The latest Android App Bundle updates including the additional languages API

Posted by Wojtek Kaliciński, Developer Advocate, Android

Last year, we launched Android App Bundles and Google Play's Dynamic Delivery to introduce modular development, reduce app size and streamline the release process. Since then, we've seen developers quickly adopt this new app model in over 60,000 production apps. We've been excited to see developers experience significant app size savings and reductions in the time needed to manage each release, and have documented these benefits in case studies with Duolingo and redBus.

Thank you to everyone who took the time to give us feedback on our initial launch. We're always open to new ideas, and today, we're happy to announce some new improvements based on your suggestions:

  • A new additional languages install API, which supports in-app language pickers
  • A streamlined publishing process for instant-enabled app bundles
  • A new enrollment option for app signing by Google Play
  • The ability to permanently uninstall dynamic feature modules that are included in your app's initial install


Additional languages API

When you adopt the Android App Bundle as the publishing format for your app, Google Play is able to optimize the installation by delivering only the language resources that match the device's system locales. If a user changes the system locale after the app is installed, Play automatically downloads the required resources.

Some developers choose to decouple the app's display language from the system locale by adding an in-app language switcher. With the latest release of the Play Core library (version 1.4.0), we're introducing a new additional languages API that makes it possible to build in-app language pickers while retaining the full benefits of smaller installs provided by using app bundles.

With the additional languages API, apps can now request the Play Store to install resources for a new language configuration on demand and immediately start using it.

Get a list of installed languages

The app can get a list of languages that are already installed using the SplitInstallManager#getInstalledLanguages() method. 

val splitInstallManager = SplitInstallManagerFactory.create(context)
val langs: Set<String> = splitInstallManager.installedLanguages

Requesting additional languages

Requesting an additional language is similar to requesting an on demand module. You can do this by specifying a language in the request through SplitInstallRequest.Builder#addLanguage(java.util.Locale). 

val installRequestBuilder = SplitInstallRequest.newBuilder()
installRequestBuilder.addLanguage(Locale.forLanguageTag("pl"))
splitInstallManager.startInstall(installRequestBuilder.build())

The app can also monitor install success with callbacks and monitor the download state with a listener, just like when requesting an on demand module.

Remember to handle the SplitInstallSessionStatus.REQUIRES_USER_CONFIRMATION state. Please note that there was an API change in a recent Play Core release, which means you should use the new SplitInstallManager#startConfirmationDialogForResult() together with Activity#onActivityResult(). The previous method of using SplitInstallSessionState#resolutionIntent() with startIntentSender() has been deprecated.

Check out the updated Play Core Library documentation for more information on how to access the newly installed language resources in your activity.

We've also updated our dynamic features sample on GitHub with the additional languages API, including how to store the user's language preference and apply it to your activities at startup.

Please note that while the additional languages API is now available to all developers, on demand modules are in a closed beta for the time being. You can experiment with on demand modules in your internal, open, and closed test tracks, while we work with our partners to make sure this feature is ready for production apps.

Instant-enabled App Bundle

In Android Studio 3.3, we introduced a way to build app bundles that contain both the regular, installed version of your app as well as a Google Play Instant experience for modules marked with the dist:instant="true" attribute in their AndroidManifest.xml: 

<manifest ... xmlns:dist="http://schemas.android.com/apk/distribution">
    <dist:module dist:instant="true" />
    ...
</manifest>

Even though you could use a single project to generate the installed and instant versions of your app, up until now, developers were still required to use product flavors in order to build two separate app bundles and upload both to Play.

We're happy to announce that we have now removed this restriction. It's now possible to upload a single, unified app bundle artifact, containing modules enabled for the instant experience. This functionality is now available for everyone.

After you build an instant-enabled app bundle, upload it to any track on the Play Console, and you'll be able to select it when creating a new instant app release. This also means that the installed and instant versions of your app no longer need different version codes, which will simplify the release workflow.

Opt in to app signing by Google Play

You need to enable app signing by Google Play to publish your app using an Android App Bundle and automatically benefit from Dynamic Delivery optimizations. It is also a more secure way to manage your signing key, which we recommend to everyone, even if you want to keep publishing regular APKs for now.

