While most chatbots respond to user requests in a synchronous way, there are scenarios when bots don't perform actions based on an explicit user request, such as for alerts or notifications. In today's DevByte video, I'm going to show you how to send messages asynchronously to rooms or direct messages (DMs) in Hangouts Chat, the team collaboration and communication tool in G Suite.
What comes to mind when you think of a bot in a chat room? Perhaps a user wants the last quarter's European sales numbers, or maybe, they want to look up local weather or the next movie showtime. Assuming there's a bot for whatever the request is, a user will either send a direct message (DM) to that bot or @mention the bot from within a chat room. The bot then fields the request (sent to it by the Hangouts Chat service), performs any necessary magic, and responds back to the user in that "space," the generic nomenclature for a room or DM.
Our previous DevByte video for the Hangouts Chat bot framework shows developers what bots and the framework are all about as well as how to build one of these types of bots, in both Python and JavaScript. However, recognize that these bots are responding synchronously to a user request. This doesn't suffice when users want to be notified when a long-running background job has completed, when a late bus or train will be arriving soon, or when one of their servers has just gone down. Recognize that such alerts can come from a bot but also perhaps a monitoring application. In the latest episode of the G Suite Dev Show, learn how to integrate this functionality in either type of application.
From the video, you can see that alerts and notifications are "out-of-band" messages, meaning they can come in at any time. The Hangouts Chat bot framework provides several ways to send asynchronous messages to a room or DM, generically referred to as a "space." The first is the HTTP-based REST API. The other way is using what are known as "incoming webhooks."
The REST API is used by bots to send messages into a space. Since a bot will never be a human user, a Google service account is required. Once you create a service account for your Hangouts Chat bot in the developers console, you can download its credentials needed to communicate with the API. Below is a short Python sample snippet that uses the API to send a message asynchronously to a space.

Webhooks are a quick and easy way to send messages into any room or DM without configuring a full bot, i.e., monitoring apps. Webhooks also allow you to integrate your custom workflows, such as when a new customer is added to the corporate CRM (customer relationship management system), as well as others mentioned above. Below is a Python snippet that uses an incoming webhook to communicate into a space asynchronously.
import requests import json URL = 'https://chat.googleapis.com/...&thread_key=T12345' message = {'text': 'Hello world!'} requests.post(URL, data = json.dumps(message))Since incoming webhooks are merely endpoints you HTTP POST to, you can even use
curl to send a message to a Hangouts Chat space from the command-line:curl \ -X POST \ -H 'Content-Type: application/json' \ 'https://chat.googleapis.com/...&thread_key=T12345' \ -d '{"text": "Hello!"}'To get started, take a look at the Hangouts Chat developer documentation, especially the specific pages linked to above. We hope this video helps you take your bot development skills to the next level by showing you how to send messages to the Hangouts Chat service asynchronously.

Flutter Release Preview 1: Live from GMTC in Beijing
Thursday, June 21, 2018
Posted by the Flutter Team at Google
Today at the GMTC front-end conference in Beijing, we announced Flutter Release Preview 1, signaling a new phase of development for Flutter as we move into the final stages of stabilization for 1.0.
Google I/O last month was something of a celebration for the Flutter team: having reached beta, it was good to meet with many developers who are learning, prototyping, or building with Flutter. In the immediate aftermath of Google I/O, we continue to see rapid growth in the Flutter ecosystem, with a 50% increase in active Flutter users. We've also seen over 150 individual Flutter events taking place across fifty countries: from New York City to Uyo, Nigeria; from Tokyo and Osaka in Japan to Nuremberg, Germany.
One common measure of community momentum is the number of GitHub stars, and we've also seen tremendous growth here, with Flutter becoming one of the top 100 software repos on GitHub in May.
The shift from beta to release preview with this release signals our confidence in the stability and quality of what we have with Flutter, and our focus on bug fixing and stabilization.
We've posted a longer article with details on what's new in Flutter Release Preview 1 over at our Medium channel. You can download Flutter Release Preview 1 directly from the Flutter website, or simply run
It's been fun to watch others encounter Flutter for the first time. This article from an iOS developer who has recently completed porting an iOS app to Flutter is a positive endorsement of the project's readiness for real-world production usage:

Announcing Flutter Release Preview 1
Today we're taking another big step forward, with the immediate availability of Flutter Release Preview 1. It seems particularly auspicious to make this announcement in Beijing at the GMTC Global Front-End Conference. China has the third largest population of developers using Flutter, after the USA and India. Companies such as Alibaba and Tencent are already adopting Flutter for production apps, and there is a growing local community who are translating content and adding packages and mirrors for Chinese developers.The shift from beta to release preview with this release signals our confidence in the stability and quality of what we have with Flutter, and our focus on bug fixing and stabilization.

