Keeping the Play Store trusted: fighting fraud and spam installs


Posted by Kazushi Nagayama, Search Quality Analyst, and Andrew Ahn, Product
Manager



We strive to continuously make Google Play the best platform for enjoying and
discovering the most innovative and trusted apps. Today we are announcing
additional enhancements to protect the integrity of the store.



Our teams work every day to improve the quality of our discovery systems. These
content discovery systems ensure that users can find and download apps they will
love. From time to time, we observe instances of developers attempting to
manipulate the placement of their apps through illegitimate means like
fraudulent installs, fake reviews, and incentivized ratings. These attempts not
only violate the href="https://play.google.com/about/developer-content-policy/?utm_campaign=android_discussion_playstore_103116&utm_source=anddev&utm_medium=blog">Google Play
Developer Policy, but also harm our community of developers by hindering
their chances of being discovered or recommended through our systems.
Ultimately, they put the end users at risk of making wrong decisions based on
inaccurate, unauthentic information.



Today we are rolling out improved detection and filtering systems to combat such
manipulation attempts. If an install is conducted with the intention to
manipulate an app's placement on Google Play, our systems will detect and filter
it. Furthermore, developers who continue to exhibit such behaviors could have
their apps taken down from Google Play.



In the vast majority of cases, no action will be needed. If you are asking
someone else to promote your app (e.g., third-party marketing agency), we advise
you to make sure that the promotion is based on legitimate practices. In case of
questions, please check out the href="https://developer.android.com/support.html?utm_campaign=android_discussion_playstore_103116&utm_source=anddev&utm_medium=blog">Developer Support
Resources.



These important changes will help protect the integrity of Google Play, our
developer community, and ultimately our end user. Thank you for your support in
building the world's most trusted store for apps and games!





Readfeed graduates from Google Play’s Early Access beta program & offers some learnings


Guest post by Rajiev Timal, Founder of Readfeed



Readfeed was created to help book lovers around the world share and discuss
their favorite reads with each other more easily. Today, we are excited to
officially launch the href="https://play.google.com/store/apps/details?id=com.readfeedinc.readfeed">Readfeed
app on Google Play. As one of the first online book clubs available only on
Android devices, Readfeed lets you create your virtual bookshelf by adding books
to custom lists, track and share your reading progress with community members,
and see what books others are reading and talking about.




Readfeed has come a long way since we first released the app as beta in Google
Play's Early Access program. As one of the first graduates of the beta program,
we were able to solicit feature requests, identify bugs, locate new and optimize
existing target markets, as well as build a sizable reader community. This
allowed Readfeed to deliver the best possible experience right out of the gate.



As a guest on this blog, we thought it would be helpful to share some important
best practices that we learned from the Early Access program to improve your
products and scale your user base.



Harnessing Feedback Loops



One of the core principles underlying the construction of any successful product
is setting up an effective feedback loop between users and product creators.
Google Play Early access does this automatically. Users show up (sometimes
seemingly out of nowhere), install the app, and leave feedback in the Beta
Feedback section of the developer console. We can then reply in that section or
take the conversation into an email, address the issue, and email users when
it's addressed. Many improvements to Readfeed have been made as a direct result
of this process.



Identifying New Target Markets



One major benefit of Early Access was that it gave us immediate access to a
worldwide audience of readers. We were able to quickly assess the different
book-related markets that existed based on user feedback and interviews done
through email. Since launched in beta, over 1000 people have asked to read free
books. Apparently this need exists in third-world countries and we plan to add
this functionality in a future release.



Identifying Bugs



Bugs plague any app in its early stages. Because of the variety of devices that
Early Access users have, ranging from Android 4.2 rooted devices to the latest
Nexus phones, we were able to identify bugs very quickly. For instance, on
Android 4.2 there was a recurrent crash which was tough for me to identify with
my own devices. After one user emailed me about it, I was able to gather enough
information to resolve the issue and put out an update immediately.



Identifying New Features



Google Play Early Access made it a lot easier to determine what to do next. When
about 10 people request a feature, we know it's immediately important and put it
in the app. One feature that came directly from Early Access feedback was the
ability to rate books without leaving a review.



Community Building



Early Access has allowed us to start building a community. For instance, a
Software tester from the UK who likes books sent me a detailed analysis of all
of Readfeed's bugs. Also, we've witnessed many people take the initiative and
answer others' questions about the app. Because of the critical mass that Google
Play Early Access helps you build, it's easy for communities to form and start
sharing information with each other.



A/B Testing



We now have enough users to A/B test certain parts of the app and get
statistically significant results. This is something that usually takes a long
time to achieve.



There are many other ways Google Play Early Access have helped us, and we're
thankful that Readfeed has had the opportunity to be a part of the program. I
can say without reservation that our current and future product would be in a
very different place had it not been for our inclusion in Early Access.

