Summary: packagingOptions.pickFirst is unreliable that we could not specify which library will be used. If user have other third party libraries, the story is more complicated. From the framework point of view, it is better to drop the pickFirst. In jsc-android 241213.1.0, we did two things: 1. Remove libc++_shared.so in AAR to prevent the conflict with RN. 2. Build by NDK r17c, which aligned with current RN NDK version. In this commit, I also revert the pickFirst for JSC. pickFirst JSC also makes upgrade JSC unreliable. Currently a lot of user report JSC crash issues, those crash issues may relate to JIT and hard to reproduce in-house. My plan is to make sure user could choose another JSC build easier, i.e. only to `yarn add 'jsc-android@latest'`. We could then propose some experimented JSC build for user to check if the build could help them to fix the crash issue. [Android] [Fixed] - Remove unreliable packagingOptions.pickFirst for libc++_shared.so and libjsc.so NOTE that this may not need to add the changelog, as RN 0.59 does not have pickFirst. This will also reduce a breaking change for upgrade from RN 0.59 or before.

RNTester
The RNTester showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Both macOS and Xcode are required.
- Open
RNTester/RNTester.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on iOS with CocoaPods
Similar to above, you can build the app via Xcode with help of CocoaPods.
- Install CocoaPods
- Run
cd RNTester; pod install - Open the generated
RNTesterPods.xcworkspace(this is not checked in). Do not openRNTesterPods.xcodeprojdirectly.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :RNTester:android:app:installDebug
./scripts/packager.sh
Note: Building for the first time can take a while.
Open the RNTester app in your emulator.
See Running on Device in case you want to use a physical device.
Running with Buck
Follow the same setup as running with gradle.
Install Buck from here.
Run the following commands from the react-native folder:
./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch rntester
buck install -r rntester
./scripts/packager.sh
Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).
Running Detox Tests on iOS
Install Detox from here.
To run the e2e tests locally, run the following commands from the react-native folder:
yarn build-ios-e2e
yarn test-ios-e2e
These are the equivalent of running:
detox build -c ios.sim.release
detox test -c ios.sim.release --cleanup
These build the app in Release mode, so the production code is bundled and included in the built app.
When developing E2E tests, you may want to run in development mode, so that changes to the production code show up immediately. To do this, run:
detox build -c ios.sim.debug
detox test -c ios.sim.debug
You will also need to have Metro Bundler running in another terminal. Note that if you've previously run the E2E tests in release mode, you may need to delete the RNTester/build folder before rerunning detox build.
Building from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
