title: Android Facebook SDK 4.0 ShareDialog doesn't show long texts
body: <p>I am a newbie developer on Android and Facebook SDK. I want to share my long description text content to facebook via Facebook SDK 4.0 on Android.</p>
  
  <p>I have a ShareActionProvider on my App and it's working fine with my ShareDialog method. But I have a long description in my app and I want to share this description on Facebook. I imported and configured Facebook Android SDK and It's working fine with this method;</p>
  
  <pre><code>if (ShareDialog.canShow(ShareLinkContent.class)) {
  
                         Spanned faceKonu= Html.fromHtml(mShareKonu);
  
                          ShareLinkContent linkContent = new ShareLinkContent.Builder()
                                  .setContentTitle(konu)
                                  .setContentDescription(faceKonu.toString())
                                  .setContentUrl(Uri.parse(getString(R.string.share_onfacebook_url)))
                                  .setImageUrl(Uri.parse(getString(R.string.share_onfacebook_image_url)))
                                  .build();
  
                          shareDialog.show(linkContent);
                      }
  </code></pre>
  
  <p>But this method shows my description text too short on wall or somewhere in facebook. </p>
  
  <p>This is my description screen : <a href="http://i.imgur.com/56c2vIw.png" rel="nofollow">http://i.imgur.com/56c2vIw.png</a>
  This is the facebook api when I tap the share on facebook on ShareActionProvider menu : <a href="http://i.imgur.com/LpvH9FT.png" rel="nofollow">http://i.imgur.com/LpvH9FT.png</a></p>
