In a future version of Android Gradle plugin, the versionName and versionCode properties will also be removed from the DSL for libraries. You can set the path to your local NDK installation using the android.
If you use this property together with the android. We've changed the behavior of how library unit tests are compiled and run. This configuration typically results in better testing. In some cases library unit tests that use data binding may encounter missing DataBindingComponent or BR classes.
Those tests need to be ported to an instrumented test in the androidTest project, since compiling and running against those classes in a unit test may produce incorrect output. The io. Gradle 6. To learn more, read the section about updating Gradle. This minor update supports compatibility with new default settings and features for package visibility in Android In previous versions of Android, it was possible to view a list of all apps installed on a device.
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. With Gradle, you can easily manipulate the build process and its logic to create multiple versions of your app.
Download SocializifyStarter , the starter project for this tutorial. Pay attention to the files with the green Gradle icon and. These files are generated by Android Studio automatically during project creation. Find the build. It contains the settings which are applied to all modules of the project. Now go to the build. It contains dependencies libraries which a module relies on , and instructions for the build process. Each module defines its own build.
Whew, build. Its contents should look as follows:. Here we have only one module — app. In a large, multi-module project, this file can have a much longer list. Besides Android apps, you can also write back-end web code, front-end web code, and even iOS apps using Kotlin! Recently, Gradle announced Kotlin language support for writing build scripts.
First of all, Kotlin is a statically typed language Groovy is dynamically typed , which allows for conveniences like autocompletion , better refactoring tools and source-code navigation.
Moreover, autocompletion will prevent you from making typos :]. To execute Gradle commands, you can use both the command line and Android Studio. So, how can you start working with Gradle commands? Pretty easy — use gradlew. These commands exist to help you with tasks like project initialization, building, testing and analyzing.
If you forget a specific command, just execute. Run the first command:. Verify this by changing to the build output directory:. The ls command displays all files and directories in the current directory. The -R parameter forces this command to execute recursively. The first command will find all the issues in a project with both critical and minor severity.
You can inspect all the issues found with code snippets and an expanded description of a possible solution. To get started with Picasso, you need to add it as a dependency to your project.
First, create a file named dependencies. Then it will run your Emulator, and your run button will become green again and you can use it.
