that.

  • So let's take a look at some code.

  • So here's Stephan asking, which run are we going to hit first?

  • All right, we set that up in our MessagingStyle as the message.

  • We set our conversation title, Ski Trip.

  • And since it's a group conversation,

  • we set that to be true.

  • Next, we set up our reply action.

  • We use a semantic action, which is new to Messaging Style.

  • This allows Android Auto and the Google Assistant

  • to know what they should be sending to the pending intent.

  • After the Google Assistant has recognized your voice

  • and composed your reply, it can launch the messaging app

  • to send that reply.

  • Next, we'll create a Mark As Read action.

  • You can imagine a scenario where I'm in the car,

  • and I listen to my message, but I don't really--

  • I'm not really ready to reply yet.

  • This gives the messaging app a callback

  • to say, oh, the user read this.

  • Mark it as read and let other participants

  • in the conversation know.

  • Finally, we bring all that together

  • in a standard way with Android notifications.

  • We had our reply action, our MessagingStyle,

  • and our Mark As Read action.

  • And the Mark As Read action won't show up

  • in the standard Android UI.

  • And we can see the final result. Our conversation title

  • is set up.

  • The group messaging icons are all

  • set up from the notification.

  • And then Assistant and Android Auto

  • know that you can reply by voice.

  • And even if you just listen to the message,

  • we can tell the other participants

  • in the conversation that they've seen it.

  • So now that we've coordinated with everyone,

  • we've figured out where we're going,

  • we want to listen to something on the way

  • out to the mountains, all right?

  • Media in the car is one of the core user experiences.

  • And getting drivers access to their content

  • should be front and center.

  • Now, for media apps to integrate with Android Auto,

  • they have to implement two services.

  • The MediaBrowserService provides a tree

  • of playable and browsable items.

  • And browsable items are basically

  • folders to help apps organize their content so they're not

  • returning a giant list of songs or podcasts.

  • Once a user has picked something playable from the Browse tree,

  • the Media Session Service, which the app implements,

  • is used to start music and to provide metadata and controls

  • for what's currently playing.

  • You can see, in this example, the app

  • supports play, pause, skip to next, skip previous.

  • And there's also a mechanism for setting up custom actions--

  • things like a 30-second skip.

  • Once a media app has implemented these two services,

  • the Google Assistant just works out of the box.

  • They say, hey, Google, play my ski jams.

  • The Google Assistant will recognize your voice,

  • issue the query, and music starts playing right away.

  • What we're introducing today for our in-app searching is

  • the ability to implement an extra function

  • on the MediaBrowserService to get those in-app results--

  • MediaBrowserService on search.

  • In this case, the app has surfaced my ski jams from 2018,

  • as well as my playlist from my skiing trip last year.

  • Awesome.

  • Now, let's look at the code to make this happen.

  • So for apps which already support Android Auto,

  • this is actually really familiar.

  • You have a function which has issued

  • the query, an extras bundle, and a destination

  • for the result. Let's break it down.

  • First off, apps should just return an empty list

  • if they can't support the query, OK?

  • If the thing is like an empty query,

  • just return an empty list.

  • Normally, queries actually require

  • a network call or a database fetch.

  • And so if that's the case, and you

  • want to do work on an extra-- on a different thread,

  • detach the results, do the work on that other thread,

  • and then, when you're ready, send the results

  • back to Android Auto.

  • I want to mention that these code snippets actually

  • come from the Universal Music Player, an open-source media

  • app published by Google on GitHub.

  • It can easily be cloned, compiled,

  • and it's a great reference for creating a media

  • app across Android Auto and other surfaces.

  • So now, we've got our search results--

  • our Ski Trip 2018, 2017, and Ski Jams.

  • Notice that it returned two playlists, as well

  • as some albums.

  • It would be really nice if Android Auto could group those.

  • We have a way to do that, though.

  • In this function, we're creating media items

  • for sending back to Android Auto.

  • And it's very easy to annotate immediate item

  • with a group heading.

  • Android Auto will look at successive media items,

  • and if they're in the same category,

  • will group them together.

