8<p>You will need Node, Watchman, the React Native command line interface, a JDK, and Android Studio.</p>
9<p>While you can use any editor of your choice to develop your app, you will need to install Android Studio in order to set up the necessary tooling to build your React Native app for Android.</p>
10<h3>Node & Watchman</h3>
11<p>We recommend installing Node and Watchman using <a href=https://brew.sh/ target=_blank rel="noopener noreferrer">Homebrew</a>. Run the following commands in a Terminal after installing Homebrew:</p>
12<div class="language-shell codeBlockContainer_mQmQ theme-code-block" style=--prism-color:#FFFFFF;--prism-background-color:#282C34><div class=codeBlockTitle_kY6l>shell</div><div class=codeBlockContent_t_Hd><pre tabindex=0 class="prism-code language-shell codeBlock_RMoD thin-scrollbar" style=color:#FFFFFF;background-color:#282C34><code class=codeBlockLines_AclH><span class=token-line style=color:#FFFFFF><span class="token plain">brew </span><span class="token function" style=color:#79b6f2>install</span><span class="token plain"> </span><span class="token function" style=color:#79b6f2>node</span><span class="token plain"></span><br></span><span class=token-line style=color:#FFFFFF><span class="token plain">brew </span><span class="token function" style=color:#79b6f2>install</span><span class="token plain"> watchman</span><br></span></code></pre></div></div>
13<p>If you have already installed Node on your system, make sure it is Node 18.18 or newer.</p>
14<p><a href=https://facebook.github.io/watchman target=_blank rel="noopener noreferrer">Watchman</a> is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.</p>
15<h3>Java Development Kit</h3>
16<p>We recommend installing the OpenJDK distribution called Azul <strong>Zulu</strong> using <a href=https://brew.sh/ target=_blank rel="noopener noreferrer">Homebrew</a>. Run the following commands in a Terminal after installing Homebrew:</p>

