Incremental annotation processing
The Data Binding
annotation processor supports
incremental annotation processing
if you set
android.databinding.incremental=true in your
gradle.properties file. This optimization results in improved
incremental build performance. For a full list of optimized annotation
processors, refer to the table of incremental annotation
Additionally, KAPT 1.3.30 and higher also support incremental annotation
processors, which you can enable by including
Cacheable unit tests
When you enable unit tests to use Android resources, assets, and
manifests by setting
true, the Android Gradle plugin generates a test config file
containing absolute paths, which breaks cache relocatability. You can instruct
the plugin to instead generate the test config using relative paths, which
AndroidUnitTest task to be fully cacheable, by
including the following in your
android.testConfig.useRelativePath = true
When using Kotlin Gradle plugin 1.3.31 or earlier, you might see the following warning when building or syncing your project:
WARNING: API 'variant.getPackageLibrary()' is obsolete and has been replaced with 'variant.getPackageLibraryProvider()'.
To resolve this issue, upgrade the plugin to version 1.3.40 or higher.
