sample-library-react-native

This is a simple React Native project that demonstrates an issue with building Android libraries on React Native 0.57.5.

Issue

Any Android React Native project which uses apply plugin: "com.android.library" currently fails to build. The problem is that a recent change to react.gradle now uses android.applicationVariants when configuring the project. This is not present for library projects, so it fails.

Usage

1. Clone this repository
2. Run yarn install
3. Run cd android && ./gradlew build

You will see this error similar to this:

FAILURE: Build failed with an exception.

* Where:
Script '/Users/james/src/SampleLibrary/node_modules/react-native/react.gradle' line: 15

* What went wrong:
A problem occurred configuring project ':app'.
> Could not get unknown property 'applicationVariants' for object of type com.android.build.gradle.LibraryExtension.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
