From conception, the open source Accelerated Mobile Pages Project has had a clear goal --- to make the mobile web experience better and faster for users. This extends beyond content to creating a user-first approach to advertising as well.
To realize this vision, the AMP team created an advertising solution that follows four core principles:
Ads in AMP are delivered using the amp-ad component. Using this component you can configure your ads in a number of ways such as the width, length, layout mode and ad loading strategy. Different ad networks might allow even more options.
Here is an example of an DoubleClick responsive ad implementation in AMP:
<amp-ad width="414" height="457" layout=”responsive” type="doubleclick" data-slot="/35096353/amptesting/image/flex"> </amp-ad>
The type attribute informs the amp-ad component which ad platform to use. In this case we want DoubleClick and therefore the type value is doubleclick. For above the fold responsive ad implementation please use layout="fixed-height" instead and limit the ad height so users will get a fast loading content-focused experience from the very start.
type
doubleclick
layout="fixed-height"
Any attributes starting with data- in amp-ad are ad platform-specific attributes, including the data-slot attribute in the snippet above. Each ad platform will have different attributes available to configure. For example, compare the above DoubleClick example with another AMP ad example that uses the Rubicon platform:
data-
data-slot
<amp-ad width=320 height=50 type="rubicon" data-method="smartTag" data-account="14062" data-site="70608" data-zone="335918" data-size="43"> </amp-ad>
For more amp-ad implementation examples, please check out AMP By Example. You can also check out the amp-ad documentation for the complete list of supported ad networks and their configuration semantics.
The team is also developing newer, better ways to bring the benefits of AMP to the ads ecosystem with initiatives like AMP for Ads and AMP Ad Landing Pages. These solutions will enable advertisers to design creatives and ad landing pages that are more consistent with the AMP experience publishers are bringing to users. We believe this will bring us closer to the goal of making the entire mobile web experience faster and better for everybody.

With Google Cardboard and Daydream, our Google VR team is working to bring virtual reality to everyone. In addition to making VR more accessible by using the smartphone in your pocket, we recently launched the Google VR SDK out of beta, with native integration for Unity and UE4, to help make it easier for more developers to join the fold.
To further support and encourage new developers to build VR experiences, we’ve partnered with Udacity to create the VR Developer Nanodegree. Students will learn how to create 3D environments, define behaviors, and make VR experiences comfortable, immersive, and performant.
Even with more than 50 million installs of Google Cardboard apps on Google Play, these are still the early days of VR. Students who complete the VR Developer Nanodegree learn by doing, and will graduate having completed a portfolio of VR experiences.

Window shopping and showrooms let us imagine what that couch might look like in our living room or if that stool is the right height, but Tango can help take out the guesswork using augmented reality. Place virtual furniture in your real room, walk around, and try different colors.
Tango-enabled apps like WayfairView make it easy to visualize and rearrange new furniture in your home. We sat down with the Wayfair team to learn more about their app and see how Tango helps power new AR shopping experiences:
Google: Please tell us about your Tango app.
Mike: Wayfair offers a massive selection of products online. We believe that the ability for customers to visualize products in their living space augments our online experience, and solves real customer problems such as: Will this product fit in my space? and Will this match the rest of my environment?
Why are you excited for your customers to start using WayfairView?
One of the biggest barriers that online shopping poses is the inability for a customer to get a good sense of how a product would fit in their room, and what it would look like in their living space. With WayfairView, we aim to help our customers better visualize our products - going above and beyond a flat, 2D image and providing them with an accurate 3D rendering of what the full-size item could look like in their home. Not only is this a great extension of the customer experience, it’s also a practical approach to figure out how the product fits into the user’s space before ordering it.
How did you get started developing for Tango?
I signed up to buy a dev kit in 2014 because he was personally interested in scanning 3D objects and environments. I ended up using it for a hackathon to build the first prototype of what is now WayfairView. One of my teammates, Shrenik Sadalgi, has always been interested in AR technology and had participated in Tango hackathons in years prior. He thought this particular flavor of AR, i.e Markerless in the form factor of a mobile device, had the potential of providing a seamless, easy user experience for Wayfair customers.
Was there something unique to the Tango platform that made it particularly appealing?
AR technology has been around for a while, but Tango is making it accessible by providing the technology in a way that is user friendly. Specifically, the Tango platform excels in accurate tracking, which allowed Wayfair’s R&D team to focus on building a great experience for our customers. No markers, no HMDs, no cords that can get tangled, but still powerful.
What were some of the challenges you faced building for Tango?
The biggest challenge Wayfair faces with AR technology is more about the experience than the device, which is in big part thanks to Tango. Our goal was to introduce an entirely new way of shopping for furniture in a way that is user friendly. Not having to worry about the inner workings of Tango helped us focus on making the furniture look as real as possible, scaling the app with our massive catalog, and getting to market in a short period of time.
What surprised you during the Tango development process?
The learning curve for Tango was minimal. We were able to get started very quickly using example code. It was pretty remarkable how the stability of the platform (primarily the tracking) kept improving over the period of time that we worked on the app.
