The data is compressed, encrypted by a Google Play signing key, and stored in the signing block of your release app. When used with Android Studio, certain IDE features, such as the Project Structure dialog and build script quick fixes, now also support reading and writing to Kotlin build script files. Based on your feedback, we've focused our efforts on improving the user experience in the CPU Profiler in two important ways. Some notable UI changes include the following:. This version of Android Studio includes updates to the design tools, such as the Layout Inspector and an all-new Motion Editor.
Android Studio now includes a visual design editor for the MotionLayout layout type, making it easier to create and preview animations.
The Motion Editor provides a simple interface for manipulating elements from the MotionLayout library that serves as the foundation for animation in Android apps. In previous releases, creating and altering these elements required manually editing constraints in XML resource files.
Now, the Motion Editor can generate this XML for you, with support for start and end states, keyframes, transitions, and timelines. To learn more about how to use the Motion Editor, see the user guide. Along with many of the same features of the existing Layout Inspector, the Live Layout Inspector also includes:. You can use the Live Layout Inspector only when deploying your app to a device or emulator running API level 29 or higher.
Then click the checkbox next to Live updates above the Layout Display. Layout Validation is a visual tool for simultaneously previewing layouts on different devices and configurations, helping you detect layout errors and create more accessible apps. You can access this feature by clicking on the Layout Validation tab in the top-right corner of the IDE window:. In the Layout Validation window, you can select from four different configuration sets, including:.
Android Studio now provides smart editor features when you open code shrinker rules files for R8, such as syntax highlighting, code completion, and error checking. The editor also integrates with your Android Studio project to provide full symbol completion for all classes, methods, and fields, and includes quick navigation and refactoring.
Android Studio now includes Android live templates for your Kotlin classes. For example, you can now type toast and press the Tab key to quickly insert a Toast. To learn more about developing for Android 11, see the Android 11 documentation. The value for ndk. To learn more about the improvements from other IntelliJ versions that are included cumulatively with version We'd also like to thank all of our community contributors who have helped with this release.
This version of Android Studio includes updates to several design tools, including the Layout Editor and Resource Manager. Design editors, such as the Layout Editor and Navigation Editor, now provide a Split view that enables you to see both the Design and Code views of your UI at the same time. In the top-right corner of the editor window, there are now three buttons for toggling between viewing options:.
The controls for zooming and panning within design editors have moved to a floating panel in the bottom-right corner of the editor window. To help you quickly update color resource values in your app when you're using the color picker in your XML or the design tools, the IDE now populates color resource values for you.
The latest version of the Android Gradle plugin includes many updates, including optimizations for build speed, support for the Maven publishing plugin, and support for View Binding.
To learn more, read the full release notes. View binding allows you to more easily write code that interacts with views by generating a binding class for each XML layout file. These classes contain direct references to all views that have an ID in the corresponding layout.
Because it replaces findViewById , view binding eliminates the risk of null pointer exceptions resulting from an invalid view ID. To enable view binding, you need to use Android Gradle plugin 3.
You can now add a class and then deploy that code change to your running app by clicking either Apply Code Changes or Apply Changes and Restart Activity. You can now instant-enable your base module at any time after creating your app project as follows:. To learn more, read Overview of Google Play Instant. Automatically create a stub implementation function for a JNI declaration.
Unused native implementation functions are highlighted as a warning in the source code. JNI declarations with missing implementations are also highlighted as an error. When you rename refactor a native implementation function, all corresponding JNI declarations are updated. Rename a JNI declaration to update the native implementation function.
The code editor in Android Studio now supports a more seamless JNI development workflow, including improved type hints, auto-completion, inspections, and code refactoring. Android Studio detects changes in the APK and gives you the option to re-import it. When analyzing a heap dump in the Memory Profiler, you can now filter profiling data that Android Studio thinks might indicate memory leaks for Activity and Fragment instances in your app.
To use this feature, first capture a heap dump or import a heap dump file into Android Studio. Filtering a heap dump for memory leaks. Android Studio 3. Android Emulator When you open the Emulators Extended controls , options in the Location tab are now organized under two tabs: Single points and Routes.
In the Single points tab, you can use the Google Maps webview to search for points of interest, just as you would when using Google Maps on a phone or browser. When you search for or click on a location in the map, you can save the location by selecting Save point near the bottom of the map. All of your saved locations are listed on the right side of the Extended controls window. To set the Emulators location to the location you have selected on the map, click the Set location button near the bottom right of the Extended controls window.
Similar to the Single points tab, the Routes tab provides a Google Maps webview that you can use to create a route between two or more locations. To create and save a route, do the following:.
