The latest Android and Google Play news for app and game developers.
Android Things enables you to build and maintain IoT devices at scale. We recently released Android Things 1.0 with long-term support for production devices, so you can easily take an IoT device from prototype to commercial product.
We packed Google I/O this year with Android Things content to inspire and empower the developer community, from talks and codelabs to interactive demos and a scavenger hunt. Here's a closer look at the fun stuff we had on display that you won't see on the shelves of retail stores.
We introduced a handful of new interactive Android Things demos across I/O, showcasing the AI and ML capabilities of the platform, so if you didn't get an opportunity to attend this year, here's a few of our favorites-- perfect for exploring from wherever you are in the world!
Smart Flowers: Flos Mobilis
What do you get when you combine machine learning, Android Things and robotics? Flos Mobilis, a continuum robot where each flower is backed by an i.MX7D development board and a camera to run an embedded neural net model that controls the motion of the flower. This is all done offline with no data stored or transmitted.
Smart Flowers: Flos Affectus
What if a robot could respond to the way you feel? Flos Affectus is a cluster of robotic flowers that "bloom" and "un-bloom" depending on the expression detected on the user's face. The 4 broad expressions Flos Affectus is trained to detect are: happy, sad, angry, surprised. Using a camera embedded in the head of the alpha flower, the flower cluster is able to detect the user's face and infer the facial emotion. The flower cluster runs offline with no data stored or transmitted and demonstrates movement capabilities and on-device machine learning models.
Rosie the Android
Initially designed by a team of Google engineers for the annual Grace Hopper conference, Rosie the Android is a 5 foot selfie-taking Android, complete with machine-learning capabilities. Inspired by Rosie the Riveter, she's a fully controllable robot that can take photos, respond to commands, wheel around and interact with those around her.

Smart Projector
Smart Projector is built on Lantern, an Android Things project exploring the relationship between surfaces and content — augmenting real-world objects and environments with glanceable, meaningful data. It leverages the Google Experiments project known as Quick Draw, using the world's largest doodling data set that has been shared publicly to help with machine learning research.
To learn more about Lantern or to start building your own, start here.
3D Printer
This modified Printrbot Smalls 3D Printer uses a real-time subsystem that showcases the flexibility of Android Things-- a microcontroller does the low-latency motor control, while Android Things handles OpenGL rendering. By keeping most of the logic on a high-level platform like Android you make development and debugging much easier, thanks to Android's great tooling.
The future of 3D printing? Making real-time control as easy and portable as the rest of Android Things.
Phew! That was just the tip of the demo iceberg. With so many demos and so many ways to use Android Things, it's easy to start imagining all the things you can build! At I/O, we helped a lot of developers get started building their first Android Things device using the Android Things Starter Kit. We're making these codelabs available, so you can get to them whenever you need, or build your own.