Which platform did you build your Tango app on, and why?
We wrote the core of the app using Unity in C# - we wanted all the 2D UI to be in native Android to match the Wayfair native Android experience. This also gave us the opportunity to re-use code from the existing Wayfair Android app. We saw significant performance improvements by using native Android to create the 2D UI as well, which also makes the UI easier to update when the next UI theme of Android comes along.
What features can customers look forward to in a future WayfairView update?
We would love to add the ability to search for products by space: imagine drawing a cube in your real space and finding all products that fit the space. We also want to allow users to stack virtual products on top of each other to help them visualize how a virtual table lamp would look on top of a virtual table. Of course, we also want to make the products look even more real and add more products that can be visualized on WayfairView.
How do you think that this will change the way people shop for household goods?
WayfairView makes it easier than ever for customers to visualize online goods in their home at full scale, giving them an extra level of confidence when making an online purchase. We believe Tango has the potential to become a ubiquitous technology, just like smartphone cameras and mobile GPS. Ultimately, we anticipate that this will further accelerate the shift from brick and mortar to online.
We also imagine that WayfairView will be a very useful tool for our designers as they share their design proposal and vision with their customers.

In the digital world, whether you’re writing stories for your loyal readers, creating creative content that your fans love, helping the digital community, or providing items and services for your customer, understanding your audience is at the heart of it all. Key to unlocking that information is access to tools for measuring your audience and understanding their behavior. In addition to making your page load faster, Accelerated Mobile Pages (AMP) provides multiple analytics options without compromising on performance.
You can choose to use a solution like amp-pixel that behaves like a simple tracking pixel. It uses a single URL that allows variable substitutions, so it’s very customizable. See the amp-pixel documentation for more detail.
The amp-analytics component, on the other hand, is a powerful solution that recognizes many types of event triggers to help you collect specific metrics. Since amp-analytics is supported by multiple analytics providers, this means you can use amp-analytics to configure multiple endpoints and data sets. AMP then manages all of the instrumentation to come up with the data specified and shares it with these analytics solution providers.
To use amp-analytics, include the component library in your document's <head>:
<head>
<script async custom-element="amp-analytics" src="https://cdn.ampproject.org/v0/amp-analytics-0.1.js"></script>
And then include the component as follows (for these examples, make sure to specify your own account number instead of the placeholder):
<amp-analytics type="googleanalytics"> <script type="application/json"> { "vars": { "account": "UA-YYYY-Y" }, "triggers": { "defaultPageview": { "on": "visible", "request": "pageview", "vars": { "title": "Name of the Article" } } } } </script> </amp-analytics>
The JSON format is super flexible for describing several different types of events and it does not include any JavaScript code which could potentially lead to mistakes.
Expanding the above example, we can add another trigger, clickOnHeader:
clickOnHeader
<amp-analytics type="googleanalytics"> <script type="application/json"> { "vars": { "account": "UA-YYYY-Y" }, "triggers": { "defaultPageview": { "on": "visible", "request": "pageview", "vars": { "title": "Name of the Article" } }, "clickOnHeader": { "on": "click", "selector": "#header", "request": "event", "vars": { "eventCategory": "examples", "eventAction": "clicked-header" } } } } </script> </amp-analytics>
For a detailed description of data sets you can request, as well as the complete list of analytics providers supporting amp-analytics, check out the amp-analytics documentation. You can also see more implementation examples in the Amp By Example site.
If you want to conduct a user experience experiment on your AMP pages, such as an A/B test, you can use the amp-experiment element. Any configurations done in this element will also be exposed to amp-analytics and amp-pixel, so you can easily do a statistical analysis of your experiment.
There are still plenty of ongoing developments for AMP analytics to help you gain insights as you AMPlify the user experience on your site. Visit the AMP Project roadmap to see a summary of what the team is cooking up. If you see some features missing, please file a request on GitHub.
At Google I/O, we announced Daydream—Google's platform for high quality, mobile virtual reality—and released early developer resources to get the community started with building for Daydream. Since then, the team has been hard at work, listening to feedback and evolving these resources into a suite of powerful developer tools.
Today, we are proud to announce that the Google VR SDK 1.0 with support for Daydream has graduated out of beta, and is now available on the Daydream developer site. Our updated SDK simplifies common VR development tasks so you can focus on building immersive, interactive mobile VR applications for Daydream-ready phones and headsets, and supports integrated asynchronous reprojection, high fidelity spatialized audio, and interactions using the Daydream controller.
To make it even easier to start developing with the Google VR SDK 1.0, we’ve partnered with Unity and Unreal so you can use the game engines and tools you’re already familiar with. We’ve also updated the site with full documentation, reference sample apps, and tutorials.
Native Unity integration
This release marks the debut of native Daydream integration in Unity, which enables Daydream developers to take full advantage of all of Unity’s optimizations in VR rendering. It also adds support for features like head tracking, deep linking, and easy Android manifest configuration. Many Daydream launch apps are already working with the newest integration features, and you can now download the new Unity binary here and the Daydream plugin here.
