title: Xamarin.Forms - Open file with default app
body: <p>I need to open a file from storage. I used <code>Launcher.OpenAsync()</code>, but it always tries to open the file in PDF reader. Is there any other way to open a file with default app on Android?</p>
  
  <p>This is the code I have already tried. </p>
  
  <pre class="lang-cs prettyprint-override"><code>private void OpenDocument(string filePath)
  {
      var localFile = "file://" + filePath;
      Launcher.OpenAsync(localFile);
  }
  </code></pre>