18<p>After opening Finder, double click the <code>Double-Click to Install Azul Zulu JDK 17.pkg</code> package to install the JDK.</p>
19<p>After the JDK installation, add or update your <code>JAVA_HOME</code> environment variable in <code>~/.zshrc</code> (or in <code>~/.bash_profile</code>).</p>
20<p>If you used above steps, JDK will likely be located at <code>/Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home</code>:</p>
21<div class="language-shell codeBlockContainer_mQmQ theme-code-block" style=--prism-color:#FFFFFF;--prism-background-color:#282C34><div class=codeBlockTitle_kY6l>shell</div><div class=codeBlockContent_t_Hd><pre tabindex=0 class="prism-code language-shell codeBlock_RMoD thin-scrollbar" style=color:#FFFFFF;background-color:#282C34><code class=codeBlockLines_AclH><span class=token-line style=color:#FFFFFF><span class="token builtin class-name" style=color:#fac863>export</span><span class="token plain"> </span><span class="token assign-left variable" style=color:#cb4b16>JAVA_HOME</span><span class="token operator" style=color:#fc929e>=</span><span class="token plain">/Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home</span><br></span></code></pre></div></div>
22<p>The Zulu OpenJDK distribution offers JDKs for <strong>both Intel and M1 Macs</strong>. This will make sure your builds are faster on M1 Macs compared to using an Intel-based JDK.</p>
23<p>If you have already installed JDK on your system, we recommend JDK 17. You may encounter problems using higher JDK versions.</p>
24<h3>Android development environment</h3>
25<p>Setting up your development environment can be somewhat tedious if you're new to Android development. If you're already familiar with Android development, there are a few things you may need to configure. In either case, please make sure to carefully follow the next few steps.</p>
26<h4 id=android-studio>1. Install Android Studio</h4>
27<p><a href=https://developer.android.com/studio/index.html target=_blank rel="noopener noreferrer">Download and install Android Studio</a>. While on Android Studio installation wizard, make sure the boxes next to all of the following items are checked:</p>
28<ul>
29<li><code>Android SDK</code></li>
30<li><code>Android SDK Platform</code></li>
31<li><code>Android Virtual Device</code></li>
32</ul>
33<p>Then, click "Next" to install all of these components.</p>
34<blockquote>
35<p>If the checkboxes are grayed out, you will have a chance to install these components later on.</p>
36</blockquote>
37<p>Once setup has finalized and you're presented with the Welcome screen, proceed to the next step.</p>
38<h4 id=android-sdk>2. Install the Android SDK</h4>
39<p>Android Studio installs the latest Android SDK by default. Building a React Native app with native code, however, requires the <code>Android 15 (VanillaIceCream)</code> SDK in particular. Additional Android SDKs can be installed through the SDK Manager in Android Studio.</p>
40<p>To do that, open Android Studio, click on "More Actions" button and select "SDK Manager".</p>
41<p><img decoding=async loading=lazy alt="Android Studio Welcome" src=/assets/images/GettingStartedAndroidStudioWelcomeMacOS-64c618ea062865fedece6dd5f7b78fa4.png width=704 height=550 class=img_SS3x></p>
42<blockquote>
43<p>The SDK Manager can also be found within the Android Studio "Settings" dialog, under <strong>Languages & Frameworks</strong> → <strong>Android SDK</strong>.</p>
44</blockquote>
45<p>Select the "SDK Platforms" tab from within the SDK Manager, then check the box next to "Show Package Details" in the bottom right corner. Look for and expand the <code>Android 15 (VanillaIceCream)</code> entry, then make sure the following items are checked:</p>
46<ul>
47<li><code>Android SDK Platform 35</code></li>
48<li><code>Intel x86 Atom_64 System Image</code> or <code>Google APIs Intel x86 Atom System Image</code> or (for Apple M1 Silicon) <code>Google APIs ARM 64 v8a System Image</code></li>
49</ul>
50<p>Next, select the "SDK Tools" tab and check the box next to "Show Package Details" here as well. Look for and expand the "Android SDK Build-Tools" entry, then make sure that <code>35.0.0</code> is selected.</p>
51<p>Finally, click "Apply" to download and install the Android SDK and related build tools.</p>
52<h4>3. Configure the ANDROID_HOME environment variable</h4>
53<p>The React Native tools require some environment variables to be set up in order to build apps with native code.</p>
54<p>Add the following lines to your <code>~/.zprofile</code> or <code>~/.zshrc</code> (if you are using <code>bash</code>, then <code>~/.bash_profile</code> or <code>~/.bashrc</code>) config file:</p>
55<div class="language-shell codeBlockContainer_mQmQ theme-code-block" style=--prism-color:#FFFFFF;--prism-background-color:#282C34><div class=codeBlockTitle_kY6l>shell</div><div class=codeBlockContent_t_Hd><pre tabindex=0 class="prism-code language-shell codeBlock_RMoD thin-scrollbar" style=color:#FFFFFF;background-color:#282C34><code class=codeBlockLines_AclH><span class=token-line style=color:#FFFFFF><span class="token builtin class-name" style=color:#fac863>export</span><span class="token plain"> </span><span class="token assign-left variable" style=color:#cb4b16>ANDROID_HOME</span><span class="token operator" style=color:#fc929e>=</span><span class="token environment constant" style=color:#5a9bcf>$HOME</span><span class="token plain">/Library/Android/sdk</span><br></span><span class=token-line style=color:#FFFFFF><span class="token plain"></span><span class="token builtin class-name" style=color:#fac863>export</span><span class="token plain"> </span><span class="token assign-left variable environment constant" style=color:#5a9bcf>PATH</span><span class="token operator" style=color:#fc929e>=</span><span class="token environment constant" style=color:#5a9bcf>$PATH</span><span class="token builtin class-name" style=color:#fac863>:</span><span class="token variable" style=color:#cb4b16>$ANDROID_HOME</span><span class="token plain">/emulator</span><br></span><span class=token-line style=color:#FFFFFF><span class="token plain"></span><span class="token builtin class-name" style=color:#fac863>export</span><span class="token plain"> </span><span class="token assign-left variable environment constant" style=color:#5a9bcf>PATH</span><span class="token operator" style=color:#fc929e>=</span><span class="token environment constant" style=color:#5a9bcf>$PATH</span><span class="token builtin class-name" style=color:#fac863>:</span><span class="token variable" style=color:#cb4b16>$ANDROID_HOME</span><span class="token plain">/platform-tools</span><br></span></code></pre></div></div>
56<p>Run <code>source ~/.zprofile</code> (or <code>source ~/.bash_profile</code> for <code>bash</code>) to load the config into your current shell. Verify that ANDROID_HOME has been set by running <code>echo $ANDROID_HOME</code> and the appropriate directories have been added to your path by running <code>echo $PATH</code>.</p>
57<blockquote>
58<p>Please make sure you use the correct Android SDK path. You can find the actual location of the SDK in the Android Studio "Settings" dialog, under <strong>Languages & Frameworks</strong> → <strong>Android SDK</strong>.</p>
59</blockquote>
60<h2>Preparing the Android device</h2>
61<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>
62<p>Either way, you will need to prepare the device to run Android apps for development.</p>
63<h3>Using a physical device</h3>
64<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=/docs/running-on-device>here</a>.</p>
65<h3>Using a virtual device</h3>
66<p>If you use Android Studio to open <code>./AwesomeProject/android</code>, you can see the list of available Android Virtual Devices (AVDs) by opening the "AVD Manager" from within Android Studio. Look for an icon that looks like this:</p>
67<img src=/docs/assets/GettingStartedAndroidStudioAVD.svg alt="Android Studio AVD Manager" width=100>
68<p>If you have recently installed Android Studio, you will likely need to <a href=https://developer.android.com/studio/run/managing-avds.html target=_blank rel="noopener noreferrer">create a new AVD</a>. Select "Create Virtual Device...", then pick any Phone from the list and click "Next", then select the <strong>VanillaIceCream</strong> API Level 35 image.</p>
69<p>Click "Next" then "Finish" to create your AVD. At this point you should be able to click on the green triangle button next to your AVD to launch it.</p>
70<h3>That's it!</h3>
71<p>Congratulations! You successfully set up your development environment.</p>

