title: Android facebook 4.0.0 share dialog does not share the content
body: <p>For hours I have been trying to share a content in my android app by facebook 4.0.0 sdk. I exactly followed <a href="https://developers.facebook.com/docs/sharing/android#share_dialog" rel="noreferrer">facebook share document</a> but got no result. Share dialog open when I press share button but no content is in it. If I click ok it share an empty string just. Please show me a way to fix this.</p>
  
  <p><strong>Edit</strong></p>
  
  <p>BTW When I remove Facebook native app from my phone, I can share with webview of facebook.</p>