Based on your feedback, we've revamped the sign-up flow for new apps to make it easier to initialize the key you want to use for signing your app.

Now developers can explicitly choose to upload their existing key without needing to upload a self-signed artifact first. You can also choose to start with a key generated by Google Play, so that the key used to locally sign your app bundle can become your upload key.

Read more about the new flow.

Permanent uninstallation of install time modules

We have now added the ability to permanently uninstall dynamic feature modules that are included in your app's initial install.

This is a behavior change, which means you can now call the existing SplitInstallManager#deferredUninstall() API on modules that set onDemand="false". The module will be permanently uninstalled, even when the app is updated.

This opens up new possibilities for developers to further reduce the installed app size. For example, you can now uninstall a heavy sign-up module or any other onboarding content once the user completes it. If the user navigates to a section of your app that has been uninstalled, you can reinstall it using the standard on demand modules install API.

We hope you enjoy these improvements and test them out in your apps. Continue to share your feedback as we work to make these features even more useful for you!

Why you should localize your app or game for Middle East and North Africa

By Mohammad El-Saadi, Business Development, Google Play

The Middle East and North Africa (MENA) region is a fast growing market for app and game developers on Google Play, and localizing is crucial to making the most of the opportunity. For example, the main grossing apps & games in Saudi Arabia have localized their store listings and their actual app and game on Google Play.

The British team behind the Skyscanner travel app had already localised it into more than 15 languages, yet the launch in Arabic was a huge milestone for them. Arabic speaking users really appreciated the localization and the app's average user rating increased from 4.62☆ to 4.77☆ after localization. Users engaged with the app longer, with an increase of 30% in their average session duration. Additionally 50% more travellers have been redirected to Skyscanner partners to book flight, hotel and car hire deals.


Skyscanner opening screen in English and in Arabic
But how difficult is it to correctly localize your app or game to Arabic?

The team at Skyscanner managed to develop Right-To-Left (RTL) Arabic language support within the app in two weeks: "Our initial fear was that we would need lots of manual coding for the layouts. However, the Android layout system handled all of the cases really well. We were already using *Start and *End margin and padding in line with guidelines, but there's also Android Studio support and Lint check to fix any issues automatically." says Tamas Chrenoczy-Nagy, Senior Software Engineer.

Many other top apps and games developers are successfully investing in localizing for MENA users. For example, when game developer Pocket Gems localised War Dragons, the installs by Arabic speaking users tripled. Their percentage of revenue from Arabic language players also went from effectively 0% to ~1.5%.

We just refreshed the Now in Arabic collection (MENA only) with 16 newly localized apps and games, including titles like Netflix, Periscope and Clash of Queen Dragons. It will be live until May 11 on Google Play in the following countries: Algeria, Bahrain, Egypt, Jordan, Kuwait, Lebanon, Morocco, Oman, Qatar, Saudi Arabia, Tunisia and United Arab Emirates.


Check our Localization Checklist for best practices when localizing for any language, and our Going Global Playbook. When your app or game in Arabic is ready, you can self-nominate to be part of future refreshes of the Now in Arabic collection by filling in this form.

3 Exercises To Get Your Fitness App In Shape

By: Mary Liz McCurdy, Health & Fitness Lead, Google Play

(Originally published on Android Central)

It's an exciting time to be a health & fitness app developer. With people shelling out on fitness more than ever before, we're seeing record high levels of gym memberships and attendance, the rise of boutique fitness, and an emphasis on connected devices.

Paramount to this growth is the integration of smart technology. Whether it be through streaming video, wearables, or mobile apps, technology empowers us with instant access to high quality workouts, sensor biofeedback, and endless on-demand inspiration. At Google Play, we've seen this growth reflected by the incredible popularity of health & fitness apps. In fact, this is one of Google Play's fastest growing app categories, boasting the most engaged 30d active users.

As the resident health & fitness expert on Google Play, I had the opportunity to speak about what's driving the category's growth at the recent Wearables Technology Show. Here are the top three recommendations I shared with the audience to help coach developers towards building more valuable app experiences:

Lose it!

#1: Be invisible

We all know how painful manually logging activity and biometrics is- be it calorie tracking, workouts, moods, or hormone cycles. Manual logging is actually the number one reason users drop off.

