title: Share Audio file with VK application
body: <p>I'm trying to share audio files from my android app with other applications including VK: <a href="https://play.google.com/store/apps/details?id=com.vkontakte.android&amp;hl=en" rel="nofollow noreferrer">https://play.google.com/store/apps/details?id=com.vkontakte.android&amp;hl=en</a>
  The sharing functionality works fine with different applications, but not with VK. The code looks like:</p>
  
  <pre><code>    Intent intent = new Intent();
      intent.setAction(Intent.ACTION_SEND);
      intent.putExtra(Intent.EXTRA_STREAM, fileUri);
      intent.setType(context.getContentResolver().getType(fileUri));
      intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
      context.startActivity(intent);
  </code></pre>
  
  <p>In VK app during uploading process I get just "Error" without any information. In logcat I get the following error:</p>
