Summary:Thanks for submitting a pull request! Please provide enough information so that others can review your pull request: (You can skip this if you're fixing a typo or adding an app to the Showcase.) Explain the **motivation** for making this change. What existing problem does the pull request solve? Prefer **small pull requests**. These are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it. ✅ **Test plan (required)** Demonstrate the code is solid. Example: The exact commands you ran and their output, screenshots / videos if the pull request changes UI. Make sure tests pass on both Travis and Circle CI. **Code formatting** Look around. Match the style of the rest of the codebase. See also the simple [style guide](https://github.com/facebook/react-native/blob/master/CONTRIBUTING.md#style-guide). Closes https://github.com/facebook/react-native/pull/6867 Differential Revision: D3186273 Pulled By: ericvicenti fb-gh-sync-id: 35e82fe4389a271a30c49dd5a3bcbab7ac29a0cd fbshipit-source-id: 35e82fe4389a271a30c49dd5a3bcbab7ac29a0cd
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).