What you should do: Minimize distraction with automation wherever possible while maximizing value at the appropriate moments. Remember that you are in all likelihood a companion experience to the main event.

Lose It! makes food tracking easier by using your phone's camera and image recognition technology to identify foods and their nutritional information. Goodbye manual calorie counting!

Strava uses auto pause detection, recognizing when you are resting during exercise so you don't need to fiddle with your device and can stay safe and in the zone.

Freeletics

#2: Be personal

Investing in robust personalization has been the driving factor in improving app engagement and buyer conversion among many of our top developers.

What you should do: Personalize the experience for each user or distinct user cohorts by leveraging technology like the Awareness API, Fit API, Google Sign In, and Facebook Login to intelligently pull in relevant user data. Think about your first-time users, power users, high value users, etc. and treat them uniquely.

Freeletics personalizes onboarding and the overall app experience based on gender and fitness level leading to a 58% increase in weekly active sessions.

Workout Trainer by Skimble increased user engagement by 30% through personalizing training programs based on user fitness assessments, goals, and workout patterns.

Glow

#3: Be assistive

The rise of smartphones, wearables and IoT have left us swimming in data and dashboards and left many consumers wondering, so what?

What you should do: Offer insights and suggestions, not just raw data. Users are not engineers and generally do not want to process complex data or dashboards. In most cases, they want you to tell them what to do in the moment or provide digestible summaries after the fact. Keep it simple.

Glow provides personalized insights that leverage user-inputted data and third party data from Google Fit to help couples achieve their fertility goals.

Beddit gives personalized daily tips to improve your sleep and wellness by analyzing sleep cycles, resting heart rate, respiration, room temperature, and more.

At the end of the day, changing health and fitness habits is hard. Make it easier for your users by seamlessly guiding them on what they personally need to do to achieve their goal. It's that simple ;) We encourage you to experiment with these exercises to get your app fit for the millions of Android users looking to live a healthier, happier life.

Taking the final wrapper off of Android 7.0 Nougat

Posted by Dave Burke, VP of Engineering
Android Nougat

Android 7.0 Nougat

Today, Android 7.0 Nougat will begin rolling out to users, starting with Nexus devices. At the same time, we’re pushing the Android 7.0 source code to the Android Open Source Project (AOSP), extending public availability of this new version of Android to the broader ecosystem.

We’ve been working together with you over the past several months to get your feedback on this release, and also to make sure your apps are ready for the users who will run them on Nougat devices.

What’s inside Nougat

Android Nougat reflects input from thousands of fans and developers like you, all around the world. There are over 250 major features in Android Nougat, including VR Mode in Android. We’ve worked at all levels of the Android stack in Nougat — from how the operating system reads sensor data to how it sends pixels to the display — to make it especially built to provide high quality mobile VR experiences.

Plus, Nougat brings a number of new features to help make Android more powerful, more productive and more secure. It introduces a brand new JIT/AOT compiler to improve software performance, make app installs faster, and take up less storage. It also adds platform support for Vulkan, a low-overhead, cross-platform API for high-performance, 3D graphics. Multi-Window support lets users run two apps at the same time, and Direct Reply so users can reply directly to notifications without having to open the app. As always, Android is built with powerful layers of security and encryption to keep your private data private, so Nougat brings new features like File-based encryption, seamless updates, and Direct Boot.

You can find all of the Nougat developer resources here, including details on behavior changes and new features you can use in your apps. An overview of what's new for developers is available here, and you can explore all of the new user features in Nougat here.

Multi-window mode in Android Nougat

The next wave of users

Starting today and rolling out over the next several weeks, the Nexus 6, Nexus 5X, Nexus 6P, Nexus 9, Nexus Player, Pixel C, and General Mobile 4G (Android One) will get an over-the-air software update to Android 7.0 Nougat. Devices enrolled in the Android Beta Program will also receive this final version.

And there are many tasty devices coming from our partners running Android Nougat, including the upcoming LG V20, which will be the first new smartphone that ships with Android Nougat, right out of the box.

