See https://developers.facebook.com/docs/android/share-dialog/#handling-responses

You can tell if the user has cancelled by calling

String gesture = FacebookDialog.getNativeDialogCompletionGesture(data);
if (gesture != null) {
  if ("post".equals(gesture)) {
    // the user hit Post
  } else if ("cancel".equals(gesture)) {
    // the user hit cancel
  } else {
    // unknown value
  }
} else {
  // either an error occurred, or your app has never been authorized
}

where data is the result bundle. However, it will only return a non-null value IF the user has logged in via your app (i.e. you have at least basic_info permissions). If the user has never logged in or authorized your app, then the only thing you'll see is the DID_COMPLETE, and it will always be true unless an error occurred. This is by design.
