After nearly six months of development, Android Studio 3.4 is ready to download today on the stable release channel. This is a milestone release of the Project Marble effort from the Android Studio team. Project Marble is our focus on making the fundamental features and flows of the Integrated Development Environment (IDE) rock-solid. On top of many performance improvements and bug fixes we made in Android Studio 3.4, we are excited to release a small but focused set of new features that address core developer workflows for app building & resource management.
Part of the effort of Project Marble is to address user facing issues in core features in the IDE. At the top of the list of issues for Android Studio 3.4 is an updated Project Structure Dialog (PSD) which is a revamped user interface to manage dependencies in your app project Gradle build files. In another build-related change, R8 replaces Proguard as the default code shrinker and obfuscator. To aid app design, we incorporated your feedback to create a new app resource management tool to bulk import, preview, and manage resources for your project. Lastly, we are shipping an updated Android Emulator that takes less system resources, and also supports the Android Q Beta. Overall, these features are designed to make you more productive in your day-to-day app development workflow.
Alongside the stable release of Android Studio 3.4, we recently published in-depth blogs on how we are investigating & fixing a range of issues under the auspices of Project Marble. You should check them out as you download the latest update to Android Studio:
The development work for Project Marble is still on-going, but Android Studio 3.4 incorporates productivity features and over 300 bug & stability enhancements that you do not want to miss.

The Android Ice Cream Sandwich (ICS) platform is seven years old and the active device count has been below 1% for some time. Consequently, we are deprecating support for ICS in future releases of Google Play services. For devices running ICS, the Google Play Store will no longer update Play Services APK beyond version 14.7.99.
What does this mean as an Application developer:
The Google Play services SDK contains the interfaces to the functionality provided by the Google Play services APK, running as background services. The functionality required by the current, released SDK versions is already present on ICS devices with Google Play services and will continue to work without change.
With the SDK version changes earlier this year, each library can be independently released and may update its own minSdkVersion. Individual libraries are not required to change based on this deprecation. Newer SDK components may continue to support API levels 14 and 15 but many will update to require the higher API level. For applications that support API level 16 or greater, you will not need to make any changes to your build. For applications that support API levels 14 or 15, you may continue to build and publish your app to devices running ICS, but you will encounter build errors when updating to newer SDK versions. The error will look like this:
Error:Execution failed for task ':app:processDebugManifest'. > Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 16 declared in library [com.google.android.gms:play-services-FOO:16.X.YY] Suggestion: use tools:overrideLibrary="com.google.android.gms:play_services" to force usage
Unfortunately, the stated suggestion will not help you successfully run your app on older devices. In order to use the newer SDK, you will need to use one of the following options:
1. Target API level 16 as the minimum supported API level.
This is the recommended course of action. To discontinue support for API levels that will no longer receive Google Play services updates, simply increase the minSdkVersion value in your app's build.gradle to at least 16. If you update your app in this way and publish it to the Play Store, users of devices with less than that level of support will not be able to see or download the update. However, they will still be able to download and use the most recently published version of the app that does target their device.
A very small percentage of all Android devices are using API levels less than 16. You can read more about the current distribution of Android devices. We believe that many of these old devices are not actively being used.
If your app still has a significant number of users on older devices, you can use multiple APK support in Google Play to deliver an APK that uses Google Play services 14.7.99. This is described below.
2. Build multiple APKs to support devices with an API level less than 16.
Along with some configuration and code management, you can build multiple APKs that support different minimum API levels, with different versions of Google Play services. You can accomplish this with build variants in Gradle. First, define build flavors for legacy and newer versions of your app. For example, in your build.gradle, define two different product flavors, with two different compile dependencies for the stand-in example play-services-FOO component:
productFlavors { legacy { minSdkVersion 14 versionCode 1401 // Min API level 14, v01 } current { minSdkVersion 16 versionCode 1601 // Min API level 16, v01 } } dependencies { legacyCompile 'com.google.android.gms:play-services-FOO:16.0.0' currentCompile 'com.google.android.gms:play-services-FOO:17.0.0' }
In the above situation, there are two product flavors being built against two different versions of play-services-FOO. This will work fine if only APIs are called that are available in the 16.0.0 library. If you need to call newer APIs made available with 17.0.0, you will have to create your own compatibility library for the newer API calls so that they are only built into the version of the application that can use them:
After building a release APK for each flavor, you then publish them both to the Play Store, and the device will update with the most appropriate version for that device. Read more about multiple APK support in the Play Store.