Posted by Sai Deep Tetali, Software Engineer, Google Play Protect
At Google I/O 2017, we introduced Google Play Protect, our comprehensive set of security services for Android. While the name is new, the smarts powering Play Protect have protected Android users for years.
Google Play Protect's suite of mobile threat protections are built into more than 2 billion Android devices, automatically taking action in the background. We're constantly updating these protections so you don't have to think about security: it just happens. Our protections have been made even smarter by adding machine learning elements to Google Play Protect.
Google Play Protect provides in-the-moment protection from potentially harmful apps (PHAs), but Google's protections start earlier.
Before they're published in Google Play, all apps are rigorously analyzed by our security systems and Android security experts. Thanks to this process, Android devices that only download apps from Google Play are 9 times less likely to get a PHA than devices that download apps from other sources.
After you install an app, Google Play Protect continues its quest to keep your device safe by regularly scanning your device to make sure all apps are behaving properly. If it finds an app that is misbehaving, Google Play Protect either notifies you, or simply removes the harmful app to keep your device safe.
Our systems scan over 50 billion apps every day. To keep on the cutting edge of security, we look for new risks in a variety of ways, such as identifying specific code paths that signify bad behavior, investigating behavior patterns to correlate bad apps, and reviewing possible PHAs with our security experts.
In 2016, we added machine learning as a new detection mechanism and it soon became a critical part of our systems and tools.
In the most basic terms, machine learning means training a computer algorithm to recognize a behavior. To train the algorithm, we give it hundreds of thousands of examples of that behavior.
In the case of Google Play Protect, we are developing algorithms that learn which apps are "potentially harmful" and which are "safe." To learn about PHAs, the machine learning algorithms analyze our entire catalog of applications. Then our algorithms look at hundreds of signals combined with anonymized data to compare app behavior across the Android ecosystem to find PHAs. They look for behavior common to PHAs, such as apps that attempt to interact with other apps on the device, access or share your personal data, download something without your knowledge, connect to phishing websites, or bypass built-in security features.
When we find apps exhibit similar malicious behavior, we group them into families. Visualizing these PHA families helps us uncover apps that share similarities to known bad apps, but have yet remained under our radar.
After we identify a new PHA, we confirm our findings with expert security reviews. If the app in question is a PHA, Google Play Protect takes action on the app and then we feed information about that PHA back into our algorithms to help find more PHAs.
So far, our machine learning systems have successfully detected 60.3% of the malware identified by Google Play Protect in 2017.
In 2018, we're devoting a massive amount of computing power and talent to create, maintain and improve these machine learning algorithms. We're constantly leveraging artificial intelligence and our highly skilled researchers and engineers from all across Google to find new ways to keep Android devices safe and secure. In addition to our talented team, we work with the foremost security experts and researchers from around the world. These researchers contribute even more data and insights to keep Google Play Protect on the cutting edge of mobile security.

The Kotlin language lets you create apps in less time, writing less code, and with fewer errors.
This modern object-oriented language offers a strong type system, type inference, null safety, properties, lambdas, extensions, coroutines, higher-order functions, and many other features. Kotlin is so concise that you can create complete data classes with a single line of code.
Kotlin is officially supported for building Android apps, fully interoperates with the Java programming language and libraries, and is included with IntelliJ and Android Studio.
In this course you will learn everything you need to program in Kotlin, including:
You'll learn how to use extension functions to add helpful functionality to existing classes.
Extend built-in types:
fun Int.print() = println(this) 5.print() // prints 5
Extend Android classes:
fun Context.toast(text: CharSequence, duration: Int = Toast.LENGTH_SHORT): Toast { return Toast.makeText(this, text, duration).apply { show() } } toast("Hello Toast")
Extend your own classes:
class AquariumPlant( val color: String) fun AquariumPlant.print() = println("Pretty Aquarium Plant") val plant = AquariumPlant("green") plant.print() // prints -> Pretty Aquarium Plant
When you've completed the course, you will be able to create programs in Kotlin, taking advantage of the features and capabilities that make Kotlin unique.

Today's customers want to get things done faster than ever, whether they're ordering groceries or shopping for a new pair of shoes. With Google Pay, we want to ensure checkout doesn't slow them (or your conversions) down, while enhancing the customer experience at every step of the way.
Last week at Google I/O, we announced some exciting new features that do just that. We also shared the latest ways developers can use Google Pay to offer the best experiences at checkout and beyond—all available for free with our APIs. Here are some of the highlights and how you can make the most of them.
We've started rolling out support for checking out with Google Pay regardless of your browser or device. This means customers can pay with Google Pay on most major browsers from any device.
Enabling this functionality within your apps and sites is simple. Watch Google Pay software engineer Tony Chen do a website integration live on stage, then try it yourself using our developer docs.
But making checkout easier for your customers doesn't just apply to how they pay. Chrome Autofill helps customers fill in forms automatically, so they can speed through the entire checkout process without getting bogged down by typing. To ensure your shoppers are getting the fastest checkout experience with Chrome Autofill, we recommend you check out our new best practices guide.
We'll also be making it easier for customers to manage their payment methods in Google Pay by adding this functionality to our iOS and desktop experiences as well. The new functionality will allow people to add cards and see transactions whenever and wherever it's most convenient for them, giving you access to a new group of customers who will be able to use Google Pay within your apps and sites. It also means that customers who add cards from a laptop can use those cards with Google Pay on an iOS device. (Try it for yourself at g.co/pay/demo.)
This new functionality will be launching soon, and you can learn more about it in our Build with Google Pay session.
Building off our newly-launched support for prepaid transit passes, we're now also supporting a new way for you to save and manage passes through our Google Pay API for Passes. This lets you create mobile event tickets and boarding passes that your customers can save to the Google Pay Android app. We've piloted this feature with Southwest, Fortress GB, and Ticketmaster, with more partners coming soon. Want to get on board? Sign up for more information.
Actions on Google lets developers engage billions of users across the Google Assistant and soon Google Search, Android, and other surfaces by developing Actions and linking them with our ever-growing intents catalog. One of our sessions shows you how you can enable Google Pay in your Actions so your customers can make purchases with their Assistant across multiple surfaces, including mobile devices, Google Home, and soon, Smart Displays. Transactions are now available in Australia, Canada, Japan, France, Germany, the United States, and the United Kingdom. (We'll be bringing them to Brazil, India, Italy, and Spain soon.)
Plus, we're starting a developer preview where you can now enable transactions to sell digital content on the Google Assistant. That includes in-app purchases, subscriptions, games, experiences, and premium content.
We can't wait to see all of the creative ways you use Google Pay to amplify your business and build better checkout experiences for your customers. Be sure to check out all of our I/O sessions for more ideas, tools, and tips. In the meantime, we'll be hard at work on new features to keep making Google Pay the best experience possible—for you and your customers.