To simulate the Emulator following the route you saved, select the route from the list of Saved routes and click Play route near the bottom right of the Extended controls window. To stop the simulation, click Stop route. To continuously simulate the Emulator following the specified route, enable the switch next to Repeat playback.
To change how quickly the Emulator follows the specified route, select an option from the Playback speed dropdown. The Android Emulator now allows you to deploy your app to multiple displays, which support customizable dimensions and can help you test apps that support multi-window and multi-display. While a virtual device is running, you can add up to two additional displays as follows:.
Click Apply changes to add the specified display s to the running virtual device. When you create a new project using Android Studio, you can now select from three templates from the Automotive tab in the Create New Project wizard: No Activity , Media service , and Messaging service.
The Create New Module wizard then guides you through creating a new module using one of the Android Automotive project templates. When downloading SDK components and tools using the SDK Manager, Android Studio now allows you to resume downloads that were interrupted for example, due to a network issue instead of restarting the download from the beginning.
This enhancement is especially helpful for large downloads, such as the Android Emulator or system images, when internet connectivity is unreliable. In addition, if you have an SDK download task running in the background, you can now pause or resume the download using the controls in the status bar. A background download task in the status bar with new controls that let you pause or resume the download. The Windows bit version of Android Studio will no longer receive updates after December , and it will no longer receive support after December You can continue to use Android Studio.
However, to receive additional updates, upgrade your workstation to a bit version of Windows. To learn more, read the Windows bit depreciation blog. For large projects, retrieving the task list could cause slow sync times. When you enable this option, Android Studio skips building the task list during sync, which allows Gradle Sync to complete faster and improves UI responsiveness.
Keep in mind, when the IDE skips building the task list, the task lists in the Gradle panel are empty, and task name auto-completion in build files does not work. Then, near the top of the Gradle window, click Toggle Offline Mode. Thank you to all of our community contributors who have helped us discover bugs and other ways to improve Android Studio 3.
In particular, we'd like to thank the following people who reported bugs:. Beginning with the release of Android Studio 3. For information about these and other Project Marble updates, read the Android Developers blog post or the sections below. We also want to thank all of our community contributors who have helped with this release. This minor update includes various bug fixes and performance improvements.
This section describes the changes in Android Studio 3. Android Studio now notifies you if it detects that you could improve performance by increasing the maximum amount of RAM that your OS should allocate for Android Studio processes, such as the core IDE, Gradle daemon, and Kotlin daemon.
To learn more, see Maximum heap size. A notification about recommended memory settings. Memory problems in Android Studio are sometimes difficult to reproduce and report. When you do so, the IDE locally sanitizes the data for personal information before asking whether you want to send it to the Android Studio team to help identify the source of the memory issues.
To learn more, see Run a memory usage report. A memory usage report. Android Studio now automatically checks whether certain project directories are excluded from real-time antivirus scanning. When adjustments can be made to improve build performance, Android Studio notifies you and provides instructions on how to optimize your antivirus configuration.
To learn more, see Minimize the impact of antivirus software on build speed. Apply Changes lets you push code and resource changes to your running app without restarting your app—and, in some cases, without restarting the current activity. Unlike Instant Run, which rewrote the bytecode of your APK, Apply Changes redefines classes on the fly by leveraging the runtime instrumentation supported in Android 8. The toolbar buttons for Apply Changes. The IDE has a new drop-down menu that lets you quickly select which device you'd like to deploy your app to.
This menu also includes a new option that lets you run your app on multiple devices at once. Target device drop-down menu. The IDE now better detects when Gradle periodically clears your build cache when reducing its hard disk consumption.
In previous versions, this state caused the IDE to report missing dependencies and Gradle sync to fail. Now, the IDE simply downloads dependencies as needed to ensure that Gradle sync completes successfully. The Build window now provides better error reporting, such as a link to the file and line of the reported error, for the following build processes:. Improved update experience to provide more information and actions to help you update the IDE and the Android Gradle plugin.
For example, more sync and build errors include actions to help you mitigate errors when updating. So, you can safely update the IDE as soon as a newer version is available, and update other components later.
When working with ConstraintLayout , a new Constraints section in the Attributes panel lists the constraints relationships of the selected UI component. You can select a constraint either from the design surface or from the constraints list to highlight the constraint in both areas.
Constraint relationships for a selected UI element. Similarly, you can now delete a constraint by selecting it and pressing the Delete key.
You can also delete a constraint by holding the Control key Command on macOS and clicking on the constraint anchor. Note that when you hold the Control or Command key and hover over an anchor, any associated constraints turn red to indicate that you can click to delete them. When you create a new constraint, the Layout Editor now selects and highlights the constraint, providing immediate visual feedback for what you've just added. Using the constraint widget to create constraints.