Today, at the Computer History Museum in Mountain View, CA, we kicked off the Android Dev Summit, taking a look back at the last 10 years of Android and then jumping into some important new features for Android developers. Here's a look at some of the things we shared!
As early as Android 1.6, Android and our partners have contemplated different screen sizes and densities, enabling the platform to power a broad category of form factors and new experiences like Android TV, Android Auto, Wear OS and even Android apps on Chromebooks. Phone screens are an area where Android partners set the bar, introducing "phablets" when phone screens were small. Fast forward to today, when a phablet is... just a phone, a standard size users have come to love.
Now we see a Android device makers creating a new category: Foldables. Taking advantage of new flexible display technology, the screen can literally bend and fold.
There are two variants broadly speaking: two-screen devices and one-screen devices. When folded, foldables look like phones, fitting in your pocket or purse. When unfolded, their defining feature is what we call screen continuity. For example, start a video with the folded smaller screen - and later you can sit down and unfold the device to get a larger tablet-sized screen for a beautiful, immersive experience. As you unfold, the app seamlessly transfers to the bigger screen without missing a beat. We're optimizing Android for this new form factor. And, making changes to help developers everywhere take advantage of the possibilities this creates for amazing new experiences, new ways to engage and delight your users. Tune in to the Foldables session at Dev Summit this week to learn more. Expect to see Foldables coming from several Android manufacturers, including one Samsung previewed today and plans to offer next year.
We made Kotlin a first class language on Android in 2017. This month we had over 118,000 new projects using Kotlin started in Android Studio - from those users who opt in to share metrics. That's a 10X increase from last year. It's become the fastest growing language in terms of growth of number of contributors on GitHub, and voted the #2 most loved language on Stack Overflow. In our surveys, the more developers use Kotlin, the higher their satisfaction.
Last week, JetBrains released the latest version of Kotlin, 1.3, which brings new language features, APIs, bug fixes, and performance improvements:
All of these new features of Kotlin 1.3 will be integrated into the Kotlin-specific APIs that we provide–a majority of which are through KTX extensions as part of Jetpack.
At Google I/O we announced Jetpack, the next generation of tools and Android APIs to accelerate Android application development. Jetpack builds on the foundations laid out by Support Library and Architecture. Already, 80% of top 1,000 apps and games are using one of the new Jetpack libraries in production.
This summer we moved AndroidX - Jetpack's evolution of the original Android Support Library - to public AOSP. This means you can see features and bug fixes implemented in real-time, and contribute to any of the AndroidX libraries. You can learn more about contributing here.
We've been working to get as much feedback and refinement as possible on two new Architecture Component libraries: Navigation and Work Manager, and we plan to move both to Beta this month. The Navigation Architecture Component offers a simplified way to implement Android's navigation principles in your application, using a single Activity. Plus, the new Navigation Editor in Android Studio creates and edits your navigation architecture. This eliminates navigation boilerplate, gives you atomic navigation operations, easier animated transitions and more. WorkManager makes it easy to perform background tasks in the most efficient manner, choosing the most appropriate solution based on the application state and device API level.
Navigation Editor
We're also excited to see Android Slices move to public Search experiments! At I/O this year we introduced Slices, a new way to bring users to your app. Slices are like a mini snippet of your app, where you can surface content and actions. You can book a flight, play a video, or call a ride. Slices is another example where we want to be open very early, but we want to take the time to get it right. We're moving into public EAP this month with Doist, Kayak and others. We'll run experiments surfacing Slices in Google search results. To learn more, there's also a session today at Dev Summit with more info and best practices.