  • So if we annotate our Ski Jams with playlist,

  • and our albums with albums, Android Auto groups them

  • and shows that for you, regardless

  • of screen size and surface.

  • We're also adding a couple more annotations,

  • as Lauren mentioned.

  • Here, I'm showing the explicit annotation.

  • It's great.

  • I'm in the car.

  • I got my family.

  • I don't want that explicit song to come up.

  • Also, we're adding a support for downloaded.

  • That way, I'm in the mountains, I don't have good cell

  • coverage, or I don't want to burn my data plan on music,

  • I have a chance to pick the right playlist.

  • Android Auto shows them right with the content.

  • Looks like Ski Trip 2018 is the right playlist for my trip.

  • There's one more function that needs

  • updating to take advantage of these new features.

  • When the MediaBrowserService starts,

  • it provides Android Auto with a media route and extras.

  • In order for search and bringing content out of a drawer

  • to be enabled, you'll need to add a couple of extras

  • to let Android Auto know that you support these features.

  • Now, Lauren introduced the concept

  • of bringing content out and being able to show things

  • as grids or lists.

  • And by default, Android Auto will

  • show browsable items, the folders,

  • as lists, because they generally have an icon.

  • And they'll show content, or playable items,

  • as grids, because they're usually much richer

  • and have a much more detailed artwork.

  • But there are times when it's better to switch that around.

  • So for instance, let's say you have a podcast up.

  • In that case, the podcasts, which are browsable items,

  • have a much richer artwork, right?

  • But all the episodes, which share the same artwork,

  • you want to see more about their detail in a list format.

  • We're giving you the ability to choose that

  • by adding an extra hint in your on route so that you

  • can switch the order around and choose grids or lists depending

  • on the content in your media app.

  • So to sum up, I've shown code samples

  • for MessagingStyle, MediaBrowserService, onSearch,

  • specifying additional item metadata,

  • adding content browsing, and search hints.

  • I'm excited to see developers access

  • these features in the future.

  • And look for our documentation later in the summer.

  • Now, please welcome Dean up to talk about tools

  • for Android Auto development.

  • [APPLAUSE]

  • DEAN HARDING: Thanks, Rasekh.

  • Hi, everyone.

  • So as Rasekh mentioned, I'm here to talk to you

  • about the tools we provide for developing and testing

  • your media and messaging apps, and also

  • to give you some hints and tips to help you

  • make the most of the platform.

  • The first thing I want to talk about is the Desktop Head Unit.

  • This tool is ideal for testing both your messaging and media

  • apps, as it will render your apps exactly the same

  • as you'd see them in production.

  • And just as importantly, it allows

  • you to interact with the Assistant,

  • just like in a real car.

  • You get the Desktop Head Unit as part of the Android SDK.

  • Just select it from the Download Manager.

  • The instructions for running the Desktop Head Unit

  • are on the developer site, but it's fairly easy.

  • Just start the Head Unit Server from Android Auto's developer

  • menu on the phone.

  • You get that by going to About, then tapping 10 times

  • on the About Android Auto header to enable developer mode.

  • Then, choose Start Head Unit Server from the overflow menu

  • that you can see here.

  • Plug your phone into a USB port on the computer

  • and launch the Desktop Head Unit.

  • From there, you can see how Android Auto will

  • respond to your app's notifications,

  • and also, how your media app will appear in an actual car.

  • But if you're developing a media app,

  • I encourage you to check out the Android Media Controller, which

  • is an open-source app that we have hosted on GitHub.

  • It will connect to your app's media session and media browse

  • service and shows the information

  • your app is presenting to Android

  • Auto in a nice semantic format.

  • If you're whitelisting to block apps other than Android Auto

  • from accessing your browse tree, it

  • would probably be a good idea to either add the media

  • controller to the whitelist or disable the whitelist while

  • testing.

  • Rasekh also briefly touched on the Universal Media Player.

  • But I wanted to reiterate that we

  • have this great, comprehensive sample media

  • app available on GitHub.

  • It gives you a canonical implementation

  • of a media app, not only on Android Auto,

  • but also on all our other services, such as Wear and TV.

