<h3>Projects with Native Code Only</h3>
<p>
The following section only applies to projects with native code exposed. If you are using the managed `expo-cli` workflow, see the guide on <a href="http://docs.expo.io/versions/latest/workflow/linking/">Linking</a> in the Expo documentation for the appropriate alternative.

<p><code>Linking</code> gives you a general interface to interact with both incoming and outgoing app links.</p>

<blockquote>
<p>For instructions on how to add support for deep linking on Android, refer to <a href="http://developer.android.com/training/app-indexing/deep-linking.html#adding-filters">Enabling Deep Links for App Content - Add Intent Filters for Your Deep Links</a>.</p>
</blockquote>
<p>If you wish to receive the intent in an existing instance of MainActivity, you may set the <code>launchMode</code> of MainActivity to <code>singleTask</code> in <code>AndroidManifest.xml</code>. See <a href="http://developer.android.com/guide/topics/manifest/activity-element.html"><code>&lt;activity&gt;</code></a> documentation for more information.</p>
<pre><code class="hljs css language-xml"><span class="hljs-tag">&lt;<span class="hljs-name">activity</span>
<span class="hljs-attr">android:name</span>=<span class="hljs-string">".MainActivity"</span>
<span class="hljs-attr">android:launchMode</span>=<span class="hljs-string">"singleTask"</span>&gt;</span>
</code></pre>
<p>NOTE: On iOS, you'll need to link <code>RCTLinking</code> to your project by following the steps described <a href="/react-native/docs/linking-libraries-ios#manual-linking">here</a>. If you also want to listen to incoming app links during your app's execution, you'll need to add the following lines to your <code>*AppDelegate.m</code>:</p>
<pre><code class="hljs css language-objectivec"><span class="hljs-comment">// iOS 9.x or newer</span>
<span class="hljs-meta">#import <span class="hljs-meta-string">&lt;React/RCTLinkingManager.h&gt;</span></span>
- (<span class="hljs-built_in">BOOL</span>)application:(<span class="hljs-built_in">UIApplication</span> *)application
openURL:(<span class="hljs-built_in">NSURL</span> *)url
options:(<span class="hljs-built_in">NSDictionary</span>&lt;<span class="hljs-built_in">UIApplicationOpenURLOptionsKey</span>,<span class="hljs-keyword">id</span>&gt; *)options
{
<span class="hljs-keyword">return</span> [RCTLinkingManager application:application openURL:url options:options];
}
</code></pre>
<p>If you're targeting iOS 8.x or older, you can use the following code instead:</p>
<pre><code class="hljs css language-objectivec"><span class="hljs-comment">// iOS 8.x or older</span>
<span class="hljs-meta">#import <span class="hljs-meta-string">&lt;React/RCTLinkingManager.h&gt;</span></span>
- (<span class="hljs-built_in">BOOL</span>)application:(<span class="hljs-built_in">UIApplication</span> *)application openURL:(<span class="hljs-built_in">NSURL</span> *)url
sourceApplication:(<span class="hljs-built_in">NSString</span> *)sourceApplication annotation:(<span class="hljs-keyword">id</span>)annotation
{
<span class="hljs-keyword">return</span> [RCTLinkingManager application:application openURL:url
sourceApplication:sourceApplication annotation:annotation];
}
</code></pre>
<p>If your app is using <a href="https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/AppSearch/UniversalLinks.html">Universal Links</a>, you'll need to add the following code as well:</p>
<pre><code class="hljs css language-objectivec">- (<span class="hljs-built_in">BOOL</span>)application:(<span class="hljs-built_in">UIApplication</span> *)application continueUserActivity:(<span class="hljs-keyword">nonnull</span> <span class="hljs-built_in">NSUserActivity</span> *)userActivity
restorationHandler:(<span class="hljs-keyword">nonnull</span> <span class="hljs-keyword">void</span> (^)(<span class="hljs-built_in">NSArray</span>&lt;<span class="hljs-keyword">id</span>&lt;<span class="hljs-built_in">UIUserActivityRestoring</span>&gt;&gt; * _Nullable))restorationHandler
{
<span class="hljs-keyword">return</span> [RCTLinkingManager application:application
continueUserActivity:userActivity
restorationHandler:restorationHandler];
}
</code></pre>
<p>And then on your React component you'll be able to listen to the events on <code>Linking</code> as follows:</p>
<pre><code class="hljs css language-jsx"><span class="token function">componentDidMount</span><span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token punctuation">{</span>
Linking<span class="token punctuation">.</span><span class="token function">addEventListener</span><span class="token punctuation">(</span><span class="token string">'url'</span><span class="token punctuation">,</span> <span class="token keyword">this</span><span class="token punctuation">.</span>_handleOpenURL<span class="token punctuation">)</span><span class="token punctuation">;</span>

<p>Try to open the given <code>url</code> with any of the installed apps.</p>
<p>You can use other URLs, like a location (e.g. &quot;geo:37.484847,-122.148386&quot; on Android or &quot;<a href="http://maps.apple.com/?ll=37.484847,-122.148386">http://maps.apple.com/?ll=37.484847,-122.148386</a>&quot; on iOS), a contact, or any other URL that can be opened with the installed apps.</p>
<p>The method returns a <code>Promise</code> object. If the user confirms the open dialog or the url automatically opens, the promise is resolved. If the user cancels the open dialog or there are no registered applications for the url, the promise is rejected.</p>
<p><strong>Parameters:</strong></p>
<table>

<tr><td>url</td><td>string</td><td>Yes</td><td>The URL to open.</td></tr>
</tbody>

<blockquote>
<p>This method will fail if the system doesn't know how to open the specified URL. If you're passing in a non-http(s) URL, it's best to check {@code canOpenURL} first.</p>
</blockquote>
<blockquote>
<p>For web URLs, the protocol (&quot;http://&quot;, &quot;https://&quot;) must be set accordingly!</p>

</code></pre>
<p>Determine whether or not an installed app can handle a given URL.</p>
<p>The method returns a <code>Promise</code> object. When it is determined whether or not the given URL can be handled, the promise is resolved and the first parameter is whether or not it can be opened.</p>
<p>The <code>Promise</code> will reject on Android if it was impossible to check if the URL can be opened, and on iOS if you didn't add the specific scheme in the <code>LSApplicationQueriesSchemes</code> key inside <code>Info.plist</code> (see bellow).</p>
<p><strong>Parameters:</strong></p>

<blockquote>
<p>For web URLs, the protocol (&quot;http://&quot;, &quot;https://&quot;) must be set accordingly!</p>
</blockquote>
<blockquote>
<p>As of iOS 9, your app needs to provide the <code>LSApplicationQueriesSchemes</code> key inside <code>Info.plist</code> or canOpenURL will always return false.</p>
</blockquote>
<blockquote>
<p>This method has limitations on iOS 9+. From <a href="https://developer.apple.com/documentation/uikit/uiapplication/1622952-canopenurl">the official Apple documentation</a>:</p>
</blockquote>
<blockquote>
<p>If your app is linked against an earlier version of iOS but is running in iOS 9.0 or later, you can call this method up to 50 times. After reaching that limit, subsequent calls always return false. If the user reinstalls or upgrades the app, iOS resets the limit.</p>