Native UE4 integration
We’ve made significant improvements to our UE4 native integration that will help developers build better production-quality Daydream apps. The latest version introduces Daydream controller support in the editor, a neck model, new rendering optimizations, and much more. UE4 developers can download the source here.
Get started today
While the first Daydream-ready phones and headset are coming this fall, you can start developing high-quality Daydream apps right now with the Google VR SDK 1.0 and the DIY developer kit.
We’re also opening applications to our Daydream Access Program (DAP) so we can work closely with even more developers building great content for Daydream. Submit your Daydream app proposal to apply to be part of our DAP.
When you create content for the Daydream platform, you know your apps will work seamlessly across every Daydream-ready phone and headset. Daydream is just getting started, and we’re looking forward to working together to help you build new immersive, interactive VR experiences. Stay tuned for more information about Daydream-ready phones and the Daydream headset and controller coming soon.

Last week, we clarified the expectations and responsibilities when accessing Google user data via OAuth 2.0. Today, we’re announcing that in order to better protect users, we are increasing account security for enterprise Gmail users effective October 5, 2016. At this time, a new policy will take effect whereby users in a Google Apps domain, while changing their passwords on or after this date, will result in the revocation of the OAuth 2.0 tokens of apps that access their mailboxes using Gmail-based authorization scopes. Please note that users will not notice any specific changes on this date and their applications will continue to work. It is only when a user changes their password from that point moving forward that their Gmail-related tokens become invalid.
Developers should modify their applications to handle HTTP 400 or 401 error codes resulting from revoked tokens and prompt their users to go through the OAuth flow again to re-authorize those apps, such that they can access the user’s mailbox again (additional details below). Late last year, we announced a similar, planned change to our security policy that impacted a broader set of authorization scopes. We later decided not to move forward with that change for Apps customers and began working on a less impactful update as described above.
What is a revoked token?
A revoked OAuth 2.0 token no longer provides access to a user’s resources. Any attempt to use a revoked token in API calls will result in an error. Any existing token strings will no longer have any value and should be discarded. Applications accessing Google APIs should be modified to handle failed API calls.
Token revocation itself is not a new feature. Users have always been able to revoke access to applications in Security Checkup, and Google Apps admins have the ability to do the same in the Admin console. In addition, tokens that were not used for extended periods of time have always been subject to expiration or revocation. This change in our security policy will likely increase the rate of revoked tokens that applications see, since in some cases the process will now take place automatically.
What APIs and scopes are impacted?
To achieve the security benefits of this policy change with minimal admin confusion and end-user disruption, we’ve decided to limit its application to mail scopes only and to exclude Apps Script tokens. Apps installed via the Google Apps Marketplace are also not subject to the token revocation. Once this change is in effect, third-party mail apps like Apple Mail and Thunderbird―as well as other applications that use multiple scopes that include at least one mail scope―will stop accessing data upon password reset until a new OAuth 2.0 token has been granted. Your application will need to detect this scenario, notify the user that your application has lost access to their account data, and prompt them to go through the OAuth 2.0 flow again.
Mobile mail applications are also included in this policy change. For example, users who use the native mail application on iOS will have to re-authorize with their Google account credentials when their password has been changed. This new behavior for third-party mail apps on mobile aligns with the current behavior of the Gmail apps on iOS and Android, which also require re-authorization upon password reset.
How can I determine if my token was revoked?
Both short-lived access tokens and long-lived refresh tokens will be revoked when a user changes their password. Using a revoked access token to access an API or to generate a new access token will result in either HTTP 400 or 401 errors. If your application uses a library to access the API or handle the OAuth flow, then these errors will likely be thrown as exceptions. Consult the library’s documentation for information on how to catch these exceptions. NOTE: because HTTP 400 errors may be caused by a variety of reasons, expect the payload from a 400 due to a revoked token to be similar to the following:
{ "error_description": "Token has been revoked.", "error": "invalid_grant" }
How should my application handle revoked tokens?
This change emphasizes that token revocation should be considered a normal condition, not an error scenario. Your application should expect and detect the condition, and your UI should be optimized for restoring tokens.
To ensure that your application works correctly, we recommend doing the following:
If your application uses incremental authorization to accrue multiple scopes in the same token, you should track which features and scopes a given user has enabled. The end result is that if your app requested and obtained authorization for multiple scopes, and at least one of them is a mail scope, that token will be revoked, meaning you will need to prompt your user to re-authorize for all scopes originally granted.
Many applications use tokens to perform background or server-to-server API calls. Users expect this background activity to continue reliably. Since this policy change also affects those apps, this makes prompt notification requesting re-authorization even more important.
What is the timeline for this change?
To summarize, properly configured applications should be expected to handle invalid tokens in general, whether they be from expiration, non-existence, and revocation as normal conditions. We encourage developers to make any necessary changes to give their users the best experience possible. The policy change is planned to take effect on October 5, 2016.
Please see this Help Center article and FAQ for more details and the full list of mail scopes. Moving forward, any additional scopes to be added to the policy will be communicated in advance. We will provide those details as they become available.
