title: Open downloaded file using intent
body: <p>I make a retrofit call to my own API that provides me a list of files with the following content:</p>
  
  <pre><code>[
    {
      "name": "Example_file.jpg",
      "ext": "jpg",
      "b64": "data in base 64 format"
    }
  ]
  </code></pre>
  
  <p>I show this list of files using a recycler view. When I click on one element from recycler view, I decode the base64 content and generate a file like the following:</p>
  
  <pre><code>val content = Base64.getDecoder().decode(file.getB64()!!.toByteArray())
  val os = FileOutputStream(getExternalStorageDirectory().path + file.getName(), true)
  os.write(content)
  os.flush()
  os.close()
  </code></pre>
  
  <p>After this is complete, I would like to open this file using the Android file manager.</p>
  
  <p>How can I force to open that stored file?</p>
