Google Play services 7.8 - Let’s see what’s Nearby!

Posted by Magnus Hyttsten, Developer Advocate, Play services team

Today we’ve finished the roll-out of Google Play services 7.8. In this release, we’ve added two new APIs. The Nearby Messages API allows you to build simple interactions between nearby devices and people, while the Mobile Vision API helps you create apps that make sense of the visual world, using real-time on-device vision technology. We’ve also added optimization and new features to existing APIs. Check out the highlights in the video or read about them below.

Nearby Messages

Nearby Messages introduces a cross-platform API to find and communicate with mobile devices and beacons, based on proximity. Nearby uses a combination of Bluetooth, Wi-Fi, and an ultrasonic audio modem to connect devices. And it works across Android and iOS. For more info on Nearby Messages, check out the documentation and the launch blog post.

Mobile Vision API

We’re happy to announce a new Mobile Vision API. Mobile Vision has two components.

The Face API allows developers to find human faces in images and video. It’s faster, more accurate and provides more information than the Android FaceDetector.Face API. It finds faces in any orientation, allows developers to find landmarks such as the eyes, nose, and mouth, and identifies faces that are smiling and/or have their eyes open. Applications include photography, games, and hands-free user interfaces.

The Barcode API allows apps to recognize barcodes in real-time, on device, in any orientation. It supports a range of barcodes and can detect multiple barcodes at once. For more information, check out the Mobile Vision documentation.

Google Cloud Messaging

And finally, Google Cloud Messaging - Google’s simple and reliable messaging service - has expanded notification to support localization for Android. When composing the notification from the server, set the appropriate body_loc_key, body_loc_args, title_loc_key, and title_loc_args. GCM will handle displaying the notification based on current device locale, which saves you having to figure out which messages to display on which devices! Check out the docs for more info.

And getting ready for the Android M release, we've added high and normal priority to GCM messaging, giving you additional control over message delivery through GCM. Set messages that need immediate users attention to high priority, e.g., chat message alert, incoming voice call alert. And keep the remaining messages at normal priority so that it can be handled in the most battery efficient way without impeding your app performance.

SDK Now Available!

You can get started developing today by downloading the Google Play services SDK from the Android SDK Manager.

Connect With the World Around You Through Nearby APIs

Mobile phones have made it easy to communicate with anyone, whether they’re right next to you or on the other side of the world. The great irony, however, is that those interactions can often feel really awkward when you're sitting right next to someone.

Today, it takes several steps -- whether it’s exchanging contact information, scanning a QR code, or pairing via bluetooth -- to get a simple piece of information to someone right next to you. Ideally, you should be able to just turn to them and do so, the same way you do in the real world.

This is why we built Nearby. Nearby provides a proximity API, Nearby Messages, for iOS and Android devices to discover and communicate with each other, as well as with beacons.

Nearby uses a combination of Bluetooth, Wi-Fi, and inaudible sound (using the device’s speaker and microphone) to establish proximity. We’ve incorporated Nearby technology into several products, including Chromecast Guest Mode, Nearby Players in Google Play Games, and Google Tone.

With the latest release of Google Play services 7.8, the Nearby Messages API becomes available to all developers across iOS and Android devices (Gingerbread and higher). Nearby doesn’t use or require a Google Account. The first time an app calls Nearby, users get a permission dialog to grant that app access.

A few of our partners have built creative experiences to show what's possible with Nearby.

Edjing Pro uses Nearby to let DJs publish their tracklist to people around them. The audience can vote on tracks that they like, and their votes are updated in realtime.

Trello uses Nearby to simplify sharing. Share a Trello board to the people around you with a tap of a button.

Pocket Casts uses Nearby to let you find and compare podcasts with people around you. Open the Nearby tab in Pocket Casts to view a list of podcasts that people around you have, as well as podcasts that you have in common with others.

Trulia uses Nearby to simplify the house hunting process. Create a board and use Nearby to make it easy for the people around you to join it.