84<p><a href=https://facebook.github.io/watchman target=_blank rel="noopener noreferrer">Watchman</a> is a tool by Facebook for watching changes in the filesystem. It is highly recommended you install it for better performance.</p>
85<h3 class="anchor anchorWithStickyNavbar_JmGV" id=xcode>Xcode<a href=#xcode class=hash-link aria-label="Direct link to Xcode" title="Direct link to Xcode"></a></h3>
86<p>Please use the <strong>latest version</strong> of Xcode.</p>

95<p><a href=https://cocoapods.org/ target=_blank rel="noopener noreferrer">CocoaPods</a> is one of the dependency management system available for iOS. CocoaPods is a Ruby <a href=https://en.wikipedia.org/wiki/RubyGems target=_blank rel="noopener noreferrer">gem</a>. You can install CocoaPods using the version of Ruby that ships with the latest version of macOS.</p>

98<p>Starting from React Native version 0.69, it is possible to configure the Xcode environment using the <code>.xcode.env</code> file provided by the template.</p>
99<p>The <code>.xcode.env</code> file contains an environment variable to export the path to the <code>node</code> executable in the <code>NODE_BINARY</code> variable.
100This is the <strong>suggested approach</strong> to decouple the build infrastructure from the system version of <code>node</code>. You should customize this variable with your own path or your own <code>node</code> version manager, if it differs from the default.</p>
101<p>On top of this, it's possible to add any other environment variable and to source the <code>.xcode.env</code> file in your build script phases. If you need to run script that requires some specific environment, this is the <strong>suggested approach</strong>: it allows to decouple the build phases from a specific environment.</p>

112<p>While you can use any editor of your choice to develop your app, you will need to install Android Studio in order to set up the necessary tooling to build your React Native app for Android.</p>
113<h3 id=jdk>Node, JDK</h3>
114<p>We recommend installing Node via <a href=https://chocolatey.org/install target=_blank rel="noopener noreferrer">Chocolatey</a>, a popular package manager for Windows.</p>
115<p>It is recommended to use an LTS version of Node. If you want to be able to switch between different versions, you might want to install Node via <a href=https://github.com/coreybutler/nvm-windows target=_blank rel="noopener noreferrer">nvm-windows</a>, a Node version manager for Windows.</p>
116<p>React Native also requires <a href=https://openjdk.java.net/projects/jdk/17/ target=_blank rel="noopener noreferrer">Java SE Development Kit (JDK)</a>, which can be installed using Chocolatey as well.</p>
117<p>Open an Administrator Command Prompt (right click Command Prompt and select "Run as Administrator"), then run the following command:</p>

