Improvements to Sign-In with Google Play services 8.3

Posted by Laurence Moroney, Developer Advocate

With Google Play services 8.3, we’ve been hard at work to provide a greatly improved sign-in experience for developers that want to build apps that sign their users in with Google. To help you better understand some of these changes, this is the first in a series of blog posts about what’s available to you as a developer. In this post, we’ll discuss the changes to the user experience, and how you can use them in your app, as well as updates to the API to make coding Sign-In with Google more straightforward. On Android Marshmallow, this new Sign-In API has removed any requirement for device permissions, so there is no need to request runtime access to the accounts on the device, as was the case with the old API.

User Experience Improvements

We’ve gotten lots of feedback from developers about the user experience of using Google’s social sign-in button. Many of you noted that it took too many steps and was confusing for users. Typically, the experience is that the user touches a sign in button, and they are asked to choose an account. If that account doesn’t have a Google+ profile, they need to create one, and after that they have to give permissions based on the type of information that the app is asking for. Finally, they get to sign in to the app.

With the new API, the default set of permissions that the app requests has been reduced to basic profile information and optionally email address as demonstrated here. This introduces opportunities for much streamlined user experience: the first improvement here is in the presentation of the button itself. We had received feedback that the Google+ branding on the Sign-In button made it feel like the user would need to share Google+ data, which most apps don’t use. As such, the SignInButton has been rebranded with the reduced scopes -- it now reads ‘Sign In with Google’, and follows the standard Google branding for use with basic profile information.

After this, the user flow is also more straightforward. Instead of subsequent screens where a Google account is picked based on the email addresses registered on the device, followed by a potential ‘Create Google+ Profile’ dialog, followed by a permissions consent dialog, like this:

The user experience has changed to a single step, where the user chooses their account and gives consent. If they don’t have a Google+ profile, they don’t need to create one, eliminating that step. Additional consent dialogs come later, and are best requested in context so that the user understand why you might ask for access to their calendar or contact, and they are only prompted at the time that this data is needed.

We hope that a streamlined, one-tap, non-social sign-in option with additional OAuth permissions requested in context will help improve your sign-in rates and make it a breeze to sign-in with Google.

Check out some live apps that use the new API, including Instacart, NPR One, and Bring!

In the next post we’ll build on this by looking at some of the changes in the API to make coding apps that use Sign-In with Google even easier.

What’s new in Google Play services 8.3

Posted by Laurence Moroney, Developer Advocate

We’re delighted to announce the availability of Google Play services 8.3. There’s a lot of new information to share with you about what’s available to you in this release.

A big part of this release is focused on user identity. We’ve revamped the Sign In with Google APIs to make implementation simpler and provide users a streamlined experience. First off, the new Google Sign-In no longer requires the device accounts permissions, a big win when you start to develop for Marshmallow. The API also supports the latest Google branding. When using Google Play services 8.3, you’ll find a SignInButton that looks like this with the default scopes:

Previously, users would have to touch a sign in button, and then follow several steps (i.e. selecting account, giving permission to access profile information, and possibly needing to create a Google+ account). With Google Play services 8.3, only one tap is needed for basic profile access.

You can check out the documentation for the new API here.

And to make signing in easier across devices, whether you use Google Sign-In or still have password-based authentication, the Smart Lock APIs received some important updates. We’ve added a new API method to show a dialog that helps your user select a previously-used email address to pre-fill sign in or up forms easily: check out getHintPicker (sample code). This doesn’t require any device permissions and provides an alternative to a picker you may have previously populated from accounts on the device, which would now require a runtime permission with Marshmallow.

You can use this hint information to populate an entire sign-up form with name, email address, and profile picture with one tap, or even direct the user into a sign-in or sign-up flow intelligently based on their email address. Better yet, if the entry the user picked matches an account on the device, Google can provide a verified email address in the hint, which you can use to skip email verification and authenticate the user if your system can support ID tokens, similar to Google Sign-In.

For determining location, Google Play services provides a Fused Location Provider (FLP) which abstracts the underlying location sensors, such as GPS, WiFi, and the cell radio signal, into a single easy-to-use API. We’ve made some improvements to the FLP when it comes to batching. Prior to version 8.3, the batch location APIs would allow the FLP to save power by consolidating network traffic, but when an app removed a batching location request, the batch would be cleared. You may not want this behavior, so we’ve added an API that can return any batched locations immediately. Check the flushLocations and removeLocationUpdates method calls on the FusedLocationProviderApi for more details.

