Android Gradle Plugin 7.2.0 (May 2022)

Android Gradle plugin 7.2.0 is a major release that includes a variety of new features and improvements.

Compatibility

Jetifier warning and check in Build Analyzer

Build Analyzer now displays a warning if your project's gradle.properties file includes android.enableJetifier=true. This flag was introduced in a previous version of Android Studio to enable AndroidX for libraries that don't support AndroidX natively. However, the library ecosystem has mostly moved to support AndroidX natively and the Jetifier flag is probably no longer needed by your project. Additionally, the flag can lead to slower build performance. If you see this warning, you can run a check within Build Analyzer to confirm if the flag can be removed.

Support for test fixtures

Starting with Android Studio Chipmunk Beta 1, Android Studio supports both Android and Java test fixtures. See Gradle's guide on using test fixtures{:.external} for more information on the test fixtures feature and how to use it in a Java project.

To enable test fixtures in your Android library module, add the following to your library-level build.gradle file:

android {
  testFixtures {
    enable true
    // enable testFixtures's android resources (disabled by default)
    // androidResources true
  }
}

By default, publishing your library also publishes the test fixtures AAR with the main library. The Gradle Module Metadata file will contain information for Gradle to be able to consume the right artifact when requesting the testFixtures component.

To disable publishing the test fixtures AAR of a library in the release variant, add the following to your library-level build.gradle file:

afterEvaluate {
  components.release.withVariantsFromConfiguration(
    configurations.releaseTestFixturesVariantReleaseApiPublication) { skip() }
  components.release.withVariantsFromConfiguration(
    configurations.releaseTestFixturesVariantReleaseRuntimePublication) { skip() }
}

To consume the test fixtures AAR of a published Android library, you can use Gradle's helper method testFixtures().

dependencies {
  testImplementation testFixtures('com.example.company:publishedLib:1.0')
}

By default, lint will analyze test fixtures sources. You can configure lint to ignore test fixtures sources as follows:

android {
  lint {
    ignoreTestFixturesSources true
  }
}

Duplicate content roots not supported

Starting with AGP 7.2, you can no longer share the same source directory across multiple source sets. For example, you can't use the same test sources for both unit tests and instrumentation tests. To learn more, see Change the default source sets configurations.
