  • MAGNUS HYTTSTEN: Welcome to release 7.8

  • of Google Play Services.

  • You are here because you want to build better apps,

  • and that's exactly what Google Play

  • Services is all about-- allowing you to build better apps.

  • Let's get started with the highlights in this release,

  • because we are excited to present some really

  • new cool stuff.

  • Let's start it off with-- yeah, that's right.

  • We have a new API.

  • Let's welcome the Mobile Vision API with a round of applause.

  • [APPLAUSE]

  • The new Vision API enables you to build really amazing things.

  • One part of it is the Faces API that

  • allows you to detect faces and different characteristics

  • of faces in images or even in real time video.

  • So here, for example, are some of my friends working

  • at Google.

  • And as you can see, the location of all of their faces

  • has been detected by the Faces API.

  • And faces can be detected in different angles too.

  • It doesn't have to be oriented straight forward.

  • It can, for example, be tilted and turned

  • and all the other possible positions

  • that you can see here, but that I don't have time

  • to perform with my own head.

  • And once a face has been detected,

  • you retrieve the different landmarks

  • in the face-- for example, the location

  • of the eyes, the mouth, the cheeks, the nose

  • space, and even the ear tips.

  • How cool is not that?

  • And believe it or not, you get even more with this one

  • is my favorite.

  • You can detect whether certain facial characteristics

  • is present using classifications-- for example,

  • if an eye is closed or open, or how

  • much smiley-ness the face has.

  • For example, this here would be close to zero,

  • but this one would be a smiley-ness close to one.

  • And remember, since the Faces API

  • can detect these things in real time video,

  • you can create really cool apps.

  • Let's look at one in real life.

  • So here I am, sitting on the sofa,

  • trying out an app that uses the Faces

  • API to detect if my eyes are open and whether I'm smiling

  • or not.

  • Let's try it out, starting with eyes closed and not smiling.

  • FACES API: I detect that your eyes are closed.

  • Please open your eyes.

  • That's beautiful.

  • You should always keep your eyes open.

  • Now wipe that grumpy grin off your face and smile instead.

  • Lovely.

  • Smiling is good for you.

  • You should always smile.

  • MAGNUS HYTTSTEN: Amazing.

  • As you may think now that that was it for the Vision API,

  • but it's not.

  • You get even more, because in addition to the Faces API,

  • the Vision API also has a Barcode API.

  • So pretty much in the same way that you can detect faces

  • in images or videos, you can also detect barcodes.

  • So go out there and create some great apps with the Vision API.

  • And remember, it has both a Faces API, as well as a Barcode

  • API.

  • And it can detect things in images as well as

  • in real time video.

  • In this release, we also have announcements for Google Cloud

  • Messaging where we have expanded notification

  • to support localization.

  • So you can now construct notification messages

  • that will be displayed using the locale of the device it

  • is sent to.

  • And to get ready for the Android M release,

  • we've added high and normal priority to GCM messaging.

  • This allows you to set messages that need immediate attention

  • to high priority-- for example, a chat message

  • alert or an incoming voice call alert.

  • This brings us to-- yeah, that's right.

  • It's time to announce another new API in this release.

  • Let's welcome the Nearby Messages API

  • with a round of applause.

  • [APPLAUSE]

  • Nearby Message is a cross-platform API

  • to find and communicate with mobile devices and beacons

  • based on proximity.

  • You may recall that in a previous version,

  • we introduced a Nearby Connections

  • API that allows you to discover other devices

  • and create connections, allowing them

  • to communicate in real time.

  • Great for local multi-player gaming

  • where players can use their own device

  • as a remote control connecting to a central game server.

  • And now we're extending the Nearby API

  • with the introduction of Nearby Messages.

  • Nearby Messages allows your users

  • to find devices and share messages with them

  • through a Publish and Subscribe API.

  • This allows you to build apps with rich local interactions

  • between devices.

  • For example, to collaborate on content, forming a group,

  • vote on something, or broadcasting a resource.

  • So how does Nearby Messages send these messages?

  • Well, first of all, it can use the Bluetooth or Wi-Fi signals

  • to connect and exchange data.

  • But it goes even beyond that.

  • Ultrasonic sounds can also be used to transmit messages.

  • That's right.

  • Sounds that we humans cannot hear and that contains

  • the information.

  • That's pretty, pretty amazing stuff.

  • And there's even more.

  • This API is also used to pick up information from beacons.

  • So beacons are these devices you can put up that broadcast

  • information through the Nearby Messages API.

  • And any device that is close by can then pick this information

  • up and act on it.

  • And that's it for this release of Google Play Services.

  • But be sure to check out these resources as well.

  • Now you have some work to do to use these fantastic

  • APIs to build better apps.

  • That's right.

  • Go out there and create some great apps.

  • And don't forget to tell us all about it.
