title: How do I get the MIME Type from a URI with scheme == "android.resource"
body: <p>I know how to get the MIME Type from an URI when the scheme is "content" or "file". However, I cannot find any solution when the scheme is "android.resource". For example, I have <code>res/raw/video.mp4</code>.</p>
  
  <pre><code>val uri = Uri.parse("android.resource://$packageName/${R.raw.video}")
  </code></pre>
  
  <p>The uri is good because I can do the following</p>
  
  <pre><code>videoView.setVideoURI(uri)
  videoView.start()
  </code></pre>
  
  <p>Given such an URI, how can I get its mime type (should be "video/mp4" in this case)?</p>