App Invites is a technology that enables your users to share your app with people they know. If you build using App Invites, Google Play services 8.3 has an update that will make coding much simpler. Now, you can use the AppInvite.AppInviteApi.getInvitation() method. This will set up a ResultCallback that you can use to launch your deep link activity, drastically simplifying your code.

The Play game services Player Stats API also gets an update. The latest version now includes a new signal for the probability that a player is about to churn. Developers can use this signal to offer special promotions to improve retention. For example, a developer could provide a discount on a power-up for players that are at risk of churning.

Finally, if you are developing for wearables, you’ll know that battery life and optimization of power usage are critical in having a great user experience. With Google Play services 8.3, we’ve updated the DataApi to allow for urgency in how data items are synced. Now, a priority can be added to the data item to determine when it should be synced. For example, if you are building an app that requires immediate syncing, such as a remote control app, it can still be done immediately by calling setUrgent(), but for something such as updating your contacts, you could tolerate some delay. Non-urgent DataItems may be delayed for up to 30 minutes, but you can expect that in most cases they will be delivered within a few minutes. Low priority is now the default, so setUrgent() is needed to obtain the previous timing.

Filter support has been added to listeners in the Android Wear API, allowing listeners to only receive a subset of changes on both phones and watches. Listeners registered in the Android manifest should be filtered to only receive events that require launching the process, with the remaining events being delivered to live listeners added via methods such as addListener(). This reduces the need for listeners to filter out uninteresting events, making applications and the system more efficient.

That’s it for this release of Google Play services. To learn more, visit the Google Developers site.

Support for 100MB APKs on Google Play

Posted by Kobi Glick, Google Play team

Smartphones are powerful devices that can support diverse tasks from graphically intensive games to helping people get work done from anywhere. We understand that developers are challenged with delivering a delightful user experience that maximizes the hardware of the device, while also ensuring that their users can download, install, and open the app as quickly as possible. It’s a tough balance to strike, especially when you’re targeting diverse global audiences.

To support the growing number of developers who are building richer apps and games on Google Play, we are increasing the APK file size limit to 100MB from 50MB. This means developers can publish APKs up to 100MB in size, and users will see a warning only when the app exceeds the 100MB quota and makes use of Expansion Files. The default update setting for users will continue to be to auto-updating apps over Wi-Fi only, enabling users to access higher quality apps and games while conserving their data usage.

Even though you can make your app bigger, it doesn’t always mean you should. Remember to keep in mind the following factors:

• Mobile data connectivity: Users around the world have varying mobile data connectivity speeds. Particularly in developing countries, many people are coming online with connections slower than those of users in countries like the U.S. and Japan. Users on a slow connection are less likely to install an app or game that is going to take a long time to download.
• Mobile data caps: Many mobile networks around the world give users a limited number of MB that they can download each month without incurring additional charges. Users are often wary of downloading large files for fear of exceeding their limits.
• App performance: Mobile devices have limited RAM and storage space. The larger your app or game, the slower it may run, particularly on older devices.
• Install time: People want to start using your app or game as quickly as possible after tapping the install button. Longer wait times increase the risk they’ll give up.

We hope that, in certain circumstances, this file size increase is useful and enables you to build higher quality apps and games that users love.

Telltale Games share their tips for success on Android TV

Lily Sheringham, Developer Marketing at Google Play

Editor’s note: This is another post in our series featuring tips from developers finding success on Google Play. This week, we’re sharing advice from Telltale Games on how to create a successful game on Android TV. -Ed.

With new Android hardware being released from the likes of Sony, Sharp, and Philips amongst others, Android TV and Google Play can help you bring your game to users right in their living rooms through a big screen experience.

The recent Marshmallow update for Android TV means makes it easier than ever to extend your new or existing games and apps for TV. It's important to understand how your game is presented in the user interface and how it can help users get to the content they want quickly.

Telltale Games is a US-founded game developer and publisher, based in San Francisco, California. They’re well known for the popular series ‘The Walking Dead’ and ‘Game of Thrones‘ which was created in partnership with HBO.

Zac Litton, VP of Technology at Telltale Games, shares his tips for creating and launching your games with Android TV.

