title: Mime type for .txt files?
body: <p>I´m trying to share a <code>.txt</code> file with share intent. If I set "text/plain" as mime type, it reads the content like text not like text file, then the options given in the share menu are Whatsapp, Line, etc..</p>
  
  <p>Does anybody know how to configure the share intent so that the share options are only the programs that are able to send a <code>.txt</code> file (Gmail, Dropbox, etc.. but not Whatsapp..)? Thanks</p>