  • Let's get into some code now.

  • The first bit of code I wanted to talk about

  • was the standard actions that your app returns

  • as part of the playback state.

  • You should try to make sure your app supports

  • the standard actions defined in PlaybackStateCompact,

  • such as ACTION_SKIP_TO_NEXT and ACTION_REWIND.

  • By using the standard actions, you not only

  • have a great integration with Android Auto,

  • but you also get Assistant integration

  • with those actions for free--

  • actions like, OK, Google, skip tracks.

  • And as we bring Android Auto to more surfaces,

  • it may not be the case that those custom actions appear

  • in the same place they do today.

  • But you can be sure the standard actions are kept in a place

  • where it makes the most sense.

  • You can use the media controller app

  • to see what standard actions you've implemented,

  • and also to see what's available.

  • You can see here that we have an app that

  • does not implement a standard forwards, backwards action,

  • but has instead chosen to implement those actions

  • as custom actions.

  • Now, if you were to look at this app in the Desktop Head Unit,

  • you might not necessarily know that there's anything wrong.

  • Because of the way we render the custom actions,

  • everything looks OK.

  • But by implementing those actions as standard actions,

  • like this, we can leave the custom actions

  • for truly custom functionality.

  • We've done a lot of research with users

  • and found that users do not want to have

  • to browse while driving.

  • Here are a few quotes from some of our research sessions,

  • where users talk about some of the issues

  • that they have with custom search and browse.

  • Users typically want to get in and go without much fuss,

  • and this is a great opportunity for you

  • to provide some additional value to your users

  • by giving them easy access to the playlists they like

  • or to recommend new content that they may not

  • have known about otherwise.

  • So I would suggest that you prioritize

  • surfacing things in the browse tree with items most relevant

  • to driving at the top.

  • Rasekh showed you earlier some of the things

  • we're doing to bring content out of the drawer

  • and put it front and center.

  • And you'll definitely want that first page of content

  • to be the most useful.

  • Now, that's not to say you can't include

  • all the user's playlists, or whatever, in the browse tree.

  • Just keep in mind that the first few items on your home page

  • should be the most relevant to the task of driving.

  • A corollary to that would be to keep your browse tree

  • shallow, no more than two or three levels deep.

  • In fact, to make the most of the new design we've shown you,

  • a two-level-deep browse tree is ideal,

  • because then, your users will be able to get

  • to their favorite music or podcasts with a single tap.

  • You can use the onSearch method that Rasekh described earlier

  • to allow users to search for specific things,

  • like a particular song or a particular artist.

  • One of the challenges we have in Android Auto

  • is that it is used on devices with many different screen

  • sizes and resolutions.

  • Your app isn't necessarily going to know,

  • until the moment it's plugged into a car, what

  • the resolution of the screen it's displayed on is,

  • which means that it's difficult to predict

  • what resolution your icons need to be to look right

  • on any particular screen.

  • You can see here, this star icon is too low resolution

  • for this display, and it really looks out

  • of place with the rest of the icons.

  • So package your icons in the vector graphics format,

  • rather than a bitmap format.

  • Vector drawables have been supported natively in Android

  • since API level 21, which, coincidentally,

  • is the version of Android that Android Auto support was

  • introduced.

  • So there's no reason not to use the native vector format.

  • You can see here an example of the star icon

  • from before as a vector graphic.

  • And no matter how big I make the icon,

  • it still has nice, smooth edges.

  • As an added bonus, the file size of this icon

  • is really small, especially compared

  • to having multiple bitmaps at different resolutions.

  • Don't forget, you can use Android Studio's Vector Asset

  • tool to convert your SVGs to the native Android format.

  • While we're on the topic of icons,

  • you should prefer using the URI-based methods

  • for passing us your media, rather than

  • the drawable-based methods.

  • This example shows returning one of your built-in resources

  • as a URI rather than a drawable.

  • Using URIs allows us to case your resources

  • and to only allocate memory for the items

  • that we are actually physically displaying.