Tips for launching successful games on Android TV

1. Determine the Device for Android TV: Determine what device your game is running on by using the UiModeManager.getCurrentModeType() method. If the device is running in television mode, you can declare what to display as the launch point of the game on the Android TV itself (Configuration). Add the LEANBACK_LAUNCHER filter category to one of your intent-filters to identify your game as being enabled for TV. This is required for your game to be considered a TV app in Google Play.
2. Touchscreen vs TV: TVs don’t have touch screens so make sure you set the touchscreen required flag to false in the manifest as touch is implicitly true by default on Android. This will help avoid your game getting filtered from the TV Play store right out of the gate. Also, check your permissions, as some imply hardware requirements which you may need to override explicitly.
3. Use Hardware APIs: Use the package manager which has System Feature API to enable your game to reason about what capabilities it can and should expose. For example, whether to show the user touch screen controls or game controller controls. You can also make your app location aware using the location APIs available in Google Play services to add location awareness with automated location tracking, geofencing, and activity recognition.
4. Use appropriate controllers: To reach the most users, your app should support a simplified input scheme that doesn’t require a directional pad (D-pad controller). The player needs to be able to use a D-Pad in all aspects of the game—not just controlling core gameplay, but also navigating menus and ads, therefore your Android TV game shouldn’t refer to a touch interface specifically. For example, an Android TV game should not tell a player to "Tap here to continue."
5. Appear in the right place: Make sure you add an android:isGame attribute to the application element of the manifest and set it to true in order to enable the installed game to show up on the correct launcher row, games.
6. Provide home screen banners: Provide a home screen banner for each localization supported, especially if you are an international developer. The banner (320 x 180) is the game launch point that appears on the TV home screen on the games row.
7. Use a TV image for your Store Listing: Be sure you provide at least one TV screen shot on your Store Listing page. Then include a high res icon, feature graphic, promo graphic and TV banner.
8. Improve visibility through ‘search’ and ‘recommendations’: Android TV uses the Android search interface to retrieve content data from installed apps and games, and deliver search results to the user. Implement a ContentProvider to show instant suggestions to the user, and a SearchManager to deep link your game’s content.
9. Set appropriate pricing and distribution: Check “Distribute to Android TV” in the relevant section in the Developer Console. This will trigger a review by Google to ensure your game meets the minimum requirements for TV.
10. Guide the user: Use a tutorial to guide the player into the game mechanics and provide an input reference to the user based on the input control they are using.

With the recently released Android TV codelab and online class from Udacity, you can learn how to convert your existing mobile game into Android TV in just four hours. Find out more about how to build games for Android TV and how you to publish them using familiar tools and processes in Google Play.

Play Games Loot Drop for Developers

Posted by Ben Frenkel, Product Manager Google Play Games

Launched last March, Player Analytics is already becoming an important tool for many game developers, helping them to manage their games businesses and optimize in-game player behavior. Today we’re expanding Player Analytics with two new analytics reports that give you better visibility into time-based player activity and custom game events. We’re also introducing a new Player Stats API to let you tune your game experience for specific segments of players across the game lifecycle. Along with those, we’re rolling out a new version of our C++/iOS SDKs and Unity plug-in and giving you better tools to manage repeating Quests.

New useful reports for developers

We are launching two new reports later this week in the Play Games developer console: the Player Time Series Explorer and the Events Viewer. We’ve also made improvements to our player retention report.

Player Time Series Explorer

Ever wondered what your players are doing in the first few minutes of gameplay? What happens just before players spend or churn? The time-series explorer lets you understand what happens in these critical moments for your players.

For example, you carefully built out the first set of experiences in your game, but are surprised by how many players never get through even the first set of challenges. With the Player Time Series Explorer, you can now see which challenges are impeding player progress most, and make targeted improvements to decrease the rate of churn. Learn more.

Customize settings to explore player time series

Select from a list of preset questions

Find out what happens before your players spend for the first time

Select “What happens before first spend” to see what happens just before your players spend for the first time. Time series are aligned by first spend event so you can easily explore what happened just before and after first purchase.

Find out what happens before your players churn

Select “What happens before churn” to see what happens before your players stop playing. In the example below, all the churn events are right aligned to make it easier to compare player time series.

Hovering over events shows you additional details

You can see more details for all event types by holding your cursor over the event’s shape. In this example, you can see that “Player 03” spent $4.99 after earning six achievements. Hovering over the achievement shapes will show you which specific achievements were earned.

