title: Check if a certain app is installed on device with React Native
body: <p>From my app, I'm trying to check if another app is installed (in my example, Google Maps). So I tried to use:</p>
  
  <pre><code>Linking.canOpenURL('comgooglemaps://?daddr=' + address + '&amp;directionsmode=walking').then(supported =&gt; {...}).catch(err =&gt; console.error('An error occurred', err));
  </code></pre>
  
  <p>But it returns that it's not supported so it's like Google Maps is not installed. Do you know a way to solve this issue?</p>