Android P Beta available at android.com/beta
As Android continues to evolve, each new release of the OS brings new features, new user experiences, and better security. It is important that these new releases find their way to mobile devices as fast as possible.
Yesterday, we announced that the following devices, in addition to Pixel and Pixel 2, now support Android P Beta: Sony Xperia XZ2, Xiaomi Mi Mix 2S, Nokia 7 Plus, Oppo R15 Pro, Vivo X21, OnePlus 6 and Essential PH‑1. Android P Beta provides an opportunity for developers and early adopters around the world to try the latest Android release, test their apps, and provide feedback.
In this post, we provide an update to Project Treble and the technology that allowed us to bring Android Beta to more phones this year.
Bringing the new Android release quickly to the hands of users takes a combined effort between Google, silicon manufacturers (SM), device manufacturers (OEMs), and carriers. This process is technically challenging and requires aligning the schedules between our industry partners.
To reduce the technical difficulties, we launched Project Treble as part of Android Oreo.
Next, to capitalize on the foundation we built, we collaborated closely with the silicon manufacturers, where the journey of making an Android device always begins.
Any device with the latest version of Android must be based on an SoC with the proper software support for it. This software, commonly referred to as the Board Support Package (BSP), contains not only the chip-specific vendor implementation, but also all of the Android Open Source Project (AOSP) and pieces of the framework that are missing from AOSP itself (e.g., carrier-specific telephony functionality).
These BSPs are the starting point for all device launches. OEMs adapt the vendor implementation to their hardware and add their own custom framework components.
While silicon manufacturers always want the latest version of Android in their BSPs, the costs have been prohibitive. By making it possible for newer AOSP frameworks to run on older, already-released vendor implementations, Project Treble dramatically reduces the need for continuous investment in older silicon to support each Android release. Silicon manufacturers have to do all this work just once, rather than every time there is a new release of Android.
However, that first time still has to happen. Below is a chart, which illustrates the effort the various actors expend over time as they go through each release. You can think of it as code churn or bug count over time.
The chart shows how there is very little time in the year for Google, silicon manufacturers, and the OEMs to all this work. Any overlap between phases causes code churn and introduces significant schedule risk. For OEMs who target the holiday season, it is often safer to launch on an older BSP with a year-old or even older Android version. This dynamic has been at the heart of the slow uptake of the latest Android release, even on flagship devices.
To solve this, we've worked closely with Qualcomm, MediaTek and Samsung Electronics’ System LSI Business to co-develop their BSPs, starting with Android P. Their BSPs are now ready for Android P on a much-accelerated schedule, reducing the overall effort significantly. These silicon manufacturers are now able to provide a stable and high-quality release much earlier than before, allowing OEMs to bring the latest innovations of Android to their customers across the globe.
This is an important step in accelerating the adoption of Android releases that bring numerous benefits to our partners, users, and Android developers. We look forward to seeing many more partners launch or upgrade devices to Android P.
