Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/32443 This diff removes all the custom Gradle machinery to build the native code and delegates to AGP the triggering of the `ndk-build` command. This means that the native build will be now invoked with the `:ReactAndroid:externalNativeBuild<Variant>` task. An important thing to notice is that that task will always run, and will delegate to Make the compilation avoidance. If you invoke the task twice, the second time it will be significantly faster. On my machine this takes ~6/7 mins the first time, and 30 seconds the second time. There are some gotchas that are worth noting: * The native build will run on every build now. Given the complexity of our native build graph, even with an up-to-date build, Make will still take ~30 seconds on my machine to analyse all the targets and mention that there is no work to be done. I believe this could be impactful for local development experience. The mitigation I found was to apply an `abiFilter` to build only the ABI of the target device (e.g. arm64 for a real device and so on). This reduces the native build to ~10 seconds. * All the change to the `react-native-gradle-plugin` source will cause the Gradle tasks to be considered invalid. Therefore they will re-extract the header files inside the folders that are used by Make to compile, triggering a near-full rebuild. This can be a bit painful when building locally, if you plan to edit react-native-gradle-plugin and relaunch rn-tester (seems to be like an edge case scenario but worth pointing out). The mitigation here would be to invoke the tasks like ``` gw :packages:rn-tester:android:app:installHermesDebug -x prepareBoost -x prepareLibevent -x prepareGlog \ -x prepareJSC -x extractNativeDependencies -x generateCodegenArtifactsFromSchema \ -x generateCodegenSchemaFromJavaScript ``` Changelog: [Internal] [Changed] - Refactor Extract Headers and JNI from AARs to an internal task Reviewed By: ShikaSD Differential Revision: D31683721 fbshipit-source-id: fa85793c567796f4e04751e10503717a88cb0620 |

React Native
Learn once, write anywhere:
Build mobile apps with React.
Getting Started · Learn the Basics · Showcase · Contribute · Community · Support
React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 11.0 and Android 5.0 (API 21) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in the React Native Community, @react-native-community/react-native-releases.