With all of these new devices beginning to run Nougat, now is the time to publish your app updates to Google Play. We recommend compiling against, and ideally targeting, API 24. If you’re still testing some last minute changes, a great strategy to do this is using Google Play’s beta testing feature to get early feedback from a small group of users — including those using Android 7.0 Nougat — and then doing a staged rollout as you release the updated app to all users.

What’s next for Nougat?

We’re moving Nougat into a new regular maintenance schedule over the coming quarters. In fact, we’ve already started work on the first Nougat maintenance release, that will bring continued refinements and polish, and we’re planning to bring that to you this fall as a developer preview. Stay tuned!

We’ll be closing open bugs logged against Developer Preview builds soon, but please keep the feedback coming! If you still see an issue that you filed in the preview tracker, just file a new issue against Android 7.0 in the AOSP issue tracker.

Thanks for being part of the preview, which we shared earlier this year with an eye towards giving everyone the opportunity to make the next release of Android stronger. Your continued feedback has been extremely beneficial in shaping this final release, not just for users, but for the entire Android ecosystem.

Introducing new Android training programs with Udacity

Posted by Peter Lubbers, Senior Program Manager, Google Developer Training

We know how important it is for you to efficiently develop the skills to build better Android apps and be successful in your jobs. To meet your training needs, we’ve partnered with Udacity to create Android training courses, ranging from beginner to more advanced content.

Last week at Google I/O we announced the Android Nanodegree, an education credential that is designed for busy people to learn new skills and advance their careers in a short amount of time from anywhere at any time. The nanodegree ties together our Android courses, and provides you with a certificate that may help you be a more marketable Android developer.

Training courses

All training courses are developed and taught by expert Google instructors from the Developer Platform team. In addition to updating our popular Developing Android Apps course and releasing Advanced Android App Development, we now have courses for everyone from beginning programmers to advanced developers who want to configure their Gradle build settings. And then there's all the fun stuff in between—designing great-looking, high performance apps, making your apps run on watches, TVs, and in cars, and using Google services like Maps, Ads, Analytics, and Fit.

Each course is available individually, without charge, at udacity.com/google. Our instructors are waiting for you:

Android Nanodegree

You can also enroll in the new Android Nanodegree for a monthly subscription fee, which gives you access to coaches who will review your code, provide guidance on your project, answer questions about the class, and help keep you on track when you need it.

More importantly, you will learn by doing, focusing only on where you need to grow. Since the Nanodegree is based on your skills and the projects in your portfolio, you do not need to complete the courses that address the skills you already have. You can focus on writing the code and building the projects that meet the requirements for the Nanodegree credential. We’ll also be inviting 50 Android Nanodegree graduates to Google's headquarters in Mountain View, California, for a three day intensive Android Career Summit in November. Participants will have the opportunity to experience Google’s company culture and attend workshops focused on developing their personal career paths. Participants will then leverage the skills learned from Udacity’s Android Nanodegree during a two-day hackathon.

To help you learn more about this program and and courses within it, Google and Udacity are partnering up for an "Ask the Experts" live streamed series. In the first episode on Wednesday, June 3rd at 2pm PDT, Join Sebastian Thrun, Peter Lubbers and Jocelyn Becker who will be answering your questions on the Nanodegree. RSVP here and ask and vote for questions here.

Android training in Arabic

We also believe that everyone has the right to learn how to develop Android apps. Today, there is a great need for developers in countries outside of the United States as software powers every industry from food and transportation to healthcare and retail. As a first step in getting the Android Nanodegree localized and targeted for individual countries, we have worked with the Government of Egypt and Udacity to create end-to-end translations of our top Android courses into Arabic (including fully dubbed video). Google will offer 2,000 scholarships to students to get a certificate for completing the Arabic version of the Android Fundamentals course. Google will also host job fairs and sessions for students with local employers and the Egyptian Government. For more information, see www.udacity.com/egypt.

Empowering successful global businesses on Google Play

Posted by Ellie Powers, Product Manager, Google Play

With more than 50 billion app installs over the past year from users across 190 countries, Google Play continues to see incredible growth thanks to developers like you creating amazing experiences. Play is now reaching more than one billion users every month.

In February, we announced that we had paid out more than $7 billion to developers in the prior year alone. This week at Google I/O, we’re introducing new and powerful tools to help you further grow your business, improve decision making based on smarter insights, and better engage your user base with more relevant content.