Android Studio is our official IDE for Android development. We asked where do you spend the most time? When we gather data from Android Studio's opted-in users we see that build time are getting faster with every release, sometimes as fast as 20%, but we also see build time getting slower and slower over time. So, how can both things be true? We've been digging in hard to understand.
It turns out build is a pretty complicated ecosystem. Developer choices makes a huge difference. Our developers are using a very broad (and growing) combination of OSes, custom plug-ins, annotation processors, languages. All of these can significantly affect times. In one case, a plugin some users like to add was silently slowing build speeds by up to 45%. Learning this, we realized we need build profiling and analysis tools so you can easily understand what's slowing your build down. We're also investing more in our own plugins to accelerate performance to make sure we continue to improve the performance of core build.
Android Studio 3.3 launches beta 3 today. In coming releases expect to see a strong focus on quality and fundamentals: reducing the number of crashes and hangs, optimizing memory usage, and fixing user-impacting bugs. We also announced today that we're making Android Studio an officially supported IDE on Chrome OS early next year; learn more here.
App sizes have grown dramatically, up 5x since 2012. But larger apps have downsides: lower install conversion rates, lower update rates, and higher uninstalls. This is why we built the Android App Bundle, the new publishing format that serves only the code and resources a user needs to run your app on their specific device; on average apps see 35% size savings compared to a universal APK. The app bundle also saves you time and effort with each release since you don't need to use incomplete solutions like multi-APK. Android Studio 3.2 brought full IDE support of app bundles, and there are now thousands of app bundles in production totaling billions of installs, including Google's apps like YouTube, Google Maps, Google Photos, and Google News.
The app bundle now supports uncompressed native libraries; with no additional developer work needed, the app bundle now makes apps using native libraries an average of 8% smaller to download and 16% smaller on disk on M+ devices.
Once you switch to the app bundle you can also start modularizing your app. With dynamic feature modules, you can load any app functionality on demand instead of at install time. You don't need to keep big features that are only used once, on every single device forever; dynamic features can be installed and uninstalled dynamically when your app requests them.
We've heard that you'd like more controls to ensure that users are running the latest and greatest version of your app. To address this, we're launching an In-app Updates API. We're testing the API with early access partners and will be launching it to all developers soon.
You'll have two options with this API; the first is a full-screen experience for critical updates when you expect the user to wait for the update to be applied immediately. The second option is a flexible update, which means the user can keep using the app while the update is downloaded. You can completely customize the update flow so it feels like part of your app.
We're also making instant apps easier than ever to adopt. We recently made using web URLs optional, enabling you to take your existing play store deep link traffic and send users to your instant experience if it's available. Additionally, we've raised the instant app size limit to 10MB for the Try Now button on the Play Store and web banners to make it even easier to adopt.
In the Android Studio 3.3 beta, you can now build an instant-enabled app bundle. This means that you can now build and deploy both your Instant and installed experiences from a single Android Studio project, and include them in a single Android App Bundle. You only have to upload just ONE artifact for both instant and installed app.
As developers, your feedback has been critical in shaping these investment areas; you are part of how we work, from early ideas, to EAPs and canaries, Beta, and iterating after launch. We hope you join us for the next two days whether you're watching the 30+ sessions on the livestream, joining social, or with us in-person in Mountain View. From the team, a sincere thank you for all your thoughtful feedback and contributions. We hope you enjoy Android Dev Summit.
Today, Android Studio 3.2 is available for download. Android Studio 3.2 is the best way for app developers to cut into the latest Android 9 Pie release and build the new Android App bundle. Since announcing this update of Android Studio at Google I/O '18, we have refined and polished 20+ new features and focused our efforts on improving the quality for this stable release of Android Studio 3.2.
Every developer should use Android Studio 3.2 to transition to using an Android App Bundle, the new app publishing format. With very minimal work, you can generate an app bundle with Android Studio. Once you upload your app bundle to Google Play you can distribute smaller, optimized apps to your users. Early adopters have already seen between 11% - 64% in app size savings with app bundles over the legacy APK app size.