Events Viewer

Now you can create your own reports based on your custom Play Games’ events. You can select multiple events to display and bookmark the report for easy access. Learn more.

Here’s an example showing how a developer can compare the rates at which Players are entering contests, winning, and almost winning. This report would identify opportunities to improve the balance of its contest modes. You can then bookmark the settings so you can easily track improvements.

28x28 day retention grid

We added a 28-day-by-28-day retention grid to help you compare retention rates across a larger number of new user cohorts.

Tailor player experiences with the Player Stats API

Stats and reports give you insights into your what your players are doing, but wouldn’t it be nice to take action on those insights in your game? That’s what the Player Stats API is all about. The Player Stats API lets you tailor player experiences to specific segments of players across the game lifecycle. Player segments are based on player progression, spend, and engagement.

Here are some examples of what you can do with Player Stats API:

• For highly engaged players that just aren’t spending, you can show them special bonuses that are aimed at recruiting others to play instead of spending
• For your most prolific spenders, you can provide occasional free gifts and upgrades
• For users that haven’t found their stride in your game, you can show them a video that directs them to community features, like clan attacks or alliances, that drive deeper engagement
• For players that have been away from the game for a while, you can give them a welcome back message that acknowledges impressive accomplishments, and award a badge designed to encourage return play

The Player Stats API is launching in the next few weeks.

C++/iOS SDK and Unity Plug-in updates

iOS support for Play game services just got a lot better. This update includes improved CocoaPods support, which will make it easier to configure Play game services in Xcode. This also means you’ll have a much easier time building for iOS using the Unity plug-in as well.

The latest build of the C++/iOS SDKs is now built on the new Google Sign-In framework, which adds support for authentication via multiple Google apps, including Gmail and YouTube. More importantly, if a player does not have any applicable Google apps installed, the Sign-In framework will bring up a webview within the app for authentication. Opening up a webview inside the app, instead of switching to a separate browser instance, makes for a much better user experience, and addresses a top developer request. For more on the new Google Sign-in library on iOS, check out this video. Learn more.

Improved Quests

Quests are a great way of engaging your players with new goals, and with this update we have made managing Quests easier with the introduction of repeating Quests. You can create Quests that run weekly or monthly by checking the repeating quest box. This will make it easier for you to engage your players with regularly occurring challenges. Repeating Quests will be launching in the next few weeks.

If you have previously integrated Quests, you can easily convert them into repeating quests by following two easy steps.

1. Go to Quests section of developer console, and open up an existing Quest. Click the copy Quest button at the top of the page

2. Scroll down to the Schedule section of the Quest form, check the “Repeating quest” box, select between monthly and weekly quests under “Repeats”, and leave the “Ends:” field set to “Never”. After hitting save, you are done! From then on, the quest will run weekly or monthly until you decide to end it.

Games developer, Dots, share their Do’s and Don’ts for improving your visibility on Google Play

Posted by Lily Sheringham, Developer Marketing at Google Play
Editor’s note: A few weeks ago we shared some tips from game developer, Seriously, on how they’ve been using notifications successfully to drive ongoing engagement. This week, we’re sharing tips from Christian Calderon at US game developer, Dots, on how to successfully optimize your Play Store Listing. -Ed.

A well thought-out Google Play store listing can significantly improve the discoverability of your app or game and drive installations. With the recent launch of Store Listing Experiments on the Google Play Developer Console, you can now conduct A/B tests on the text and graphics of your store listing page and use the data to make more informed decisions.

Dots is a US-founded game developer which released the popular game, Dots, and its addictive sequel, TwoDots. Dots used its store listings to showcase its brands and improve conversions by letting players know what to expect.

Christian Calderon, Head of Marketing for Dots, shared his top tips with us on store listings and visibility on Google Play.

