title: How to perform facebook Login without permissions?
body: <p>i am using the java/android facebook login sdk 5.5.1. The  <code>LoginManager.getInstance().login(activity, permissions)</code> (<a href="https://developers.facebook.com/docs/reference/androidsdk/current/facebook/com/facebook/login/loginmanager.html/" rel="nofollow noreferrer">https://developers.facebook.com/docs/reference/androidsdk/current/facebook/com/facebook/login/loginmanager.html/</a>)  returns a cancelled login state when i try to pass an empty array of permissions to that method.</p>
  <p>I truly don't need an email or any other details from the facebook user's profile. I only need the accesstoken + userid.</p>
  <p>How can i realise that behaviour?</p>
  <p>Thanks in advance</p>