When creating a constraint, the Layout Editor now shows only the eligible anchor points to which you can constrain. Previously, the Layout Editor highlighted all anchor points on all views, regardless of whether you could constrain to them.
In addition, a blue overlay now highlights the target of the constraint. This highlighting is particularly useful when attempting to constrain to a component that overlaps with another. Creating a constraint for an overlapping component in Android Studio 3.
In addition to the above updates, Android Studio 3. In addition to adding incremental annotation processing support for Data Binding, the IDE improves smart editor features and performance when creating data binding expressions in XML.
Code editor performance on Android Studio 3. This feature simplifies build configuration per module and can also improve Gradle sync performance. You can now use multiple versions of the NDK side-by-side. This feature gives you more flexibility when configuring your projects—for example, if you have projects that use different versions of the NDK on the same machine.
If your project uses Android Gradle plugin 3. You can use this feature to create reproducible builds and to mitigate incompatibilities between NDK versions and the Android Gradle plugin. To get started, download Android Studio on your compatible Chrome OS device and follow the installation instructions. Conditional delivery allows you to set certain device configuration requirements for feature modules to be downloaded automatically during app install. For example, you can configure a feature module that includes functionality for augmented reality AR to be available at app install for only devices that support AR.
This delivery mechanism currently supports controlling the download of a module at app install-time based on the following device configurations:. If a device does not meet all the requirements you specify, the module is not downloaded at app install-time. However, your app may later request to download the module on demand using the Play Core Library. To learn more, read Configure conditional delivery. The last IntelliJ version that was included with Android Studio was For more information about the improvements from other IntelliJ versions that are included cumulatively with this release of Android Studio, see the following bug-fix updates:.
In particular, we'd like to thank the following people who reported P0 and P1 bugs:. The new Project Structure Dialog PSD makes it easier to update dependencies and configure different aspects of your project, such as modules, build variants, signing configurations, and build variables. You can find descriptions of some of the new and updated sections of the PSD below. The new variables section of the PSD allows you to create and manage build variables, such as those to keep version numbers for dependencies consistent across your project.
Configure properties that are applied to all build variants in an existing module or add new modules to your project from the Modules section.
For example, this is where you can configure defaultConfig properties or manage signing configurations. Inspect and visualize each dependency in the dependency graph of your project, as resolved by Gradle during project sync, by following these steps:. Depending on the type of dependency you select, you should see a dialog, similar to the one below, that helps you add the dependency to the module.
In this section of the PSD, create and configure build variants and product flavors for each module in your project. You can add manifest placeholders, add ProGuard files, and assign signing keys, and more. See suggested updates for project dependencies and build variables in the Suggestions section, as shown below.
Resource Manager is a new tool window for importing, creating, managing, and using resources in your app. The Resource Manager allows you to do the following:. To learn more, read the guide about how to Manage app resources. When you provide debugging symbol files for the. If you build the native libraries in your APK with a build ID, Android Studio checks whether the build ID in your symbol files matches the build ID in your native libraries and rejects the symbol files if there is a mismatch.
If you did not build with a build ID, then providing incorrect symbol files may cause problems with debugging. R8 integrates desugaring, shrinking, obfuscating, optimizing, and dexing all in one step—resulting in noticeable build performance improvements.
R8 was introduced in Android Gradle plugin 3. Now, with R8, desugaring, shrinking, obfuscating, optimizing, and dexing D8 are all completed in one step, as illustrated below.
So, in this unlikely situation, you might need to add additional rules to keep that code in your build output. All argument types supported by the Navigation component are now supported in the Navigation Editor. For more information on supported types, see Pass data between destinations. The Attributes pane in the Layout Editor has been streamlined into a single page with sections you can expand to reveal attributes you can configure.
The Attributes pane also includes the following updates:. For example, if you reference the WorkManager class without first importing the required android. In particular, because Jetpack repackaged the support library into discrete packages that are easier to manage and update, this intention action helps you quickly add only the dependencies you need for the Jetpack components you want to use.
The Navigation Editor lets you quickly visualize and build navigation into your app by using the Navigation Architecture Component. For more information, see Implement navigation with the Navigation Architecture Component. The Delete Unused Android Studio Directories dialog then displays locations, sizes, and last-modified times of these unused directories and provides an option to delete them.
Lint, when invoked from Gradle, is significantly faster—larger projects can expect lint to run up to four times faster. The Create New Project wizard has a new look and contains updates that help streamline the creation of new Android Studio projects.
Based on user feedback, rendering performance while using the profilers has been greatly improved. Please continue to provide feedback , especially if you continue to see performance issues.
