title: Android Facebook SDK 4 ShareLinkContent fails
body: <p>I use the code below to allow app users to share my app via Facebook. </p>
  
  <pre><code>ShareDialog shareDialog = new ShareDialog(this);
  
  ShareLinkContent content = new ShareLinkContent.Builder()
                                  .setContentUrl(Uri.parse(myUrlStr))             
                                  .setImageUrl(Uri.parse("myImageUrlStr))
                                  .setContentTitle(myContentTitleStr)                              
                                  .setContentDescription(descriptionStr)
                                  .build();
  
  if (ShareDialog.canShow(ShareLinkContent.class) == true)
      shareDialog.show(content);
  </code></pre>
  
  <p>This code will invoke the Facebook Messenger, and let users select how to share my app. The code was perfectly working, but now for some reason it stopped! Now if try to share my app, I get the following message and the post fails:</p>

  <p>I've seen <a href="https://stackoverflow.com/questions/27176382/android-facebook-sdk-action-setplace-error-in-custom-stories-in-andoridfeed-d">this</a> and <a href="https://stackoverflow.com/questions/29602381/sharing-to-facebook-shows-error-we-are-sorry-this-post-is-no-longer-available">this</a> posts, but they do not apply to my case, since, as mentioned, posting was perfectly working and without any reason it stopped one day. </p>
  
  <p>Do you know if something has changed on the required permissions from Facebook? This is really weird...</p>
