title: How to expose component from installed app to be visible to instant app?
body: <p>From the <a href="https://developer.android.com/topic/instant-apps/faqs.html" rel="noreferrer">developer document of Instant Apps</a></p>
  
  <blockquote>
    <p>Installed apps can make themselves available to interact with instant through explicit intents.</p>
  </blockquote>
  
  <p>And later, it is mentioned that instant apps cannot</p>
  
  <blockquote>
    <p>Discover the list of installed apps on the device, <strong>unless the installed apps have made themselves discoverable to instant apps</strong>.</p>
  </blockquote>
  
  <p>But I can't find the details about how to expose the component of an installed app or any part of an app, for that matter, to be visible (and accessible) by instant app. And any limitation on that? (supported component types and etc.)</p>