To improve app performance while profiling, the Memory Profiler now samples memory allocations periodically by default. If desired, you can change this behavior by using the Allocation Tracking dropdown when testing on devices running Android 8. Using the Allocation Tracking dropdown, you can choose from the following modes:. Off: turns memory allocation off. If not already selected, this mode is enabled automatically while taking a CPU recording and then returned to the previous setting when the recording is finished.
You can change this behavior in the CPU recording configuration dialog. This data might be useful when investigating bottlenecks that cause UI jank and low framerates. For example, each frame that takes longer than the 16ms required to maintain a smooth framerate is displayed in red.
To see frame rendering data, record a trace using a configuration that allows you to Trace System Calls. After recording the trace, look for info about each frame along the timeline for the recording under the section called FRAMES , as shown below.
To learn more about investigating and fixing framerate issues, read Slow rendering. The event timeline now shows when fragments are attached and detached. Additionally, when you hover over a fragment, a tooltip shows you the fragment status. Previously, the Network profiler displayed only raw text from connection payloads. In the Response and Request tabs, click the View Parsed link to display formatted text, and click the View Source link to display raw text.
For more information, see Inspect network traffic with Network Profiler. For more information, see Auto-download missing packages with Gradle. Android Studio now includes support for static code analysis using Clang-Tidy for projects that include native code.
When selecting this inspection in the Settings or Preferences dialog, you can also see the list of Clang-Tidy checks that are enabled and disabled under the Option section of the right-most panel. To enable additional checks , add them to the list and click Apply. CMake version 3. Note that Gradle still uses version 3. For more information on configuring CMake in build. In other words, you can now build and deploy both installed app and instant experiences from a single Android Studio project and include them in a single Android App Bundle.
Syncing your project with your build configuration is an important step in letting Android Studio understand how your project is structured. However, this process can be time-consuming for large projects. If your project uses multiple build variants, you can now optimize project syncs by limiting them to only the variant you have currently selected.
You need to use Android Studio 3. When you meet these requirements, the IDE prompts you to enable this optimization when you sync your project. The optimization is also enabled by default on new projects. For more information, see Enable single-variant project sync. If you've opted into sharing usage statistics to help improve Android Studio, you'll see these two new icons in the status bar at the bottom of the IDE window:. Simply click the icon that best represents your current experience with the IDE.
When you do so, the IDE sends usage statistics that allow the Android Studio team to better understand your sentiment. In some cases, such as when you indicate a negative experience with the IDE, you'll have an opportunity to provide additional feedback.
Kotlin version 1. Although you typically don't need to specify the build tools version, when using Android Gradle plugin 3. The assistant opens when you start Android Studio after a fresh installation or update if it detects that there is new information to show.
Android Jetpack helps to accelerate Android development with components, tools, and guidance that eliminate repetitive tasks and enable you to more quickly and easily build high-quality, testable apps. Android Studio includes the following updates to support Jetpack. For more information, see the Jetpack documentation. The new Navigation Editor integrates with the navigation components of Android Jetpack to provide a graphical view for creating the navigation structure of your app.
The Navigation Editor simplifies the design and implementation of navigation between in-app destinations. In Android Studio 3. To learn more, read the Navigation Editor documentation. As part of Jetpack, we are migrating the Android Support Libraries to a new Android extension library using the androidx namespace. For more information, see the AndroidX overview. If you have any Maven dependencies that have not migrated to the AndroidX namespace, the Android Studio build system also automatically converts those project dependencies.
The Android Gradle plugin provides the following global flags that you can set in your gradle. Both flags are set to true when you use the Migrate to AndroidX command. If you want to start using AndroidX libraries immediately and don't need to convert existing third-party libraries, you can set the android. You no longer need to build, sign, and manage multiple APKs, and users get smaller, more optimized downloads. Additionally, you can add feature modules to your app project and include them in your app bundle.
For more information, including instructions for building and analyzing an Android App Bundle, see Android App Bundle. Many Android layouts have runtime data that can make it difficult to visualize the look and feel of a layout during the design stage of app development. You can now easily see a preview of your view in the Layout Editor filled with sample data.
When you add a view, a button appears below the view in the Design window. Click this button to set the design-time view attributes. You can choose from a variety of sample data templates and specify the number of sample items with which to populate the view. To try using sample data, add a RecyclerView to a new layout, click the design-time attributes button below the view, and choose a selection from the carousel of sample data templates.
Slices provide a new way to embed portions of your app's functionality in other user interface surfaces on Android. For example, Slices make it possible to show app functionality and content in Google Search suggestions. Any advice would be appreciated?