Do’s and Don’ts for optimizing store listings on Google Play

Do’s	Don’ts
Do be creative and unique with the icon. Try to visually convince the user that your product is interesting and in alignment with what they are looking for.	Don’t spam keywords in your app title. Keep the title short, original and thoughtful and keep your brand in mind when representing your product offering.
Do remember to quickly respond to reviews and implement a scalable strategy to incorporate feedback into your product offering. App ratings are important social proof that your product is well liked.	Don’t overload the ‘short description’. Keep it concise. It should be used as a call-to-action to address your product’s core value proposition and invite the user to install the application. Remember to consider SEO best practices.
Do invest in a strong overall paid and organic acquisition strategy. More downloads will make your product seem more credible to users, increasing the likeliness that a user will install your app.	Don’t overuse text in your screenshots. They should create a visual narrative for what’s in your game and help users visualize your product offering, using localization where possible.
Do link your Google Play store listing to your website, social media accounts, press releases and any of your consumer-facing channels that may drive organic visibility to your target market. This can impact your search positioning.	Don’t have a negative, too short or confusing message in your “What’s New” copy. Let users know what updates, product changes or bug fixes have been implemented in new versions. Keep your copy buoyant, informative, concise and clear.
Do use Video Visualization to narrate the core value proposition. For TwoDots, our highest converting videos consist of gameplay, showcasing features and events within the game that let the player know exactly what to expect.	Don’t flood the user with information in the page description. Keep the body of the page description organized and concise and test different structural patterns that works best for you and your product!

Use Google Play Store Listing Experiments to increase your installs

As part of the 100 Days of Google Dev video series, Kobi Glick from the Google Play team explains how to test different graphics and text on your app or game’s Play Store listing to increase conversions using the new Store Listing Experiments feature in the Developer Console.

Get the Do’s and Don’ts for Notifications from Game Developer Seriously

Posted by Lily Sheringham, Developer Marketing at Google Play

Editor’s note: We’ve been talking to developers to find out how they’ve been achieving success on Google Play. We recently spoke to Reko Ukko at Finnish mobile game developer, Seriously, to find out how to successfully use Notifications.

Notifications on Android let you send timely, relevant, and actionable information to your users' devices. When used correctly, notifications can increase the value of your app or game and drive ongoing engagement.

Seriously is a Finnish mobile game developer focused on creating entertaining games with quality user experiences. They use push notifications to drive engagement with their players, such as helping players progress to the next level when they’ve left the app after getting stuck.

Reko Ukko, VP of Game Design at Seriously, shared his tips with us on how to use notifications to increase the value of your game and drive ongoing engagement.

Do’s and don’ts for successful game notifications

Do’s	Don’ts
Do let the user get familiar with your service and its benefits before asking for permission to send notifications.	Don’t treat your users as if they’re all the same - identify and group them so you can push notifications that are relevant to their actions within your app.
Do include actionable context. If it looks like a player is stuck on a level, send them a tip to encourage action.	Don’t spam push notifications or interrupt game play. Get an understanding of the right frequency for your audience to fit the game.
Do consider re-activation. If the player thoroughly completes a game loop and could be interested in playing again, think about using a notification. Look at timing this shortly after the player exits the game.	Don’t just target players at all hours of the day. Choose moments when players typically play games – early morning commutes, lunch breaks, the end of the work day, and in the evening before sleeping. Take time zones into account.
Do deep link from the notification to where the user expects to go to based on the message. For example. if the notification is about "do action X in the game now to win", link to where that action can take place.	Don’t forget to expire the notifications if they’re time-limited or associated with an event. You can also recycle the same notification ID to avoid stacking notifications for the user.
Do try to make an emotional connection with the player by reflecting the style, characters, and atmosphere of your game in the notification. If the player is emotionally connected to your game, they’ll appreciate your notifications and be more likely to engage.	Don’t leave notifications up to guess work. Experiment with A/B testing and iterate to compare how different notifications affect engagement and user behavior in your app. Go beyond measuring app opening metrics – identify and respond to user behavior.

Experiment with notifications yourself to understand what’s best for your players and your game. You can power your own notifications with Google Cloud Messaging, which is free, cross platform, reliable, and thoughtful about battery usage. Find out more about developing Notifications on Android.

Iterate faster on Google Play with improved beta testing

Posted by Ellie Powers, Product Manager, Google Play

Today, Google Play is making it easier for you to manage beta tests and get your users to join them. Since we launched beta testing two years ago, developers have told us that it’s become a critical part of their workflow in testing ideas, gathering rapid feedback, and improving their apps. In fact, we’ve found that 80 percent of developers with popular apps routinely run beta tests as part of their workflow.

Improvements to managing a beta test in the Developer Console

Currently, the Google Play Developer Console lets developers release early versions of their app to selected users as an alpha or beta test before pushing updates to full production. The select user group downloads the app on Google Play as normal, but can’t review or rate it on the store. This gives you time to address bugs and other issues without negatively impacting your app listing.