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 href="https://play.google.com/store/apps/category/HEALTH_AND_FITNESS">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 href="http://www.wtsusa.show/">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 href="https://developers.google.com/awareness/">Awareness API, href="https://developers.google.com/fit/rest/">Fit API, href="https://developers.google.com/identity/sign-in/android/start-integrating">Google
Sign In, and href="https://developers.facebook.com/docs/facebook-login/android">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.




href="https://play.google.com/store/apps/details?id=com.freeletics.lite">Freeletics
personalizes onboarding and the overall app experience based on gender and
fitness level leading to a 58% increase in weekly active
sessions.




href="https://play.google.com/store/apps/details?id=com.skimble.workouts">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.



href="https://play.google.com/store/apps/details?id=com.glow.android">Glow
provides personalized insights that leverage user-inputted data and third party
data from Google Fit to
help couples achieve their fertility goals.



href="https://play.google.com/store/apps/details?id=com.beddit.beddit">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.

Posted by Kacey Fahey, Marketing Programs Manager, Google Play



Interested in growing your app on a global scale? See how two app developers
localized their apps in unique ways to drive revenue and user engagement.



drupe



href="https://play.google.com/store/apps/details?id=mobi.drupe.app&hl=en&e=-EnableAppDetailsPageRedesign">drupe
is a communications app that utilizes the openness of android to build a truly
native experience delivering highly contextual recommendations to their users
across the world.



Key to achieving international growth, drupe has translated their app in 17
languages, and their store listing page in 28 languages. This led to an increase
in conversion and retention rates. Additionally, when entering India, the team
noticed several user reviews requesting integration with a specific messaging
app widely used in the Indian market. Through a combination of this integration,
adding Hindi language translation, and other new features, drupe saw improved
performance. In six months, daily active users increased 300%, and actions per
average daily user increased 25% in the Indian market.



Noom



href="https://play.google.com/store/apps/details?id=com.wsl.noom&hl=en&e=-EnableAppDetailsPageRedesign">Noom
is a health & fitness app that has achieved an 80% increase in international
revenue growth on Android over the past three years by localizing their app with
unique cultural behaviors, cuisines, and local-market coaches.



In addition to translating their app and store listing page, Noom conducted
extensive analysis to determine the right financial model tailored to each
international market. This included evaluation of their competitive landscape
and local health and wellness spending behavior, in addition to running pricing
experiments to determine the optimal offering between subscriptions, IAPs, or a
premium app.

Now available: Android 7.1 Developer Preview



Posted by Dave Burke, VP of Engineering



A couple of weeks ago we announced that a developer preview of Android 7.1 Nougat was on the way. You can get started with this new release today by downloading the SDK and tools. To get the 7.1 release on your eligible device, enroll your device in the Android Beta program. If your device is already enrolled, you'll receive the update automatically.



What’s in the Developer Preview?



The Android 7.1 Developer Preview gives you everything you need to test your app on the new platform or extend it with new features like app shortcuts and image keyboard support. It includes an updated SDK and tools, documentation and samples, as well as emulators and device system images for running your apps on supported devices.



We’re continuing the model we used in N and earlier releases, and with Android 7.1 being an incremental release there are a few differences to highlight:




  • Since 7.1 has already launched on Pixel, we’re delivering the initial Developer Preview at beta quality for the Nexus lineup of devices. The goal is to tease out any device-specific issues.

  • We’ve finalized the new APIs as API Level 25

  • We’ve opened up publishing on Google Play for apps targeting the new API level, so you can update your apps soon as you are ready.



After the initial preview release, we plan to deliver an update in November followed by the final public release to the Android Open Source Project (AOSP) in December. Initially available on Nexus 5X, Nexus 6P, and Pixel C devices, we’ll extend the Developer Preview to other devices in November.





Get your apps ready for Android 7.1



To get started, update to Android Studio 2.2.2 and download API Level 25 platform, emulator system images and tools. The final API Level 25 SDK is available for download through the SDK Manager in Android Studio.



Once you’ve installed the API Level 25 SDK, you can update your project’s compileSdkVersion to 25 to build and test against the new APIs. If you’re doing compatibility testing, we recommend updating your app’s targetSdkVersion to 25 to test your app with compatibility behaviors disabled. For details on how to set up your app with the API Level 25 SDK, see Set up the Preview.



If you’re adding app shortcuts or circular launcher icons to your app, you can use Android Studio’s built-in Image Asset Studio to quickly help you create icons of different sizes that meet the material design guidelines.



The Google APIs Emulator System images shipped with the Android API Level 25 SDK include support for round icons and the new Google Pixel Launcher. The Google API system image allows you to test how your app’s circular app icons look in devices that support circular icons. Also, if you are developing live wallpapers, you can also use the the new system images with the Android Emulator to test the enhanced preview metadata in Android 7.1.



To help you add image keyboard support, you can use the Messenger and Google Keyboard apps included in the preview system images for testing as they include support for this new API.



Along with the API Level 25 SDK, we have also updated the Android Support Library to 25.0.0. The new version lets you add image keyboard support with compatibility back to API level 13. It also introduces BottomNavigationView widget, which implements the bottom navigation pattern from the material design guidelines.



For details on API Level 25 check out the API diffs and the updated API reference on the developer preview site.