flutter upgrade from an existing installation.It's been fun to watch others encounter Flutter for the first time. This article from an iOS developer who has recently completed porting an iOS app to Flutter is a positive endorsement of the project's readiness for real-world production usage:
"I haven't been this excited about a technology since Ruby on Rails or Go… After dedicating years to learning iOS app dev in-depth, it killed me that I was alienating so many Android friends out there. Also, learning other cross platform frameworks at the time was super unattractive to me because of what was available… Writing a Flutter app has been a litmus test and Flutter passed the test. Flutter is something I feel like I can really invest in and most importantly, really enjoy using."
As we get ever closer to publishing our first release from the "stable" channel, we're ready for more developers to build and deploy solutions that use this Release Preview. There are plenty of training offerings to help you learn Flutter: from I/O sessions to newsletters to hands-on videos to developer shows. We're excited to see what youbuild!

Creating AR Experiences for I/O: Our Process
Wednesday, May 30, 2018
Posted by Karin Levi, Product Marketing, ARCore
A few weeks ago at Google I/O we released a major update to ARCore, Google's AR development platform. We added new APIs like Cloud Anchors, that enable multi-user, collaborative AR experiences and Augmented Images that enable activation of 2D images into 3D objects. All of these updates are going to change the way we use AR today and enable developers to create richer, more immersive AR apps.
With these new capabilities, we decided to put our platform to the test. So we built real experiences to showcase how these all come to life. All demos were presented at the I/O AR & VR sandbox area. We open sourced them to make sure you can see how simple it is to build these experiences. We're pretty happy with how they turned out and would love to share with you some learning and insights from behind the scenes.
Light Board is an AR multiplayer tabletop game where two players on floating game boards launch colored projectiles at each other.
While building Light Board it was important for us to keep in mind who the end users are. We wanted it to be a simple/fun game for developers to try out while visiting the I/O sandbox. The developers would only have a couple minutes to play while passing through, so it needed to allow players (even non-gamers) to pick it up and play with very little setup.
The artwork for Light Board was a major focus. Our mission for the look of the game was to align with the design and decor of I/O 2018. This way, our app would feel like an extension of everything the attendees saw around them. As a result, our design philosophy had 3 goals; bright accent colors, simple graphic shapes and natural physical materials.
On the engineering front we selected the Unity game engine as our dev environment. Unity gives us a couple of important advantages. First, it is easy to get great looking 3D graphics up and running right away. Second, the engine component is already complete, so we could immediately start iterating on gameplay code. As with the artwork, this allowed us to test gameplay options before we made a final decision. Additionally, Unity gave us support for both Android and iOS with only a little extra work.
To handle the multiplayer aspect we used Firebase Realtime Database. We were concerned with network performance at the event, and felt that the persistent nature of a database would make it more tolerant of poor networks. As it turned out, it worked very well and we got the ability to quit and rejoin games for free!
We had a lot of fun building Light Board and we hope people can use it as an example of how easy it can be to not only build AR apps, but to use really cool features like Cloud Anchors. Please check out our open source repo and give Light Board a try!
In March, we released Just a Line, an Android app that lets you draw in the air with your phone. It's a simple experiment meant to showcase the power of ARCore. At Google I/O, we added Cloud Anchors to the app so that two people can draw at once in the same space, even if one of them is using Android and the other iOS.
Both apps were built natively: The Android version was written in Android Studio, and the iOS version was built in xCode. ARCore's Cloud Anchors enable Just a Line to pair two phones, allowing users to draw simultaneously in a shared space. Pairing works across Android and iOS devices, and drawings are synchronized live through a Firebase Realtime Database. You can find the open-source code for iOS here and for Android here.
"Illusive Images" demo is an augmented gallery consisting of 3 artworks, each exploring a different augmented image use case and user experience. As one walks from side to side, around the object, or gazes in a specific direction, 2D artworks are married with 3D, inviting the viewer to enter into the space of the artwork spanning well beyond the physical frame.
Due to the visual design nature of our augmented images, we experimented a lot with creating databases with varying degrees of features. In order to get the best results, we iterated quickly by resizing the canvas for the artwork. We also moved and stretched the brightness and contrast levels. These variations helped to achieve the most optimal image without compromising design intent.
The app was built in Unity with ARCore, with the majority of assets created in Cinema 4D. Mograph animations were imported into Unity as an fbx, and driven entirely by the position of the user in relation to the artwork. An example project can be found here.
To make your development experience easier, we open sourced all the demos our team built. We hope you find this useful! You can also visit our website to learn more and start building AR experiences today.