Based on your feedback, we’re launching new features to more effectively manage your beta tests, and enable users to join with one click.

• ^NEW! Open beta – Use an open beta when you want any user who has the link to be able to join your beta with just one click. One of the advantages of an open beta is that it allows you to scale to a large number of testers. However, you can also limit the maximum number of users who can join.
• ^NEW! Closed beta using email addresses – If you want to restrict which users can access your beta, you have a new option: you can now set up a closed beta using lists of individual email addresses which you can add individually or upload as a .csv file. These users will be able to join your beta via a one-click opt-in link.
• Closed beta with Google+ community or Google Group – This is the option that you’ve been using today, and you can continue to use betas with Google+ communities or Google Groups. You will also be able to move to an open beta while maintaining your existing testers.

How developers are finding success with beta testing

Beta testing is one of the fast iteration features of Google Play and Android that help drive success for developers like Wooga, the creators of hit games Diamond Dash, Jelly Splash, and Agent Alice. Find out more about how Wooga iterates on Android first from Sebastian Kriese, Head of Partnerships, and Pal Tamas Feher, Head of Engineering.

Kabam is a global leader in AAA quality mobile games developed in partnership with Hollywood studios for such franchises such as Fast & Furious, Marvel, Star Wars and The Hobbit. Beta testing helps Kabam engineers perfect the gameplay for Android devices before launch. “The ability to receive pointed feedback and rapidly reiterate via alpha/beta testing on Google Play has been extremely beneficial to our worldwide launches,” said Kabam VP Rob Oshima.

Matt Small, Co-Founder of Vector Unit recently told us how they’ve been using beta testing extensively to improve Beach Buggy Racing and uncover issues they may not have found otherwise. You can read Matt’s blog post about beta testing on Google Play on Gamasutra to hear about their experience. We’ve picked a few of Matt’s tips and shared them below:

1. Limit more sensitive builds to a closed beta where you invite individual testers via email addresses. Once glaring problems are ironed out, publish your app to an open beta to gather feedback from a wider audience before going to production.
2. Set expectations early. Let users know about the risks of beta testing (e.g. the software may not be stable) and tell them what you’re looking for in their feedback.
3. Encourage critical feedback. Thank people when their criticisms are thoughtful and clearly explained and try to steer less-helpful feedback in a more productive direction.
4. Respond quickly. The more people see actual responses from the game developer, the more encouraged they are to participate.
5. Enable Google Play game services. To let testers access features like Achievements and Leaderboards before they are published, go into the Google Play game services testing panel and enable them.

We hope this update to beta testing makes it easier for you to test your app and gather valuable feedback and that these tips help you conduct successful tests. Visit the Developer Console Help Center to find out more about setting up beta testing for your app.

Android Developer Story: Shifty Jelly drives double-digit growth with material design and expansion to the car and wearables

Posted by Lily Sheringham, Google Play team

Pocket Casts is a leading podcasting app on Google Play built by Australian-based mobile development company Shifty Jelly. The company recently achieved $1 million in sales for the first time, reaching more than 500K users.

According to the co-founder Russell Ivanovic, the adoption of material design played a significant role in driving user engagement for Pocket Casts by streamlining the user experience. Moreover, users are now able to access the app beyond the smartphone -- in the car with Android Auto, on a watch with Android Wear or on the TV with Google Cast. The rapid innovation of Android features helped Pocket Casts increase sales by 30 percent.

We chatted with co-founders and Android developers Russell and Philip Simpson to learn more about how they are growing their business with Android.

Here are some of the features Pocket Casts used:

• Material Design: Learn more about material design and how it helps you create beautiful, engaging apps.
• Android Wear: Extend your app to Android Wear devices with enhanced notifications or a standalone wearable app.
• Android Auto: Extend your app to an interface that’s optimized for driving with Android Auto.
• Google Cast: let your users cast your app’s content to Google Cast devices like Chromecast, Android TV, and speakers with Google Cast built-in.

And check out the Pocket Casts app on Google Play!

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.

Android Developer Story: Wooga’s fast iterations on Android and Google Play

Posted by Leticia Lago, Google Play team

In order to make the best possible games, Wooga works on roughly 40 concepts and prototypes per year, out of which 10 go into production, around seven soft launch, and only two make it to global launch. It’s what they call “the hit filter." For their latest title, Agent Alice, they follow up with new episodes every week to maintain player interest and engagement over time.