Image keyboard support on Nexus 6P

You can use the Android Emulator in Android Studio to test your circular app icons & shortcuts in a launcher



App shortcuts on Nexus 6P

You can use the Image Asset tool to quickly create circular icon assets.







Publish your apps to alpha, beta or production channels in Google Play



Since the Android 7.1 APIs are final, you can publish updates compiling with, and optionally targeting, API 25 to Google Play. You can now publish app updates that use API 25 to your alpha, beta, or even production channels in the Google Play Developer Console. In this way, push your app updates to users whose devices are running Android 7.1, such as Pixel and Android Beta devices.

How to Get Android 7.1 Developer Preview on Your Eligible Device



If you are already enrolled in the Android Beta program, then your eligible enrolled devices will get the Android 7.1 Developer Preview update right away, no action is needed on your part. If you aren’t yet enrolled in Android Beta, the easiest way to get started is to visit android.com/beta and opt-in your eligible Android phone or tablet -- you’ll soon receive this (and later) preview updates over-the-air. If you have an enrolled device and do not want to receive the update, just visit Android Beta and unenroll the device. You can also download and flash this update manually.



We welcome your feedback in the Developer Preview issue tracker, N Preview Developer community, or Android Beta community as we work towards the consumer release in December!

Coming soon: Android 7.1 Developer Preview



Posted by Dave Burke, VP of Engineering



Today, we’re taking the wraps off of Android 7.1 Nougat, the latest version of the platform. You probably saw a sneak peek of it at last week’s event. It’s an incremental update based on Android 7.0 but includes new features for consumers and developers — from platform Daydream VR support and A/B system updates to app shortcuts and image keyboard support.



We’ve already been working closely with device makers to get them ready for Android 7.1, and next we’ll give you access to this update so you can start getting your apps ready.



Later this month we’ll be bringing you the Android 7.1 platform as an open Developer Preview, similar to what we did for Android 7.0. You’ll be able to test and build on the new platform and try the latest features.



As always, we’ll deliver the Developer Preview through the Android Beta program, which makes it incredibly easy to participate.



What’s in Android 7.1?



Android 7.1 delivers the productivity, security, and performance of Android 7.0, along with a variety of optimizations and bug fixes, features, and new APIs (API level 25).



For developers, Android 7.1 adds new capabilities to help you drive engagement in your app and deliver an improved user experience, such as:



  • App shortcuts API — lets you surface key actions directly in the launcher and take your users deep into your app instantly. You can create up to 5 shortcuts, either statically or dynamically.

  • Circular app icons support — lets you provide great-looking rounded icon resources that match the look of Pixel and other launchers.

  • Enhanced live wallpaper metadata — lets you provide metadata about your live wallpapers to any picker displaying the wallpapers as a preview. You can show existing metadata such as label, description, and author, as well as a new context URL and title to link to more information.



Android 7.1 also adds these much-requested developer features to the platform:



  • Image keyboard support — expands the types of content that users can enter from their keyboards, letting them express themselves through custom stickers, animated gifs, and more. Apps can tell the keyboard what types of content they accept, and keyboards can deliver all of the images and other content that they offer to the user. For broad compatibility, this API will also be available in the support library.

  • Storage manager Intent — lets an app take the user directly to a new Settings screen to clear unused files and free up storage space on the device.



For carriers and calling apps, the platform includes new APIs to support multi-endpoint calling and new telephony configuration options.






Image keyboard support on Nexus 6P

Image keyboard support: Let users input images and other content directly from a keyboard.



App shortcuts on Nexus 6P

App shortcuts: Use app shortcuts to surface key actions and take users deep into your app instantly.





Get your apps ready



Android 7.1 is an incremental release, but it’s always important to make sure your apps look and run great — especially as devices start to reach consumers.



The Android 7.1 Developer Preview will give you everything you need to test your apps or extend them with new features like shortcuts or keyboard images. Included are the SDK with new APIs, build tools, documentation and samples, as well as emulators and device system images for running your apps on supported Nexus devices. We’ll also include a launcher and apps that support app shortcuts, and a keyboard and apps that support keyboard images.



If you want to receive the Developer Preview automatically, visit Android Beta and enroll your device. If you previously enrolled a device and haven’t unenrolled, your device will receive the update. If you already enrolled but don’t want to receive the update, visit Android Beta to unenroll the device as soon as possible.



Initially, we’ll offer the Developer Preview for Nexus 5X, Nexus 6P, and Pixel C devices, extending to other supported devices by the end of the preview. At the final release of the Android 7.1.x platform, due in early December, we’ll roll out updates to the full lineup of supported devices — Nexus 6, 5X, 6P, 9, Player, Pixel C, and supported Android One devices — as well as Pixel and Pixel XL devices.



Coming to consumer devices soon



We’re working with our partners to bring Android 7.1 to devices in the ecosystem over the months ahead, so we recommend downloading the Android 7.1 Developer Preview as soon as it’s available. Test your apps for compatibility and optimize them to look their best, such as by providing circular app icons and adding app shortcuts.



Meanwhile, stay tuned, we’ll be sharing more details about the Developer Preview soon!
