Android studio gradle download

Starting with Android 11 API level 30 , by default apps have access to only a filtered list of installed packages. For more information on this new feature, see Package visibility in Android The Build Analyzer window helps you understand and diagnose issues with your build process, such as disabled optimizations and improperly configured tasks.

This feature is available when you use Android Studio 4. You can open the Build Analyzer window from Android Studio as follows:. The Build Analyzer window organizes possible build issues in a tree on the left.

You can inspect and click on each issue to investigate its details in the panel on the right. When Android Studio analyzes your build, it computes the set of tasks that determined the build's duration and provides a visualization to help you understand the impact of each of these tasks.

You can also get details on warnings by expanding the Warnings node. In Android Studio 4. This means that you can now include standard language APIs that were available only in recent Android releases such as java. The desugaring process rewrites your app's code to instead use this library at runtime. To enable support for these language APIs, include the following in your app module 's build.

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. When new features are added, they will be disabled, by default.

You can then use the buildFeatures block to enable only the features you want, and it helps you optimize the build performance for your project. You can set the options for each module in the module-level build. Keep in mind, you can still use the buildFeatures block in the module-level build. 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 you follow the configuration steps described below, Gradle automatically makes these native libraries available to use with your external native build system, such as CMake. Note that Gradle only makes these libraries available to your build; you must still configure your build scripts to use them.

Libraries are exported using the Prefab package format. Each dependency can expose at most one Prefab package, which comprises one or more modules.

A Prefab module is a single library, which could be either a shared, static, or header-only library. Typically, the package name matches the Maven artifact name and the module name matches the library name, but this is not always true. Because you need to know the package and module name of the libraries, you might need to consult the dependency's documentation to determine what those names are. CMake ndk-build.

This value will be set automatically by Gradle when CMake is invoked, so if your build system modifies this variable, be sure to append rather than assign to it. This command searches for config-file packages that match the given package name and version and exposes the targets it defines to be used in your build.

For example, if your application defines libapp. When you build your project, your external native build system automatically links libapp. For additional information, refer to the curl prefab sample. The behavior for app signing configurations in the signingConfig block has changed to the following:.

These changes allow AGP to optimize builds by disabling the signing mechanism based on whether the user has explicitly enabled these flags. Prior to this release, it was possible for v1Signing to be disabled even when explicitly enabled, which could be confusing. Android Gradle plugin 3. In Android Gradle plugin 4. So, to use the latest Android Gradle plugin, you need to migrate your instant app to support Android App Bundles. By migrating your instant apps, you can leverage the benefits of app bundles and simplify your app's modular design.

The ability to separate annotation processing into a dedicated task has been removed. This option was used to maintain incremental Java compilation when non-incremental annotation processors are used in Java-only projects; it was enabled by setting android.

Instead, you should migrate to using incremental annotation processors to improve build performance. The Android Gradle plugin no longer checks for or includes annotation processors you declare on the compile classpath, and the annotationProcessorOptions. If you include annotation processors on the compile classpath, you might get the following error:.

To resolve this issue, you must include annotation processors in your build. To learn more, read Add annotation processors. Prior versions of the Android Gradle Plugin required that you explicitly package any prebuilt libraries used by your CMake external native build by using jniLibs. With Android Gradle Plugin 4. External native build now automatically packages those libraries, so explicitly packaging the library with jniLibs results in a duplicate.

To avoid the build error, move the prebuilt library to a location outside jniLibs or remove the jniLibs configuration from your build. Changes in Android Gradle plugin 4. Gradle 5. View binding provides compile-time safety when referencing views in your code. You can now replace findViewById with the auto-generated binding class reference. To start using View binding, include the following in each module's build. The Android Gradle plugin includes support for the Maven Publish Gradle plugin , which allows you to publish build artifacts to an Apache Maven repository.

The Android Gradle plugin creates a component for each build variant artifact in your app or library module that you can use to customize a publication to a Maven repository. To learn more, go to the page about how to use the Maven Publish plugin. When building the debug version of your app, the plugin uses a new packaging tool, called zipflinger , to build your APK.

This new tool should provide build speed improvements. If the new packaging tool doesn't work as you expect, please report a bug.

You can revert to using the old packaging tool by including the following in your gradle. Gradle can output a Chrome trace that contains timestamps for these compiler events so you can better understand the time required to build your project. To output this build attribution file, do the following:. Add the flag -Pandroid. The file is named profile- timestamp.

When you build your app, the plugin now sets extractNativeLibs to "false" by default. That is, your native libraries are page aligned and packaged uncompressed. While this results in a larger upload size, your users benefit from the following:.

If you want the Android Gradle plugin to instead package compressed native libraries, include the following in your app's manifest:.

If you download multiple versions of the NDK, the Android Gradle plugin now selects a default version to use in compiling your source code files.

Previously, the plugin selected the latest downloaded version of the NDK. Use the android. The Android Gradle plugin simplifies the compile classpath by generating only one R class for each library module in your project and sharing those R classes with other module dependencies. This optimization should result in faster builds, but it requires that you keep the following in mind:. This behavior change should result in fewer Resource Not Found runtime exceptions and improved build speed. When compiling your app, D8 now respects when annotations apply a CLASS retention policy, and those annotations are no longer available at runtime.

Command-line completion scripts are available for bash and zsh. This provides completion for Gradle tasks and command-line options. If you downloaded a. That's it. The following video shows each step of the setup procedure when using the recommended. This prompt is caused by new privacy protection mechanisms for applications that access files under the home directory.

So, if your project includes files and libraries in your home directory, and you see this prompt, you can select Don't Allow.

If you're using a bit version of Linux, make sure you first install the required libraries for bit machines. If you are running a bit version of Ubuntu, you need to install some bitlibraries with the following command:. The Android Studio Setup Wizard guides you through the rest of thesetup, which includes downloading Android SDK components that arerequired for development.