The ability to quickly iterate both live and under development games is therefore key to Wooga’s business model — Android and Google Play provide them the tools they need and mean that new features and updates are made on Android first, before they get to other platforms.

Find out more from Sebastian Kriese, Head of Partnerships, and Pal Tamas Feher, Head of Engineering, and learn how the iteration features of Android and Google Play have contributed to successes such as Diamond Dash, Jelly Splash, and Agent Alice.

You can find out more about building successful games businesses on Android and Google Play at Google I/O 2015: in person, on the live stream, or session recordings after the event. Check out the following:

Android Developer Story: The Hunt -- Increased engagement with material design and Google Play

Posted by Laura Della Torre, Google Play team

We've been in San Francisco talking with the team from The Hunt — a style and product sharing community. They've recently lifted the rate at which Android users start hunts to 20 percent after successfully implementing material design in the app, which is a 30 percent improvement over other platforms. As The Hunt’s Product Designer Jenny Davis puts it, “it felt like having a team of design experts on hand,” which lets them focus on what matters to the Android user.

But as we find out, that's not the whole story. Beta testing — managed from the Google Play Developer Console — also allowed them to iterate design and features daily. Based on feedback, they introduced the floating action button, which helped boost new hunts and helpful responses from the community. This speed and freedom is something the team thought possible only with their mobile website, until they started working with the Android tools.

Watch the video to discover more about how design and rapid iteration has been key to building a strong community.

Integrate Play data into your workflow with data exports

Posted by Frederic Mayot, Google Play team

The Google Play Developer Console makes a wealth of data available to you so you have the insight needed to successfully publish, grow, and monetize your apps and games. We appreciate that some developers want to access and analyze their data beyond the visualization offered today in the Developer Console, which is why we’ve made financial information, crash data, and user reviews available for export. We're now also making all the statistics on your apps and games (installs, ratings, GCM usage, etc.) accessible via Google Cloud Storage.

New Reports section in the Google Play Developer Console

We’ve added a Reports tab to the Developer Console so that you can view and access all available data exports in one place.

A reliable way to access Google Play data

This is the easiest and most reliable way to download your Google Play Developer Console statistics. You can access all of your reports, including install statistics, reviews, crashes, and revenue.

Programmatic access to Google Play data

This new Google Cloud Storage access will open up a wealth of possibilities. For instance, you can now programmatically:

• import install and revenue data into your in-house dashboard
• run custom analysis
• import crashes and ANRs into your bug tracker
• import reviews into your CRM to monitor feedback and reply to your users

Your data is available in a Google Cloud Storage bucket, which is most easily accessed using gsutil. To get started, follow these three simple steps to access your reports:

1. Install the gsutil tool.
• Authenticate to your account using your Google Play Developer Console credentials.
2. Find your reporting bucket ID on the new Reports section.
• Your bucket ID begins with: pubsite_prod_rev (example:pubsite_prod_rev_1234567890)
3. Use the gsutil ls command to list directories/reports and gsutil cp to copy the reports. Your reports are organized in directories by package name, as well as year and month of their creation.

Read more about exporting report data in the Google Play Developer Help Center.

Note about data ownership on Google Play and Cloud Platform: Your Google Play developer account is gaining access to a dedicated, read-only Google Cloud Storage bucket owned by Google Play. If you’re a Google Cloud Storage customer, the rest of your data is unaffected and not connected to your Google Play developer account. Google Cloud Storage customers can find out more about their data storage on the terms of service page.

Android Developer Story: Jelly Button Games grows globally through data driven development

Posted by Leticia Lago, Google Play team

For Jelly Button Games, understanding users is the key to creating and maintaining a successful game, particularly when growth relies on moving into overseas markets. The team makes extensive use of Google Analytics and Google BigQuery to analyze more than 3 billion events each month. By using this data, Jelly Button can pinpoint exactly where, when, and why people play their highly-rated game, Pirate Kings. Feeding this information back into development has driven active daily users up 1500 percent in just five months.

We caught up with Mor Shani, Moti Novo, and Ron Rejwan — some of the co-founders — in Tel Aviv, Israel, to discover how they created an international hit and keep it growing.

Learn about Google Analytics and taking your game to an international audience:

• Analyze — discover the power of data from the Google Play Developer Console and Google Analytics.
• Query — find out how Google BigQuery can help you extract the essential information you need from millions or billions of data points.
• Localize — guide the localization of your app with best practices and tools.

