butterknife v9.0.0 Release Notes

Release Date: 2019-01-03 // over 2 years ago
    • New: Support for AndroidX. Requires android.useAndroidX=true in gradle.properties to generate AndroidX code.

    • New: A butterknife-runtime artifact has been extracted from butterknife which contains the APIs required for the generated code but does not contain the code to reflectively look up the generated code. This allows you to reference the generated code directly such that R8/ProGuard optimization can rename both the generated code and your classes. ButterKnife.bind and the consumer R8/ProGuard rules remain in the old butterknife artifact.

    • New: Experimental butterknife-reflect artifact eliminates the need to run the annotation processor for IDE builds. This artifact is binary compatible with butterknife so it can be interchanged depending on how your build is being invoked. See [its README](butterknife-reflect/README.md) for more information. Currently about 90% of functionality is covered. File bugs for anything that does not work.

    Note: This artifact requires Java 8. There's no good reason for this except to push the ecosystem to having this be a default. As of AGP 3.2 there is no reason not to do this.

    • New: Lint checks have been ported to UAST and now work on Kotlin code.

    • Helpers such as apply have been deprecated on ButterKnife and are now available on the ViewCollections class.

    • Add support for Android Gradle plugin 3.3 and newer where R is no longer generated as Java source. This has a side-effect of removing support for Android Gradle plugin 3.0.x (and older).

    • Use Java 8 bytecode for all artifacts as announced in RC1 release notes.

    • Fix: Allow @BindFont to work prior to API 26 using ResourcesCompat.

    • Fix: Update Android Gradle plugin to 3.1 or newer to fix binary incompatibilities.

    • Fix: Correct generated resource annotation names when running Turkish locale.

    • Fix: Use the application ID instead of the resource package for generating R2.

    • Cache the fact that a class hierarchy has no remaining bindings to prevent traversing the hierarchy multiple times.

    • Deprecated methods from 8.x have been removed.
