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). the iOS run is now aligned with Android and can be run preferably from the command line.

Requirements
- OS X - This guide assumes OS X which is needed for iOS development.
- Homebrew is the recommended way to install Watchman and Flow.
- Install Node.js 4.0 or newer.
- Install nvm with its setup instructions here. Then run
nvm install node && nvm alias default node
, which installs the latest version of Node.js and sets up your terminal so you can run it by typingnode
. With nvm you can install multiple versions of Node.js and easily switch between them. - New to npm?
brew install watchman
. We recommend installing watchman, otherwise you might hit a node file watching bug.brew install flow
, if you want to use flow.
We recommend periodically running brew update && brew upgrade
to keep your programs up-to-date.
iOS Setup
Xcode 7.0 or higher is required. It can be installed from the App Store.
Android Setup
To write React Native apps for Android, you will need to install the Android SDK (and an Android emulator if you want to work on your app without having to use a physical device). See Android setup guide for instructions on how to set up your Android environment.
NOTE: There is experimental Windows and Linux support for Android development.
Quick start
Install the React Native command line tools:
$ npm install -g react-native-cli
NOTE: If you see the error, EACCES: permission denied
, please run the command: sudo npm install -g react-native-cli
.
Create a React Native project:
$ react-native init AwesomeProject
To run the iOS app:
$ cd AwesomeProject
$ react-native run-ios
OR openios/AwesomeProject.xcodeproj
and hit "Run" button in Xcode- Open
index.ios.js
in your text editor of choice and edit some lines. - Hit ⌘-R in your iOS simulator to reload the app and see your change!
Note: If you are using an iOS device, see the Running on iOS Device page.
To run the Android app:
$ cd AwesomeProject
$ react-native run-android
- Open
index.android.js
in your text editor of choice and edit some lines. - Press the menu button (F2 by default, or ⌘-M in Genymotion) and select Reload JS to see your change!
- Run
adb logcat *:S ReactNative:V ReactNativeJS:V
in a terminal to see your app's logs
Note: If you are using an Android device, see the Running on Android Device page.
Congratulations! You've successfully run and modified your first React Native app.
If you run into any issues getting started, see the troubleshooting page.
Adding Android to an existing React Native project
If you already have a (iOS-only) React Native project and want to add Android support, you need to execute the following commands in your existing project directory:
- Update the
react-native
dependency in yourpackage.json
file to the latest version $ npm install
$ react-native android