Another feature you do not want to miss is the Energy Profiler. This new profiler gives you a set of tools that will help you diagnose and improve the energy impact of your app. Better device battery life is one of the top most user requests, and with the Energy Profiler in Android Studio 3.2, you can do your part in improving device battery life by making sure your app is using the right amount of energy at the right time.
Lastly, you should also check out the new Android Emulator Snapshots feature. By using this feature, you can quickly take a snapshot of the current state of your emulator which includes the current state of the screen, apps, and settings. You can resume or boot into your emulator snapshot in under 2 seconds. For any app developer looking for super- fast boot times, or seeking to run tests in a predictable Android environment, Android Emulator Snapshots is a game changing feature for app development
On top of these major features, there are 20 new features plus many under-the-hood quality refinements in Android Studio 3.2. By using Android Studio 3.2, you can also develop for the latest technologies ranging from Android Jetpack, to the latest in Google Artificial Intelligence (AI) APIs with Android Slices.
Thank you to those who gave your early feedback on both the canary and beta releases. Your feedback helped us improve the quality and features in Android Studio 3.2. If you are ready for the next stable release, and want to use a new set of productivity features, Android Studio 3.2 is ready to download for you to get started.
Below is a full list of new features in Android Studio 3.2, organized by key developer flows.

The Media Controller Test (MCT) app is a powerful tool that allows you to test the intricacies of media playback on Android, and it's just gotten even more useful. Media experiences including voice interactions via the Google Assistant on Android phones, cars, TVs, and headphones, are powered by Android MediaSession APIs. This tool will help you verify your integrations. We've now added a new verification testing framework that can be used to help automate your QA testing.
The MCT is meant to be used in conjunction with an app that implements media APIs, such as the Universal Android Music Player. The MCT surfaces information about the media app's MediaController, such as the PlaybackState and Metadata, and can be used to test inter-app media controls.
The Media Action Lifecycle can be complex to follow; even in a simple Play From Search request, there are many intermediate steps (simplified timeline depicted below) where something could go wrong. The MCT can be used to help highlight any inconsistencies in how your music app handles MediaController TransportControl requests.
Previously, using the MCT required a lot of manual interaction and monitoring. The new verification testing framework offers one-click tests that you can run to ensure that your media app responds correctly to a playback request.
To access the new verification tests in the MCT, click the Test button next to your desired media app.
The next screen shows you detailed information about the MediaController, for example the PlaybackState, Metadata, and Queue. There are two buttons on the toolbar in the top right: the button on the left toggles between parsable and formatted logs, and the button on the right refreshes this view to display the most current information.
By swiping to the left, you arrive at the verification tests view, where you can see a scrollable list of defined tests, a text field to enter a query for tests that require one, and a section to display the results of the test.
As an example, to run the Play From Search Test, you can enter a search query into the text field then hit the Run Test button. Looks like the test succeeded!
Below are examples of the Pause Test (left) and Seek To test (right).
The MCT now also works on Android TV! For your media app to work with the Android TV version of the MCT, your media app must have a MediaBrowserService implementation. Please see here for more details on how to do this.
On launching the MCT on Android TV, you will see a list of installed media apps. Note that an app will only appear in this list if it implements the MediaBrowserService.
Selecting an app will take you to the testing screen, which will display a list of verification tests on the right.
Running a test will populate the left side of the screen with selected MediaController information. For more details, please check the MCT logs in Logcat.
Tests that require a query are marked with a keyboard icon. Clicking on one of these tests will open an input field for the query. Upon hitting Enter, the test will run.
To make text input easier, you can also use the ADB command:
adb shell input text [query]
Note that '%s' will add a space between words. For example, the command adb shell input text hello%sworld will add the text "hello world" to the input field.
adb shell input text hello%sworld
The MCT currently includes simple single-media-action tests for the following requests:
For a technical deep dive on how the tests are structured and how to add more tests, visit the MCT GitHub Wiki. We'd love for you to submit pull requests with more tests that you think are useful to have and for any bug fixes. Please make sure to review the contributions process for more information.

