Summary: This is **a critical issue**. The issue arises when incremental networking is enabled from JS by setting `onprogress` or `onload` on an `XMLHttpRequest` object. The results:   Unicode characters get corrupted seemingly in random. The issue is from the way Unicode character parsing is handled in `RCTNetworking.mm`. When incremental networking is enabled, each chunk of data is decoded and passed to JS: ```objective-c incrementalDataBlock = ^(NSData *data, int64_t progress, int64_t total) { NSString *responseString = [RCTNetworking decodeTextData:data fromResponse:task.response]; if (!responseString) { RCTLogWarn(@"Received data was not a string, or was not a recognised encoding."); return; } NSArray<id> *responseJSON = @[task.requestID, responseString, @(prog Closes https://github.com/facebook/react-native/pull/10110 Reviewed By: yungsters Differential Revision: D4101533 Pulled By: fkgozali fbshipit-source-id: 2674eaf0dd4568889070c6cde5cdf12edc5be521
UIExplorer
The UIExplorer is a sample app that 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
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
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 :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer 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 uiexplorer
buck install -r uiexplorer
./packager/packager.sh
Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).
Built 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).