Left: Design for AR/VR Sandbox at I/O 2018. Right: Key art for Light Board game boards
The artwork was created in Maya and Cinema 4D. We created physically based materials for our models using Substance Painter. Just as continuous iteration is crucial for engineering, it is also important when creating art assets. With that in mind, we kept careful track of our content pipeline, even for this relatively simple project. This allowed us to quickly try out different looks and board styles before settling on our final design.On the engineering front we selected the Unity game engine as our dev environment.

Posted by Mertcan Mermerkaya, Software Engineer
We have great news for web developers that use Firebase Cloud Messaging to send notifications to clients! The FCM v1 REST API has integrated fully with the Web Notifications API. This integration allows you to set icons, images, actions and more for your Web notifications from your server! Better yet, as the Web Notifications API continues to grow and change, these options will be immediately available to you. You won't have to wait for an update to FCM to support them!
Below is a sample payload you can send to your web clients on Push API supported browsers. This notification would be useful for a web app that supports image posting. It can encourage users to engage with the app.
To handle action clicks in your app, you need to add an event listener in the default firebase-messaging-sw.js file (or your custom service worker). If an action button was clicked, event.action will contain the string that identifies the clicked action. Here's how to handle the "
Since different browsers support different parameters in different platforms, it's important to check out the browser compatibility documentation to ensure your notifications work as intended.

You now will receive fun daily photos of fish!", "icon": "firebase-logo.png", "image": "guppies.jpg", "data": { "notificationType": "fishPhoto", "photoId": "123456" }, "click_action": "https://example.com/fish_photos", "actions": [ { "title": "Like", "action": "like", "icon": "icons/heart.png" }, { "title": "Unsubscribe", "action": "unsubscribe", "icon": "icons/cross.png" } ] } }, "token": "<APP_INSTANCE_REGISTRATION_TOKEN>" } }Notice that you are able to set new parameters, such as actions, which gives the user different ways to interact with the notification. In the example below, users have the option to choose from actions to like the photo or to unsubscribe.
To handle action clicks in your app, you need to add an event listener in the default firebase-messaging-sw.js file (or your custom service worker). If an action button was clicked, event.action will contain the string that identifies the clicked action. Here's how to handle the "
like" and "unsubscribe" events on the client:// Retrieve an instance of Firebase Messaging so that it can handle background messages. const messaging = firebase.messaging(); // Add an event listener to handle notification clicks self.addEventListener('notificationclick', function(event) { if (event.action === 'like') { // Like button was clicked const photoId = event.notification.data.photoId; like(photoId); } else if (event.action === 'unsubscribe') { // Unsubscribe button was clicked const notificationType = event.notification.data.notificationType; unsubscribe(notificationType); } event.notification.close(); });The SDK will still handle regular notification clicks and redirect the user to your click_action link if provided. To see more on how to handle click actions on the client, check out the guide.
Since different browsers support different parameters in different platforms, it's important to check out the browser compatibility documentation to ensure your notifications work as intended.

Start making your business more accessible using Primer
Thursday, May 17, 2018
Posted by Lisa Gevelber, VP Marketing Ads and AmericasOver one billion people in the world have some form of disability.
That's why we make accessibility a core consideration when we develop new products—from concept to launch and beyond. It's good for users and good for business: Building products that don't consider a diverse range of needs could mean missing a substantial group of potential users and customers.
But impairments and disabilities are as varied as people themselves. For designers, developers, marketers or small business owners, making your products and designs more accessible might seem like a daunting task. How can you make sure you're being more inclusive? Where do you start?
Today, Global Accessibility Awareness Day, we're launching a new suite of resources to help creators, marketers, and designers answer those questions and build more inclusive products and designs.
The first step is learning about accessibility. Simply start by downloading the Google Primer app and search "accessibility." You'll find five-minute lessons that help you better understand accessibility, and learn practical tips to start making your own business, products and designs more accessible, like key design principles for building a more accessible website. You may even discover that addressing accessibility issues can improve the user experience for everyone. For instance, closed captions can make your videos accessible to more people whether they have a hearing impairment or are sitting in a crowded room.
Next, visit the Google Accessibility page and discover free tools that can help you make your site or app more accessible for more people. The Android Developers site also contains a wide range of suggestions to help you improve the accessibility of your app.
We hope these resources will help you join us in designing and building for a more inclusive future. After all, an accessible web and world is a better one—both for people and for business.
"Excited to see the new lessons on accessibility that Primer launched today. They help us learn how to start making websites and products more accessible. With over 1 billion people in the world with some form of disability, building a more inclusive web is the right thing to do both for people and for business."