Google Play Instant enables people to experience your game or app natively without having to go through a full installation process. Removing the friction of installing is a great way to increase engagement, conversions, and lifetime value of your users.
Today, we've made it easier to build instant games and apps by removing the URL requirement. Previously, in order to publish an instant game you had to create a web destination for it. The website also had to be connected to the instant game through intent filters and digital asset links verification.
Now, it is no longer required to add URL-based intent filters to your instant game. People will be able to access the instant experience through a 'Try Now' button in the Play Store or Play Games apps, via deep link API, and in the future through the app ads.
While being particularly helpful for games which often don't have a corresponding website, the new URL-less functionality is available to both game and app developers.
Game developers using Unity or the latest Cocos Creator can take advantage of URL-less instant games by simply leaving the URL fields blank in the setup process.
However, if you have your own game engine or have built your game from scratch in C++, check the AndroidManifest to make sure it has the following intent filter declaration:
<intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter>
Starting with Android Studio 3.2, you can create a new instant game, or convert your existing game, without associating a URL with it. In fact, this is now the default behavior. Here is a run through the process:
You should see an instant game on your attached device. Instant runtime found and launched the entry point activity in your game with the ACTION_MAIN and CATEGORY_LAUNCHER intent filter.
Once you are ready to publish the sample instant game:
Once you publish your instant game, people can access it via a 'Try Now' button in Play Store within 24 hours or sooner. You can also send traffic to your instant game using the deep link API:
market://details?id=MY.PACKAGE.NAME&launch=true&referrer=myreferrer
MY.PACKAGE.NAME refers to applicationId that you have replaced in app/build.gradle file.
MY.PACKAGE.NAME
With the launch of Android App Bundle we are excited to further simplify the developer experience for Google Play Instant. In the coming months we are making it possible to deliver your app's or game's dynamic features instantly from the same bundle as your installable app or game. Stay tuned!

Last year we announced that starting from August 2018 Google Play will require all new apps and games to target a recent Android API level – set to API level 26 (Android 8.0 Oreo), or higher. Additionally, this requirement will extend to updates for existing apps and games starting from November 2018.
Every new Android version introduces changes that bring significant security and performance improvements – and enhance the user experience of Android overall. Updating your games to target the latest API level ensures that your users can benefit from these improvements, while still allowing your games to run on older Android versions.
Simple next steps:
Significant changes to be aware of:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Moving ahead
Remember, updating the target API level is just the first step – make sure your game is compatible with the behavior changes between your current target API level and API level 26. Check out further guidance on the changes in past versions of Android to help in your migration process. These policy changes are important for moving the Android ecosystem forward and keeping it healthy for our users – and yours.

Since the major revamp of the Android Emulator two years ago, we have focused on delivering a fast and feature-rich emulator to help you build great app experiences for users. Today, the Android Emulator is the top device deployed to from Android Studio — more than 2x over physical Android devices. We are humbled to hear from many of you that the Android Emulator has come a long way, but we are not done yet.
Making the Android Emulator faster is one of the top priorities for the Android Studio team. Over the last few releases, we have launched quick boot & emulator snapshots for quickly starting and resuming emulator sessions in under 2 seconds. Up until now, our emulator experience has almost universally worked on macOS® and Linux computers. But for users of Microsoft® Windows® or the Microsoft® Hyper-V™ platform, our hardware accelerated speed enhancements for the Android Emulator only worked with computers with Intel® processors. Support for AMD® processors and Microsoft Hyper-V hypervisor are two long-standing user requests from the Android developer community that we are happy to address with this Android Emulator update.
Today, you can download the latest Android Emulator release, which is enabled to run x86 based Android Virtual Devices (AVD) on computers that use AMD processors. This exciting update makes the Android Emulator more accessible to a new set of Android app developers that were previously limited to software emulation, but can now have hardware accelerated performance. Moreover, for those of you who use Hyper-V to run your local app backend, the Android Emulator can now also coexist with other Hyper-V-backed applications on Windows® 10.
