<p><a href="https://github.com/react-community/create-react-native-app">Create React Native App</a>
is the easiest way to start building a new React Native application. It allows
you to start a project without installing or configuring any tools to build
native code - no Xcode or Android Studio installation required (see
<a href="/react-native/docs/0.28/getting-started.html#caveats">Caveats</a>).</p>
<p>Assuming that you have <a href="https://nodejs.org/en/download/">Node</a> installed, you
can use npm to install the <code>create-react-native-app</code> command line utility:</p>
<pre><code class="hljs"><span class="hljs-string">npm </span><span class="hljs-string">install </span>-g <span class="hljs-built_in">create-react-native-app</span>
</code></pre>
<p>Then run the following commands to create a new React Native project called
&quot;AwesomeProject&quot;:</p>
<pre><code class="hljs"><span class="hljs-built_in">create-react-native-app</span> <span class="hljs-string">AwesomeProject
</span>
<span class="hljs-string">cd </span><span class="hljs-string">AwesomeProject
</span><span class="hljs-string">npm </span><span class="hljs-string">start
</span></code></pre>
<p>This will start a development server for you, and print a QR code in your
terminal.</p>

<p>Create React Native App makes it really easy to run your React Native app on a
physical device without setting up a development environment. If you want to run
your app on the iOS Simulator or an Android Virtual Device, please refer to the
instructions for building projects with native code to learn how to install
Xcode and set up your Android development environment.</p>
<p>Once you've set these up, you can launch your app on an Android Virtual Device
by running <code>npm run android</code>, or on the iOS Simulator by running <code>npm run ios</code>
(macOS only).</p>

<p>Because you don't build any native code when using Create React Native App to
create a project, it's not possible to include custom native modules beyond the
React Native APIs and components that are available in the Expo client app.</p>
<p>If you know that you'll eventually need to include your own native code, Create
React Native App is still a good way to get started. In that case you'll just
need to
&quot;<a href="https://github.com/react-community/create-react-native-app/blob/master/react-native-scripts/template/README.md#ejecting-from-create-react-native-app">eject</a>&quot;
eventually to create your own native builds. If you do eject, the &quot;Building
Projects with Native Code&quot; instructions will be required to continue working on
your project.</p>
<p>Create React Native App configures your project to use the most recent React
Native version that is supported by the Expo client app. The Expo client app
usually gains support for a given React Native version about a week after the
React Native version is released as stable. You can check
<a href="https://github.com/react-community/create-react-native-app/blob/master/VERSIONS.md">this document</a>
to find out what versions are supported.</p>
<p>If you're integrating React Native into an existing project, you'll want to skip
Create React Native App and go directly to setting up the native build
environment. Select &quot;Building Projects with Native Code&quot; above for instructions
on configuring a native build environment for React Native.</p>
<p><block class="native mac windows linux ios android" /></p>
<p>Follow these instructions if you need to build native code in your project. For example, if you are integrating React Native into an existing application, or if you "ejected" from <a href="getting-started.md" onclick="displayTab('guide', 'quickstart')">Create React Native App</a>, you'll need this section.</p>
<p>The instructions are a bit different depending on your development operating
system, and whether you want to start developing for iOS or Android. If you want
to develop for both iOS and Android, that's fine - you just have to pick one to
start with, since the setup is a bit different.</p>

Installing Xcode will also install the iOS Simulator and all the necessary tools
to build your iOS app.</p>
<p>If you have already installed Xcode on your system, make sure it is version 8 or
higher.</p>

Manager in Android Studio.</p>
<p>The SDK Manager can be accessed from the &quot;Welcome to Android Studio&quot; screen.

<p>You will need an Android device to run your React Native Android app. This can
be either a physical Android device, or more commonly, you can use an Android
Virtual Device which allows you to emulate an Android device on your computer.</p>
<p>Either way, you will need to prepare the device to run Android apps for
development.</p>

<p>If you have a physical Android device, you can use it for development in place
of an AVD by plugging it in to your computer using a USB cable and following the
instructions <a href="/react-native/docs/0.28/running-on-device.html">here</a>.</p>

<p>You can see the list of available Android Virtual Devices (AVDs) by opening the
&quot;AVD Manager&quot; from within Android Studio. Look for an icon that looks like this:</p>
<p><img src="/react-native/docs/assets/GettingStartedAndroidStudioAVD.png" alt="Android Studio AVD Manager"></p>
<p>If you have just installed Android Studio, you will likely need to
<a href="https://developer.android.com/studio/run/managing-avds.html">create a new AVD</a>.
Select &quot;Create Virtual Device...&quot;, then pick any Phone from the list and click
&quot;Next&quot;.</p>