Helping developers connect with families on Google Play

Posted by Eunice Kim, Product Manager, Google Play

There are thousands of Android developers creating experiences for families and children — apps and games that broaden the mind and inspire creativity. These developers, like PBS Kids, Tynker and Crayola, carefully tailor their apps to provide high quality, age appropriate content; from optimizing user interface design for children to building interactive features that both educate and entertain.

Google Play is committed to the success of this emerging developer community, so today we’re introducing a new program called Designed for Families, which allows developers to designate their apps and games as family-friendly. Participating apps will be eligible for upcoming family-focused experiences on Google Play that will help parents discover great, age-appropriate content and make more informed choices.

Starting now, developers can opt in their app or game through the Google Play Developer Console. From there, our team will review the submission to verify that it meets the Designed for Families program requirements. In the coming weeks, we’ll be adding new ways to promote family content to users on Google Play — we’ll have more to share on this soon.

Power Great Gaming with New Analytics from Play Games

By Ben Frenkel, Google Play Games team

A few weeks ago at the Game Developers Conference (GDC), we announced Play Games Player Analytics, a new set of free reports to help you manage your games business and understand in-game player behavior. Today, we’re excited to make these new tools available to you in the Google Play Developer Console.

Analytics is a key component of running a game as a service, which is increasingly becoming a necessity for running a successful mobile gaming business. When you take a closer look at large developers that do this successfully, you find that they do three things really well:

• Manage their business to revenue targets
• Identify hot spots in their business metrics so they can continuously focus on the game updates that will drive the most impact
• Use analytics to understand how players are progressing, spending, and churning

“With player engagement and revenue data living under one roof, developers get a level of data quality that is simply not available to smaller teams without dedicated staff. As the tools evolve, I think Google Play Games Player Analytics will finally allow indie devs to confidently make data-driven changes that actually improve revenue.”

Kevin Pazirandeh
Developer of Zombie Highway 2

With Player Analytics, we wanted to make these capabilities available to the entire developer ecosystem on Google Play in a frictionless, easy-to-use way, freeing up your precious time to create great gaming experiences. Small studios, including the makers of Zombie Highway 2 and Bombsquad, have already started to see the benefits and impact of Player Analytics on their business.

Further, if you integrate with Google Play game services, you get this set of analytics with no incremental effort. But, for a little extra work, you can also unlock another set of high impact reports by integrating Google Play game services Events, starting with the Sources and Sinks report, a report to help you balance your in-game economy.

If you already have a game integrated with Google Play game services, go check out the new reports in the Google Play Developer Console today. For everyone else, enabling Player Analytics is as simple as adding a handful of lines of code to your game to integrate Google Play game services.

Manage your business to revenue targets

Set your spend target in Player Analytics by choosing a daily goal

To help assess the health of your games business, Player Analytics enables you to select a daily in-app purchase revenue target and then assess how you're doing against that goal through the Target vs Actual report depicted below. Learn more.

Identify hot spots using benchmarks with the Business Drivers report

Ever wonder how your game’s performance stacks up against other games? Player Analytics tells you exactly how well you are doing compared to similar games in your category.

Metrics highlighted in red are below the benchmark. Arrows indicate whether a metric is trending up or down, and any cell with the icon can be clicked to see more details about the underlying drivers of the change. Learn more.

Track player retention by new user cohort

In the Retention report, you can see the percentage of players that continued to play your game on the following seven days after installing your game.

Learn more.

See where players are spending their time, struggling, and churning with the Player Progression report

Measured by the number of achievements players have earned, the Player Progression funnel helps you identify where your players are struggling and churning to help you refine your game and, ultimately, improve retention. Add more achievements to make progression tracking more precise.

Learn more.

Manage your in-game economy with the Sources and Sinks report

The Sources and Sinks report helps you balance your in-game economy by showing the relationship between how quickly players are earning or buying and using resources.

For example, Eric Froemling, one man developer of BombSquad, used the Sources & Sinks report to help balance the rate at which players earned and spent tickets.

Read more about Eric’s experience with Player Analytics in his recent blog post.

To enable the Sources and Sinks report you will need to create and integrate Play game services Events that track sources of premium currency (e.g., gold coins earned), and sinks of premium currency (e.g., gold coins spent to buy in-app items).