123<blockquote>
124<p>If you're using the latest version of Java Development Kit, you'll need to change the Gradle version of your project so it can recognize the JDK. You can do that by going to <code>{project root folder}\android\gradle\wrapper\gradle-wrapper.properties</code> and changing the <code>distributionUrl</code> value to upgrade the Gradle version.

126<h3>Android development environment</h3>
127<p>Setting up your development environment can be somewhat tedious if you're new to Android development. If you're already familiar with Android development, there are a few things you may need to configure. In either case, please make sure to carefully follow the next few steps.</p>
128<h4 id=android-studio>1. Install Android Studio</h4>
129<p><a href=https://developer.android.com/studio/index.html target=_blank rel="noopener noreferrer">Download and install Android Studio</a>. While on Android Studio installation wizard, make sure the boxes next to all of the following items are checked:</p>
130<ul>
131<li><code>Android SDK</code></li>
132<li><code>Android SDK Platform</code></li>
133<li><code>Android Virtual Device</code></li>
134<li>If you are not already using Hyper-V: <code>Performance (Intel ® HAXM)</code> (<a href=https://android-developers.googleblog.com/2018/07/android-emulator-amd-processor-hyper-v.html target=_blank rel="noopener noreferrer">See here for AMD or Hyper-V</a>)</li>
135</ul>
136<p>Then, click "Next" to install all of these components.</p>
137<blockquote>
138<p>If the checkboxes are grayed out, you will have a chance to install these components later on.</p>
139</blockquote>
140<p>Once setup has finalized and you're presented with the Welcome screen, proceed to the next step.</p>
141<h4 id=android-sdk>2. Install the Android SDK</h4>
142<p>Android Studio installs the latest Android SDK by default. Building a React Native app with native code, however, requires the <code>Android 15 (VanillaIceCream)</code> SDK in particular. Additional Android SDKs can be installed through the SDK Manager in Android Studio.</p>
143<p>To do that, open Android Studio, click on "More Actions" button and select "SDK Manager".</p>
144<p><img decoding=async loading=lazy alt="Android Studio Welcome" src=/assets/images/GettingStartedAndroidStudioWelcomeWindows-ce20d1230828a1a26e143e3a4145f1df.png width=786 height=593 class=img_SS3x></p>
145<blockquote>
146<p>The SDK Manager can also be found within the Android Studio "Settings" dialog, under <strong>Languages & Frameworks</strong> → <strong>Android SDK</strong>.</p>
147</blockquote>
148<p>Select the "SDK Platforms" tab from within the SDK Manager, then check the box next to "Show Package Details" in the bottom right corner. Look for and expand the <code>Android 15 (VanillaIceCream)</code> entry, then make sure the following items are checked:</p>
149<ul>
150<li><code>Android SDK Platform 35</code></li>
151<li><code>Intel x86 Atom_64 System Image</code> or <code>Google APIs Intel x86 Atom System Image</code></li>
152</ul>
153<p>Next, select the "SDK Tools" tab and check the box next to "Show Package Details" here as well. Look for and expand the <code>Android SDK Build-Tools</code> entry, then make sure that <code>35.0.0</code> is selected.</p>
154<p>Finally, click "Apply" to download and install the Android SDK and related build tools.</p>
155<h4>3. Configure the ANDROID_HOME environment variable</h4>
156<p>The React Native tools require some environment variables to be set up in order to build apps with native code.</p>
157<ol>
158<li>Open the <strong>Windows Control Panel.</strong></li>
159<li>Click on <strong>User Accounts,</strong> then click <strong>User Accounts</strong> again</li>
160<li>Click on <strong>Change my environment variables</strong></li>
161<li>Click on <strong>New...</strong> to create a new <code>ANDROID_HOME</code> user variable that points to the path to your Android SDK:</li>

