Kotlin DSL is the default for build configuration
New projects now use the Kotlin DSL (build.gradle.kts
) by default for build
configuration. This offers a better editing experience than the Groovy DSL
(build.gradle
) with syntax highlighting, code completion, and navigation to
declarations. Note that if you're using AGP 8.1 and the Kotlin DSL for build
configuration, you should use Gradle 8.1 for the best experience. To learn more,
see the Kotlin DSL migration guide.
Automatic per-app language support
Starting with Android Studio Giraffe Canary 7 and AGP 8.1.0-alpha07, you can
configure your app to support per-app language
preferences automatically. Based on your
project resources, the Android Gradle plugin generates the LocaleConfig
file
and adds a reference to it in the final manifest file, so you no longer have to
do it manually. AGP uses the resources in the res
folders of your app modules
and any library module dependencies to determine the locales to include in the
LocaleConfig
file.
Note that the automatic per-app language feature supports apps that run Android
13 (API level 33) or higher. To use the feature, you must set
compileSdkVersion
to 33 or higher. To configure per-app language preferences
for prior versions of Android, you still need to
use the APIs and in-app language pickers.
To enable automatic per-app language support, specify a default locale:
- In the app module's
res
folder, create a new file calledresources.properties
. In the
resources.properties
file, set the default locale with theunqualifiedResLocale
label. To form the locale names, combine the language code with the optional script and region codes, separating each with a dash:- Language: Use the two- or three-letter ISO 639-1 code.
- Script (optional): Use the ISO 15924code.
- Region (optional): Use either the two-letter ISO 3166-1-alpha-2 code or three-digit UN_M.49 code.
For example if your default locale is American English:
unqualifiedResLocale=en-US
AGP adds this default locale and any
alternative locales
you've specified, using values-*
directories in the res
folder, to the
auto-generated LocaleConfig
file.
Automatic per-app language support is off by default. To turn the feature on,
use the generateLocaleConfig
setting in the androidResources {}
block of the
module-level build.gradle.kts
file (build.gradle
file if you're using
Groovy):
Kotlin
android { androidResources { generateLocaleConfig = true } }
Groovy
android { androidResources { generateLocaleConfig true } }
Android Lint contains bytecode targeting JVM 17
Starting with AGP 8.1.0-alpha04, Android Lint contains bytecode targeting JVM
17. If you write custom lint checks, you need to compile with JDK 17 or higher
and specify jvmTarget = '17'
in your Kotlin compiler options.
To learn more about the lint tool, see Improve your code with lint checks.
Native library compression setting moved to DSL
Starting with AGP 8.1.0-alpha10, you'll get a warning if you don't configure native library compression using the DSL instead of the manifest. The following guidance explains how to update your configuration to use the DSL. To get help making these updates, use the AGP Upgrade Assistant (Tools > AGP Upgrade Assistant).
To use uncompressed native libraries, remove the android::extractNativeLibs
attribute from the manifest and add the following code to the module-level
build.gradle.kts
file (build.gradle
file if you're using Groovy):
Kotlin
android { packagingOptions { jniLibs { useLegacyPackaging = false } } }
Groovy
android { packagingOptions { jniLibs { useLegacyPackaging false } } }
Experimental build flags
These are experimental flags for configuring your build available in AGP 8.1.
Flag | Added in | Default value | Notes |
---|---|---|---|
android.experimental.useDefaultDebugSigningConfigForProfileableBuildtypes |
AGP 8.0 | false |
Enabling this with no signing configs specified causes AGP to use the default debug signing config when running a profileable or debuggable build. This flag is disabled by default to encourage build authors to declare specific profiling signing configs. |
android.experimental.library.desugarAndroidTest |
AGP 8.0 | false |
This flag lets library builders enable core library desugaring for test APKs without affecting the AAR produced, for example through linting. We plan to eventually support this behavior in the Variant API. |
android.experimental.testOptions.managedDevices.customDevice |
AGP 8.0 | false |
If enabled, Gradle Managed Devices allows a user-defined custom device type that can be provided by a plugin. This flag must be enabled if you want to use the Firebase Test Lab plugin. |
android.lint.printStackTrace |
AGP 8.0 | false |
If enabled, Android lint prints a stacktrace if it crashes. This flag
has the same capabilities as the LINT_PRINT_STACKTRACE
environment variable. |
android.experimental.testOptions.managedDevices.maxConcurrentDevices |
AGP 8.0 | None | Specifies the maximum number of concurrent Gradle Managed Devices (AVDs) to be active at any one point in time. If the value is 0 or negative, there is no maximum number of devices. |
android.experimental.testOptions.installApkTimeout |
AGP 8.0 | None | The timeout duration in seconds to install an APK. If the value is 0 or negative, it will be set to a default value by UTP. |