  • If the user never scrolls down to the fourth page,

  • there's no need to allocate memory for the items

  • down there.

  • I also wanted to briefly touch on

  • something we've seen with ad-supported apps.

  • Typically, the adds will include some call

  • to action that may not make sense when running in the car.

  • For instance, they might say, tap the screen to learn more,

  • or click here, or something along those lines.

  • If you're running inside Android Auto,

  • I recommend adjusting your messaging

  • so that it's not confusing for people not actually using

  • your main app's UI.

  • And lastly, the process of actually getting your app

  • onto the Play Store--

  • once you've added this metadata snippet to your manifest,

  • and you've uploaded your app to the Play Store,

  • it will need to be reviewed against our Driver Distraction

  • Guidelines.

  • This is a fairly complicated process,

  • but the guidelines for ensuring a smooth review

  • are documented in the developer center at this link.

  • If our reviewers find issues, you'll be notified by email

  • and will be able to resubmit an updated

  • application for re-review.

  • So I've gone over a few things we've

  • learned over the years developing for Android Auto.

  • We've got a great resource in the Media Controller

  • for testing media apps.

  • And don't forget to check out the Universal Media

  • Player for a comprehensive example implementation.

  • Use the standard actions where it makes sense,

  • and leave custom actions for things

  • that are actually custom.

  • Surface the important actions at the top in browse.

  • And use search for finding specific content,

  • like a particular song or a particular album.

  • Keep the browse tree shallow, no more than two

  • or three levels deep.

  • Use vector graphics for icons.

  • And use the URI-based methods rather

  • than sending raw bitmaps.

  • And finally, be aware of the surface you're

  • playing on for ads.

  • And now, I'd like to hand it back over

  • to Patrick for our wrap-up.

  • [APPLAUSE]

  • PATRICK BRADY: Yeah, thanks.

  • Thanks, Dean.

  • So today, we showed you how we're

  • working to make Android the platform for developers

  • in automotive and how you can develop

  • your apps on that platform.

  • We also showcased a new design for Android Auto in your apps

  • across surfaces, from old cars to new, and new developer

  • APIs that enable your apps to take advantage

  • of these new designs and features,

  • including MessagingStyle for group messaging and custom

  • actions, media browse enhancements

  • to bring your content forward and annotate it with rich media

  • metadata, and media in-app search to help your users

  • find the content they're looking for across your catalog.

  • Of course, that's just a sneak preview

  • of all the developer resources.

  • If you'd like more information to help you update your apps,

  • please visit the Android Auto Developer site

  • at developer.android.com/auto.

  • And I'd also encourage you to take a look at the Universal

  • Media Player and Android Media Controller examples

  • that Rasekh and Dean mentioned, which

  • are freely available as open-source software on GitHub.

  • And while you're here, you can also

  • stop by the Android Team office hours, which

  • are happening again on Thursday at 2:30 PM,

  • to chat with the Android engineers and business

  • development teams and ask them questions directly.

  • But if you really want to see these things in action,

  • please come and check out the Android Auto Sandbox,

  • which is just around the corner, where you can see

  • the new Android Auto design.

  • And I promise you, it's not as janky.

  • It seems like we were having some AV issues

  • with the animations earlier.

  • But you can see the new design operating fluidly

  • in a new Range Rover Velar, on a beautiful, wide screen,

  • showing simultaneous maps and media on the UI

  • at the same time.

  • It's really, we think, a fantastic experience.

  • You can also find the Google In-Car Concept

  • that Lauren talked about, which is showing the default

  • experience in Android that we're making

  • available as open-source software in Android

  • P, and of course, the latest in-car experience

  • from our collaboration with Volvo

  • in the new Android-powered Sensus Connect system,

  • running the Google Assistant, Google Maps, and the Google

  • Play Store.

  • Last but not least, as with every session at I/O,

  • we want to--

  • we value your feedback, and we want

  • to hear from you so we can make our sessions better every year.

  • So please grab a browser and swing by google.com/io/schedule

  • to fill out a short survey when you have time and leave

  • your feedback.

  • Thanks very much, and have a great I/O.