Thanks to a new Microsoft Windows Hypervisor Platform (WHPX) API and recent open-source contributions from Microsoft, even more Android app developers can take advantage of all the speed improvements and features in the Android Emulator.
Android Emulator running on Windows 10 with AMD Processor Screenshot Configuration: Asus ROG Strix GL 702ZC, Processor: AMD® Ryzen™ 7 1700 Processor, Chipset: AMD 5350, Graphics: AMD® Radeon™ RX580
Support for these technologies was initially available in the v27.3.8 Android Emulator canary release and today we are releasing this set of preview features (AMD processor & Hyper-V support) on the stable channel for more feedback. Alongside this update, we have added additional speed improvements in loading emulator snapshots for those developers using the Intel® Hardware Accelerated Execution Manager (HAXM).
If you use Linux for Android app development, the Android Emulator will continue to use the native Kernel-based Virtual Machine (KVM) hypervisor for both Intel and AMD based computers for a fast and performant virtualization solution. An update to the v27.3.8 Android Emulator will offer you the new snapshots UI along with improvements to performance, reliability and resource usage.
For OS X v10.10 Yosemite and higher, the Android Emulator uses the built-in Hypervisor.Framework by default, and falls back to using the Intel Hardware Accelerated Execution Manager (HAXM) if Hypervisor.Framework fails to initialize (such as when running on OS X v10.9 or earlier). Once you update to the latest Android Emulator on macOS, you will also have access to the new snapshots UI along with under the hood performance and reliability improvements.
Android Emulator - Snapshots Extended Controls
On Intel x86-based computers, the Android Emulator will continue to use Intel HAXM by default. Intel HAXM is a mature and open-sourced hypervisor solution developed by Intel. Thanks to on-going development by Intel, the fastest emulator performance on Windows is still with Intel HAXM. To download the latest Intel HAXM v7.2.0, check for updates in the Android SDK Manager.
If you have an AMD processor in your computer you need the following setup requirements to be in place:
Windows Hypervisor Platform setting in Windows 10
If you want to use Hyper-V at the same time as the Android Emulator on your Intel processor-based computer, you will also need the same Android Studio and Android Emulator versions as listed above, but with the additional requirements:
For more setup tips and troubleshooting details, check out the documentation page.
Again, for existing Windows users who have an Intel-based processor, the Android Emulator will continue to use the faster and recommended Intel HAXM configuration. For those using AMD processors, and those who use Hyper-V hypervisors, this should be an exciting step forward to start using the Android Emulator.
Download the latest Android Emulator from the Android Studio 3.2 Beta SDK Manager for the latest performance updates across all supported platforms that you are using. We are going to continue to invest in performance improvements for each of the platforms and we look forward to your feedback and feature requests.
If you find a bug or issue, feel free to file an issue. Connect with us -- the Android Studio development team ‐ on our Google+ page or on Twitter.
Starting today, you can download Android Studio 3.2 Beta. Previewed at Google I/O 2018, the latest release of the official Android IDE is focused on helping onboard you to all the new features launched around Google I/O -- Android JetPack, Android P Developer Preview, and the new Android App Bundle format. There are also several other exciting new features included in Android Studio 3.2 to accelerate your app development, such as Emulator Snapshots and the Energy Profiler.
As the usage of Android Studio has grown in the 3.5 years since version 1.0, we have also become increasingly obsessed with quality. We continue to invest in quality because we know that millions of app developers spend almost everyday in Android Studio and need a reliable set of tools. Stability, build times, and other quality work will be the primary focus for our next release once we finish Android Studio 3.2. We also did not want to wait, so we have made checkins to address memory leaks and performance issues as well as fixed more than 450 bugs. Thank you for the continued feedback and please keep it coming so we can focus on the areas you care about most in the next version of Android Studio. If want to try out the latest features, and assess the improvements in quality, you can download Android Studio on the beta release channel.
