title: Tag a photo in facebook post on android sdk
body: <p>I have a problem sharing a photo using facebook's APIs on Android sdk.
  In the way I share the photo is correctly uploaded, but I can't manage how to tag people.
  I tried with my own userID, but in the following way the tag doesn't appear.
  I read many thread on this and other forums, but I didn't find any working answer.</p>
  
  <p>I hope you could help me,
  this is my code (where 515159228582518 is my userId) :</p>
  
  <pre><code>Bundle postParams = new Bundle();
  
  Bitmap bmp = Data.getData().getFinallyCard();
  ByteArrayOutputStream stream = new ByteArrayOutputStream();
  bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
  final byte[] data = stream.toByteArray();
  
  postParams.putString("message", "Message");
  postParams.putByteArray("picture", data);
  
  postParams.putString("place", "166793820034304");
  postParams.putStringArray("tags", new String[]{"515159228582518"});
  </code></pre>
