Answer 1

Just remove this line params.putString("to", "1782990807"); and choose friends.You can choose multiple friends.

The Facebook SDK for Android provides a method to let you publish stories from your app to a user's timeline. You can also use this method to post a status update on your user's behalf. This method uses the Graph API, and is an alternative to using the Feed Dialog
