Answer 1

Go to someone's facebook profile. Right click on the profile picture and copy the link address. Paste it on a text editor and you will see the "referrer_profile_id" parameter at the end of the URL. It is the facebook ID of that user.

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://messaging/" + FbUserID));
startActivity(i);
