Summary: the current jsc-android is still built based on ndk r21, and react-native is now built based on ndk r23. the unwinder between r21 and r23 is incompatible (libgcc vs libunwind). if there's exceptions throwing from jsc, other react native libraries cannot catch these exceptions and cause runtime crash. this pr updates jsc-android to 235231.0.0 which is the same webkitgtk version as 235230.2.1 but only built by ndk r23. the jsc-android pr is from https://github.com/react-native-community/jsc-android-buildscripts/pull/179. note that the jsc is based on ndk r23c and react-native is based on ndk r23b. the reason is that i cannot get jsc building successfully on r23b. hopefully r23b and r23c are abi safe. there is another crash from libjscexecutor when testing the new jsc-android. to fix the issue, i have to explicitly link libunwind.a from libjscexecutor.so. supposedly ndk r23 should help to link libunwind under the hood, i still not figure out why it doesn't. but after linking libunwind.a, i can get new jsc-android work successfully. ``` E/art ( 2669): dlopen("/data/app/com.test-1/lib/x86_64/libjscexecutor.so", RTLD_LAZY) failed: dlopen failed: cannot locate symbol "_Unwind_Resume" referenced by "/data/app/com.test-1/lib/x86_64/libjscexecutor.so"...

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 12.4 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 this discussion repo.
