This means that you can now include standard language APIs that were available only in recent Android releases such as java. Note that you may also need to include the above code snippet in a library module 's build.

The library module's instrumented tests use these language APIs either directly or through the library module or its dependencies. You want to run lint on the library module in isolation. This is to help lint recognize valid usages of the language APIs and avoid reporting false warnings.

In previous versions of the Android Gradle plugin, all feature modules could depend only on the app's base module. When using Android Gradle plugin 4. That is, a :video feature can depend on the :camera feature, which depends on the base module, as shown in the figure below.

Feature module :video depends on feature :camera , which depends on the base :app module. This means that when your app requests to download a feature module, the app also downloads other feature modules it depends on. For example, the :video module declares a dependency on :camera as follows:. When building your app using Android Gradle plugin 4. When uploading your app, the Play Console inspects this metadata to provide you with the following benefits:.

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. Learn how to development project in real world.

To simplify this work for you, we've built the Downloader Library , which requests the expansion file URLs through the licensing service, downloads the expansion files, performs all of the tasks listed above, and even allows your activity to pause and resume the download.

By adding the Downloader Library and a few code hooks to your app, almost all the work to download the expansion files is already coded for you.

As such, in order to provide the best user experience with minimal effort on your behalf, we recommend you use the Downloader Library to download your expansion files. The information in the following sections explain how to integrate the library into your app. If you'd rather develop your own solution to download the expansion files using the Google Play URLs, you must follow the app Licensing documentation to perform a license request, then retrieve the expansion file names, sizes, and URLs from the response extras.

To use APK expansion files with your app and provide the best user experience with minimal effort on your behalf, we recommend you use the Downloader Library that's included in the Google Play APK Expansion Library package. This library downloads your expansion files in a background service, shows a user notification with the download status, handles network connectivity loss, resumes the download when possible, and more.

To use the Downloader Library, you need to download two packages from the SDK Manager and add the appropriate libraries to your app. For each library:. With both the License Verification Library and Downloader Library added to your app, you'll be able to quickly integrate the ability to download expansion files from Google Play.

The format that you choose for the expansion files and how you read them from the shared storage is a separate implementation that you should consider based on your app needs. Tip: The Apk Expansion package includes a sample app that shows how to use the Downloader Library in an app. In order to download the expansion files, the Downloader Library requires several permissions that you must declare in your app's manifest file. They are:.

In order to perform downloads in the background, the Downloader Library provides its own Service subclass called DownloaderService that you should extend. In addition to downloading the expansion files for you, the DownloaderService also:. All you need to do is create a class in your app that extends the DownloaderService class and override three methods to provide specific app details:. For example, here's a complete implementation of DownloaderService :.

You can find the key in the Developer Console under your profile information. This is necessary even when testing your downloads. You must define the BroadcastReceiver to call an API from the Downloader Library that checks the status of the download and restarts it if necessary. You simply need to override the onReceive method to call DownloaderClientMarshaller.

Notice that this is the class for which you must return the name in your service's getAlarmReceiverClassName method see the previous section. The main activity in your app the one started by your launcher icon is responsible for verifying whether the expansion files are already on the device and initiating the download if they are not. For example, the sample app provided in the Apk Expansion package calls the following method in the activity's onCreate method to check whether the expansion files already exist on the device:.

In this case, each XAPKFile object holds the version number and file size of a known expansion file and a boolean as to whether it's the main expansion file. See the sample app's SampleDownloaderActivity class for details. The method returns an integer that indicates whether or not the download is required.

Possible values are:. In order to instantiate your IStub by calling CreateStub , you must pass it an implementation of the IDownloaderClient interface and your DownloaderService implementation. The next section about Receiving download progress discusses the IDownloaderClient interface, which you should usually implement in your Activity class so you can update the activity UI when the download state changes.

For example, in the previous code sample for onCreate , you can respond to the startDownloadServiceIfRequired result like this:. After the onCreate method returns, your activity receives a call to onResume , which is where you should then call connect on the IStub , passing it your app's Context.

Conversely, you should call disconnect in your activity's onStop callback. Calling connect on the IStub binds your activity to the DownloaderService such that your activity receives callbacks regarding changes to the download state through the IDownloaderClient interface. To receive updates regarding the download progress and to interact with the DownloaderService , you must implement the Downloader Library's IDownloaderClient interface.

Usually, the activity you use to start the download should implement this interface in order to display the download progress and send requests to the service. With the IDownloaderService object initialized, you can send commands to the downloader service, such as to pause and resume the download requestPauseDownload and requestContinueDownload. To provide a useful message to your users, you can request a corresponding string for each state by calling Helpers.

This returns the resource ID for one of the strings bundled with the Downloader Library. Tip: For examples of these callbacks that update the download progress UI, see the SampleDownloaderActivity in the sample app provided with the Apk Expansion package. Some public methods for the IDownloaderService interface you might find useful are:.

Note: If you do use the Downloader Library as discussed in the previous section, the library performs all interaction with the APKExpansionPolicy so you don't have to use this class directly. The class includes methods to help you get the necessary information about the available expansion files:. For more information about how to use the APKExpansionPolicy when you're not using the Downloader Library , see the documentation for Adding Licensing to Your App , which explains how to implement a license policy such as this one.

Once your APK expansion files are saved on the device, how you read your files depends on the type of file you've used. Regardless of how you read your files, you should always first check that the external storage is available for reading. There's a chance that the user has the storage mounted to a computer over USB or has actually removed the SD card. Note: When your app starts, you should always check whether the external storage space is available and readable by calling getExternalStorageState.

This returns one of several possible strings that represent the state of the external storage. As described in the overview , your APK expansion files are saved using a specific file name format:.

To get the location and names of your expansion files, you should use the getExternalStorageDirectory and getPackageName methods to construct the path to your files. Here's a method you can use in your app to get an array containing the complete path to both your expansion files:.

You can call this method by passing it your app Context and the desired expansion file's version. There are many ways you could determine the expansion file version number.

One simple way is to save the version in a SharedPreferences file when the download begins, by querying the expansion file name with the APKExpansionPolicy class's getExpansionFileName int index method. You can then get the version code by reading the SharedPreferences file when you want to access the expansion file. For more information about reading from the shared storage, see the Data Storage documentation. This is an optional library that helps you read your expansion files when they're saved as ZIP files.

Using this library allows you to easily read resources from your ZIP expansion files as a virtual file system. If you're using your expansion files to store media files, a ZIP file still allows you to use Android media playback calls that provide offset and length controls such as MediaPlayer. For example, when using the zip tool, you should use the -n option to specify the file suffixes that should not be compressed:. The above code provides access to any file that exists in either your main expansion file or patch expansion file, by reading from a merged map of all the files from both files.

Context and the version number for both the main expansion file and patch expansion file. If you'd rather read from a specific expansion file, you can use the ZipResourceFile constructor with the path to the desired expansion file:. For more information about using this library for your expansion files, look at the sample app's SampleDownloaderActivity class, which includes additional code to verify the downloaded files using CRC.
