Android Gradle plugin 8.4 release notes

The JCenter repository became read-only on March 31st, 2021. For more information, see JCenter service update.

The Android Studio build system is based on Gradle, and the Android Gradle plugin adds several features that are specific to build Android apps. Although the Android Gradle plugin (AGP) is typically updated in lock-step with Android Studio, the plugin (and the rest of the Gradle system) can run independent of Android Studio and be updated separately.

This page explains how to keep your Gradle tools up to date and what's in the recent updates. For the release notes for past Android Gradle plugin versions, see past release notes.

To see what's been fixed in this version of the Android Gradle plugin, see the closed issues.

For a high-level summary of upcoming breaking changes in the Android Gradle plugin, see the Android Gradle plugin roadmap.

For details about how to configure your Android builds with Gradle, see the following pages:

For more information about the Gradle build system, see the Gradle user guide.

Update the Android Gradle plugin

When you update Android Studio, you may receive a prompt to automatically update the Android Gradle plugin to the latest available version. You can choose to accept the update or manually specify a version based on your project's build requirements.

You can specify the plugin version in either the File > Project Structure > Project menu in Android Studio, or the top-level build.gradle.kts file. The plugin version applies to all modules built in that Android Studio project. The following example sets the plugin to version 8.4.0 from the build.gradle.kts file:

Kotlin

plugins {
    id("com.android.application") version "8.4.0" apply false
    id("com.android.library") version "8.4.0" apply false
    id("org.jetbrains.kotlin.android") version "1.9.23" apply false
}

Groovy

plugins {
    id 'com.android.application' version '8.4.0' apply false
    id 'com.android.library' version '8.4.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.9.23' apply false
}

Caution: You should not use dynamic dependencies in version numbers, such as 'com.android.tools.build:gradle:8.4.+'. Using this feature can cause unexpected version updates and difficulty resolving version differences.

If the specified plugin version has not been downloaded, Gradle downloads it the next time you build your project or click File > Sync Project with Gradle Files from the Android Studio menu bar.

Update Gradle

When you update Android Studio, you may receive a prompt to also update Gradle to the latest available version. You can choose to accept the update or manually specify a version based on your project's build requirements.

The following table lists which version of Gradle is required for each version of the Android Gradle plugin. For the best performance, you should use the latest possible version of both Gradle and the plugin.

Plugin version	Minimum required Gradle version
8.4	8.6
8.3	8.4
8.2	8.2
8.1	8.0
8.0	8.0
7.4	7.5

Older versions

Plugin version	Required Gradle version
7.3	7.4
7.2	7.3.3
7.1	7.2
7.0	7.0
4.2.0+	6.7.1
4.1.0+	6.5+
4.0.0+	6.1.1+
3.6.0 - 3.6.4	5.6.4+
3.5.0 - 3.5.4	5.4.1+
3.4.0 - 3.4.3	5.1.1+
3.3.0 - 3.3.3	4.10.1+
3.2.0 - 3.2.1	4.6+
3.1.0+	4.4+
3.0.0+	4.1+
2.3.0+	3.3+
2.1.3 - 2.2.3	2.14.1 - 3.5
2.0.0 - 2.1.2	2.10 - 2.13
1.5.0	2.2.1 - 2.13
1.2.0 - 1.3.1	2.2.1 - 2.9
1.0.0 - 1.1.3	2.2.1 - 2.3

You can specify the Gradle version in either the File > Project Structure > Project menu in Android Studio, or update your Gradle version using the command line. The preferred way is to use the Gradle Wrapper command line tool, which updates the gradlew scripts. The following example sets the Gradle version to 8.4 using the Gradle Wrapper. Note, you need to run this command twice to upgrade both Gradle and the Gradle Wrapper itself (for more information, see Upgrading the Gradle Wrapper).

gradle wrapper --gradle-version 8.4

However this might fail in some cases, for example if you've just updated AGP and it's no longer compliant with the current Gradle version. In this case, you need to edit the Gradle distribution reference in the gradle/wrapper/gradle-wrapper.properties file. The following example sets the Gradle version to 8.4 in the gradle-wrapper.properties file.

...
distributionUrl = https\://services.gradle.org/distributions/gradle-8.4-bin.zip

Android Gradle plugin and Android Studio compatibility

The Android Studio build system is based on Gradle, and the Android Gradle plugin (AGP) adds several features that are specific to building Android apps. The following table lists which version of AGP is required for each version of Android Studio.

Koala \| 2024.1.1	3.2-8.5
Jellyfish \| 2023.3.1	3.2-8.4
Iguana \| 2023.2.1	3.2-8.3

Flamingo \| 2022.2.1	3.2-8.0

Older versions

Android Studio version	Required AGP version
Electric Eel \| 2022.1.1	3.2-7.4

Minimum versions of tools for Android API level

There are minimum versions of Android Studio and AGP that support a specific API level. Using lower versions of Android Studio or AGP than required by your project's targetSdk or compileSdk could lead to unexpected issues. We recommend using the latest preview version of Android Studio and AGP to work on projects that target preview versions of the Android OS. You can install preview versions of Android Studio alongside a stable version.

The minimum versions of Android Studio and AGP are as follows:

API level	Minimum Android Studio version	Minimum AGP version
VanillaIceCream preview	Jellyfish \| 2023.3.1	8.4
34	Hedgehog \| 2023.1.1	8.1.1
33	Flamingo \| 2022.2.1	7.2

Versioning changes (November 2020)

We are updating the version numbering for Android Gradle plugin (AGP) to more closely match the underlying Gradle build tool.

Here are the notable changes:

AGP will now use semantic versioning, and breaking changes will be targeted for major releases.
There will be one major version of AGP released per year, aligned with the Gradle major release.
The release after AGP 4.2 will be version 7.0 and will require an upgrade to Gradle version 7.x. Every major release of AGP will require a major version upgrade in the underlying Gradle tool.
APIs will be deprecated approximately one year in advance, with replacement functionality made available concurrently. Deprecated APIs will be removed approximately one year later during the subsequent major update.

Compatibility

The maximum API level that Android Gradle plugin 8.3 supports is API level 34. Here is other compatibility info:

	Minimum version	Default version	Notes
Gradle	8.6	8.6	To learn more, see updating Gradle.
SDK Build Tools	34.0.0	34.0.0	Install or configure SDK Build Tools.
NDK	N/A	26.1.10909125	Install or configure a different version of the NDK.
JDK	17	17	To learn more, see setting the JDK version.

The following are new features in Android Gradle plugin 8.4.

Library classes are shrunk

Starting with Android Gradle Plugin 8.4, if an Android library project is minified, shrunk program classes will be published for inter-project publishing. This means that if an app depends on the shrunk version of the Android library subprojects, the APK will include shrunk Android library classes. You may need to adjust library keep rules in case there are missing classes in the APK.

In case you are building and publishing an AAR, local jars that your library depends on will be included unshrunk in the AAR, which means code shrinker won't run on them.

To revert to previous behavior, set android.disableMinifyLocalDependenciesForLibraries in the gradle.properties file and file a bug. Future versions of AGP will remove this flag remove this flag.
