title: Installing APK from email attachment
body: <p><br>
  Whenever i send a .apk file via email as an attachment and then open the .apk-file in my phone from my email-account, i get a parsing error.<br>
  However if i put the .apk on my website and provide a URL to it, it works like a charm.</p>
  
  <p>A bug? Just me? Am i doing it wrong?<br>
  Thanks</p>
