title: Open android app from webView inside another android app
body: <p>In my app there is a WebView to which I load a website from server. 
  There are two cases:</p>
  
  <ol>
  <li><p>On the loaded website there is a button which should lead to an another app. I know it can be handled like <a href="https://developer.chrome.com/multidevice/android/intents" rel="nofollow noreferrer">this</a>:</p>
  
  <pre><code>&lt;a href = "intent://scan/#Intent;scheme=zxing;package=com.google.zxing.client.android;end"&gt; Click me &lt;/a&gt;
  </code></pre></li>
  </ol>
  
  <p>but this doesn't work in the WebView (only in a standalone browser)! I tried to handle it in shouldOverrideUrlLoading and redirect to an external browser with Intent, but the URI with "intent://" URL is not recognised and cannot be opened.</p>
  
  <ol start="2">
  <li>The link I get from server is the 'intent' link.</li>
  </ol>
  
  <p>The behaviour in both cases should be the same: if app is installed open the app, if not open Google Play do download the app.</p>
  
  <p>Is there any way to do this?</p>
