links.</p> 5<p>Every Link (URL) has a URL Scheme, some websites are prefixed with <code>https://</code> or <code>http://</code> and the <code>http</code> is the URL Scheme. Let's call it scheme for short.</p> 6<p>In addition to <code>https</code>, you're likely also familiar with the <code>mailto</code> scheme. When you open a link with the mailto scheme, your operating system will open an installed mail application. Similarly, there are schemes for making phone calls and sending SMS. Read more about <a href=#built-in-url-schemes>built-in URL</a> schemes below.</p> 7<p>Like using the mailto scheme, it's possible to link to other applications by using custom url schemes. For example, when you get a <strong>Magic Link</strong> email from Slack, the <strong>Launch Slack</strong> button is an anchor tag with an href that looks something like: <code>slack://secret/magic-login/other-secret</code>. Like with Slack, you can tell the operating system that you want to handle a custom scheme. When the Slack app opens, it receives the URL that was used to open it. This is often referred to as deep linking. Read more about how to <a href=#get-the-deep-link>get the deep link</a> into your app.</p> 8<p>A custom URL scheme isn't the only way to open your application on mobile. For example, if you want to email someone a link to be opened on mobile, using a custom URL scheme isn't ideal because the user might open the email on a desktop, where the link wouldn't work. Instead, you should use standard <code>https</code> links, such as <code>https://www.myapp.io/records/1234546</code>. On mobile, these links can be configured to open your app. On Android, this feature is called <strong>Deep Links</strong>, while on iOS, it is known as <strong>Universal Links</strong>.</p> 9<h3 class="anchor anchorWithStickyNavbar_JmGV" id=built-in-url-schemes>Built-in URL Schemes<a href=#built-in-url-schemes class=hash-link aria-label="Direct link to Built-in URL Schemes" title="Direct link to Built-in URL Schemes">​</a></h3> 10<p>As mentioned in the introduction, there are some URL schemes for core functionality that exist on every platform.

45<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> 46<p>The <code>Promise</code> will reject on Android if it was impossible to check if the URL can be opened or when targeting Android 11 (SDK 30) if you didn't specify the relevant intent queries in <code>AndroidManifest.xml</code>. Similarly on iOS, the promise will reject if you didn't add the specific scheme in the <code>LSApplicationQueriesSchemes</code> key inside <code>Info.plist</code> (see bellow).</p> 47<p><strong>Parameters:</strong></p> 48<table><thead><tr><th>Name<th>Type<th>Description<tbody><tr><td>url <div class="label basic required">Required</div><td>string<td>The URL to open.</table> 49<blockquote> 50<p>For web URLs, the protocol (<code>"http://"</code>, <code>"https://"</code>) must be set accordingly!</p> 51</blockquote> 52<blockquote> 53<p>This method has limitations on iOS 9+.

After reaching that limit, subsequent calls always resolve to <code>false</code>. If the user reinstalls or upgrades the app, iOS resets the limit.</li> 56</ul> 57<p>As of iOS 9, your app also needs to provide the <code>LSApplicationQueriesSchemes</code> key inside <code>Info.plist</code> or <code>canOpenURL()</code> will always resolve to <code>false</code>.</p> 58</blockquote> 59<blockquote> 60<p>When targeting Android 11 (SDK 30) you must specify the intents for the schemes you want to handle in <code>AndroidManifest.xml</code>. A list of common intents can be found <a href=https://developer.android.com/guide/components/intents-common target=_blank rel="noopener noreferrer">here</a>.</p> 61<p>For example to handle
