Hamilton and Posse, a design and development agency in New York, had three short months to develop and launch mobile apps for the hit Broadway show. How did they accomplish that? Using Flutter, Google's new mobile UI framework.
Reaching millions of users — with an outstanding half a million monthly active users and featured on both the App Store and Google Play— the apps let fans enter the ticket lottery, buy merchandise, play trivia, take selfies with a #HamCam, read frequently updated news and interviews, and more.
Watch this video case study to see how Flutter continues to help apps like Hamilton succeed on iOS and Android. You can read more details about the development of this app on Posse's blog post.

At Google I/O, we announced our ongoing investment in Blockly with the release of a native Android version. We also highlighted significant improvements to the performance of web Blockly, which enables better rendering performance on mobile devices. Now iOS developers will have access to an open-source developer preview of Blockly for iOS that supports building better experiences on mobile, including multi-touch and enhanced animations as new experimental features.
Today’s release supports our ongoing efforts to enable developers to create consistent, high-quality, beginner programming experiences - as block-based programming interfaces can make coding more accessible by removing syntax errors and supporting “tinkerability.” We believe that coding is more than just a set of technical skills; coding is a valuable tool for everyone, empowering users from around the globe to imagine, invent, and explore.
With Blockly for iOS, developers can add Blockly views and fragments directly into their iOS app. This will offer tighter integration and improved performance compared to using a WebView. In this developer preview, blocks are currently optimized for tablets, but ready to customize for any app.
In addition, if you already use Blockly we're releasing a major update to the tools for creating custom blocks and configuring Blockly for your app, check out the new Blockly Developer Tools. The new tools allow you to edit and maintain a library of custom blocks, quickly configure toolboxes, and export and import files to local storage.
Click here to learn more, and get started on Blockly for iOS today. And to share feedback and get news, we welcome you to join the Blockly mailing list. We look forward to seeing your future builds!

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.

When we started building TensorFlow, supporting mobile devices was a top priority. We were already supporting many of Google’s mobile apps like Translate, Maps, and the Google app, which use neural networks running on devices. We knew that we had to make mobile a first-class part of open source TensorFlow.
TensorFlow has been available to developers on Android since launch, and today we're happy to add iOS in v0.9 of TensorFlow, along with Raspberry Pi support and new compilation options.
To build TensorFlow on iOS we’ve created a set of scripts, including a makefile, to drive the cross-compilation process. The makefile can also help you build TensorFlow without using Bazel, which is not always available.
All this is in the latest TensorFlow distribution. You can read more by visiting our Mobile TensorFlow guide and the documentation in our iOS samples and Android sample. The mobile samples allow you to classify images using the ImageNet Inception v1 classifier.
These mobile samples are just the beginning---we'd love your help and your contributions. Tag social media posts with #tensorflow so we can hear about your projects!

If you’re looking to drive usage and grow a mobile app, you’re probably testing out referrals, recommendations, and the user onboarding experience. These product flows are resource-intensive to design, build, and optimize. What if you could use a set of tools that help your users share your app, and get more of the right people to download and use your app? What if you could craft a more personalized onboarding experience in your new user’s journey?
Now in beta, App Invites let mobile app developers increase their reach, deep link new users to custom experiences, and tap into your users’ device and Google-wide contacts as a source to drive referrals. This is available for both iOS and Android app developers. We’re launching with UrbanSitter, Yummly, The CW, Coinbase and Picsart apps.
Here’s what some of our early partners had to say:
App Invites is available on both Android and iOS. Here’s what’s in the beta toolkit:

Today, we’re announcing that CocoaPods will be the primary channel to acquire Google SDKs for iOS. CocoaPods is a popular, free dependency manager for iOS that significantly simplifies the process of importing libraries and frameworks into Xcode. And it will help you manage your dependencies between our various libraries.
While there was a small but growing number of official Google Pods, as well as a few Pods written by other iOS developers, it was often difficult for developer to find the right SDK. With today’s announcement, some of our key libraries, like Google Cloud Messaging and the Google Maps SDK for iOS can now be found on the public CocoaPods service. Going forward, new iOS SDKs will be packaged and documented as Pods and published on cocoapods.org. You can find the full list of Google Pods and all supporting documentation at developer.google.com/ios/cocoapods.
If you haven't used CocoaPods yet, now is a great time to give it a try. Add GoogleAnalytics to a Podfile to start counting new users. Or pod install your way to adding AdMob ads in your app. And check out pod try, a CocoaPods plugin that allows you to quickly launch our demo projects.

Starting now, goo.gl short links function as a single link you can use to all your content — whether that content is in your Android app, iOS app, or website. Once you’ve taken the necessary steps to set up App Indexing for Android and iOS, goo.gl URLs will send users straight to the right page in your app if they have it installed, and everyone else to your website. This will provide additional opportunities for your app users to re-engage with your app.
This feature works for both new short URLs and retroactively, so any existing goo.gl short links to your content will now also direct users to your app.
Zillow shares a short URL on Twitter that automatically links to their native app.
You can also make full use of this feature by integrating the URL Shortener API into your app’s share flow, so users can share links that automatically redirect to your native app cross-platform. This will also allow others to embed links in their websites and apps which deep link directly to your app.
Take Google Maps as an example. With the new cross-platform goo.gl links, the Maps share button generates one link that provides the best possible sharing experience for everyone. When opened, the link auto-detects the user’s platform and if they have Maps installed. If the user has the app installed, the short link opens the content directly in the Android or iOS Maps app. If the user doesn’t have the app installed or is on desktop, the short link opens the page on the Maps website.
Try it out for yourself! Don’t forget to use a phone with the Google Maps app installed: http://goo.gl/maps/xlWFj.
To set up app deep linking on goo.gl:
We hope you enjoy this new functionality and happy cross-platform sharing!