Acquire users from the Developer Console

Once you’ve built a great app, the next important step is to proactively find ways to promote it and grow a loyal user base. App install ads are one powerful way to do that. In the coming months, you’ll be able to quickly and easily set up ad campaigns right from within the Google Play Developer Console for the first time.

All you need to do is set a total budget and the cost you're willing to pay per user and we’ll scale your app promotion across our networks, including Google Search, AdMob, YouTube and the search ads we’re piloting on Google Play. With this new feature, you will will be able to better find the customers that are most likely to install your app.

Actionable insights with the Acquisition and Conversion Funnel

Whether you pay to acquire users or not, you want to know where they’re coming from. Through the Developer Console, you will soon be able to get a snapshot of how many users visit your Store listing, install your app, and make purchases. You’ll see where your most valuable users come from — across organic and paid traffic — and better understand where to focus your efforts.

Optimize your Play store listing with experiments

Your Play Store listing is extremely important, as it’s often the first touch point users have with your app. Starting today, we’re making it easier to optimize this page with support for A/B tests. You can run experiments with different versions of text and graphics to see which are most effective in converting visits into installs on Google Play. In our pilot program, we were thrilled to see that some developers like Kongregate achieved double-digit improvements in their install rates so far.

Test your app automatically on real devices with Cloud Test Lab

With the large variety of Android form factors in the market, testing your app on real devices is a critical step to ensuring a positive user experience on any device. However, you may not have access to every device that your users do. So we’re integrating the newly announced Cloud Test Lab into the Developer Console, which will allow you to automatically test your apps on hundreds of popular physical Android devices for free. We’re going to be rolling out this pilot program gradually, so we’ll welcome your feedback on it.

For each APK you upload to an alpha or beta channel, Google Play will execute fully automated testing of your app against physical devices matching your app targeting criteria and output a report with a detailed analysis of issues, including screenshots and logs. Google Cloud Test Lab will roll out to all developers later this year; you can sign-up to become a tester in the Developer Console now.

Build a data-driven games business with Player Analytics

Google Play Games has activated more than 180M new users in the past six months and continues to be the fastest growing mobile gaming platform in history.

Over the coming months, we're adding new reports, player segments, game metrics, and event types to Player Analytics to help you manage your games business. We're also bringing enhancements to our live operations tools that will enable dynamic content updates that make games feel more alive and engaging, gameplay to respond to changing player needs, and more fun, personalized user experiences. As the bar for success in mobile gaming continues to rise, we’re continuing to evolve our tools to help you meet the soaring expectations of players.

Find great apps – developer pages and search results

There are several ways in which we are improving the discoverability of great apps and games on Google Play to help drive more engagement. Starting today, you can create a unique homepage on Google Play to promote your entire app catalog. With your own developer page, you are able to upload graphics, explain what your company is all about and pick a special app to feature. This gives you a single destination to promote all of your apps on Google Play.

We are also helping guide users with broad interests (e.g. “shopping”) in a new search results experience.

The focus is on organizing results in an intuitive way that allows users to narrow their intent -- such as grouping shopping apps into coupons apps and fashion apps. By doing so, users will be able to better see the range of apps that satisfy their needs, while also increasing the chances of discovering new and innovative apps that you’re building.

Family-friendly content in Google Play

Starting today, we’re making it easier to find family-friendly content on Google Play through new discovery features. On the Apps & Games and Movies & TV homepages, users can now hit the “Family” star to see a curated set of options for specific age groups. In Play Books, tap the “Children’s Books” star. These pages let you browse by age ranges to find content that’s the best fit for the family. If you’ve already opted-in your apps to the Designed for Families program and they’ve met the requirements, they’ll be included in the new family section so that parents can find suitable, trusted, high-quality apps and games more easily. Find out more about opting-in to the Designed for Families program.

Join us at Google I/O 2015

To learn more, tune-in live to “Developers connecting the world through Google Play” at 1pm PT / 4pm ET / 9pm GMT on May 29 on google.com/io.

If you’re at I/O 2015, come along to our breakout sessions where we’ll be talking about and demo’ing these new features. Find our sessions in the I/O 2015 schedule.