184<h2>Preparing the Android device</h2>
185<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>
186<p>Either way, you will need to prepare the device to run Android apps for development.</p>
187<h3>Using a physical device</h3>
188<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=/docs/running-on-device>here</a>.</p>
189<h3>Using a virtual device</h3>
190<p>If you use Android Studio to open <code>./AwesomeProject/android</code>, you can see the list of available Android Virtual Devices (AVDs) by opening the "AVD Manager" from within Android Studio. Look for an icon that looks like this:</p>
191<img src=/docs/assets/GettingStartedAndroidStudioAVD.svg alt="Android Studio AVD Manager" width=100>
192<p>If you have recently installed Android Studio, you will likely need to <a href=https://developer.android.com/studio/run/managing-avds.html target=_blank rel="noopener noreferrer">create a new AVD</a>. Select "Create Virtual Device...", then pick any Phone from the list and click "Next", then select the <strong>VanillaIceCream</strong> API Level 35 image.</p>
193<blockquote>
194<p>If you don't have HAXM installed, click on "Install HAXM" or follow <a href=https://github.com/intel/haxm/wiki/Installation-Instructions-on-Windows target=_blank rel="noopener noreferrer">these instructions</a> to set it up, then go back to the AVD Manager.</p>
195</blockquote>
196<p>Click "Next" then "Finish" to create your AVD. At this point you should be able to click on the green triangle button next to your AVD to launch it.</p>
197<h3>That's it!</h3>
198<p>Congratulations! You successfully set up your development environment.</p>

207<p>You will need Node, the React Native command line interface, a JDK, and Android Studio.</p>
208<p>While you can use any editor of your choice to develop your app, you will need to install Android Studio in order to set up the necessary tooling to build your React Native app for Android.</p>
209<h3>Node</h3>
210<p>Follow the <a href=https://nodejs.org/en/download/package-manager/ target=_blank rel="noopener noreferrer">installation instructions for your Linux distribution</a> to install Node 18.18 or newer.</p>
211<h3>Java Development Kit</h3>
212<p>React Native currently recommends version 17 of the Java SE Development Kit (JDK). You may encounter problems using higher JDK versions. You may download and install <a href=https://openjdk.java.net target=_blank rel="noopener noreferrer">OpenJDK</a> from <a href=https://adoptopenjdk.net/ target=_blank rel="noopener noreferrer">AdoptOpenJDK</a> or your system packager.</p>

It is highly recommended you install it for better performance and increased compatibility in certain edge cases (translation: you may be able to get by without installing this, but your mileage may vary; installing this now may save you from a headache later).</p>

256<h2>Preparing the Android device</h2>
257<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>
258<p>Either way, you will need to prepare the device to run Android apps for development.</p>
259<h3>Using a physical device</h3>
260<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=/docs/running-on-device>here</a>.</p>
261<h3>Using a virtual device</h3>
262<p>If you use Android Studio to open <code>./AwesomeProject/android</code>, you can see the list of available Android Virtual Devices (AVDs) by opening the "AVD Manager" from within Android Studio. Look for an icon that looks like this:</p>
263<img src=/docs/assets/GettingStartedAndroidStudioAVD.svg alt="Android Studio AVD Manager" width=100>
264<p>If you have recently installed Android Studio, you will likely need to <a href=https://developer.android.com/studio/run/managing-avds.html target=_blank rel="noopener noreferrer">create a new AVD</a>. Select "Create Virtual Device...", then pick any Phone from the list and click "Next", then select the <strong>VanillaIceCream</strong> API Level 35 image.</p>
265<blockquote>
266<p>We recommend configuring <a href=https://developer.android.com/studio/run/emulator-acceleration.html#vm-linux target=_blank rel="noopener noreferrer">VM acceleration</a> on your system to improve performance. Once you've followed those instructions, go back to the AVD Manager.</p>
267</blockquote>
268<p>Click "Next" then "Finish" to create your AVD. At this point you should be able to click on the green triangle button next to your AVD to launch it.</p>
269<h3>That's it!</h3>
270<p>Congratulations! You successfully set up your development environment.</p>
