title: Facebook key hash does not match any stored key hashes
body: <p>I'm really having troubles with the Facebook hash key.
  I generated it in my Eclipse.. proof:

  <p>Then I went to <a href="https://developers.facebook.com/" rel="noreferrer">https://developers.facebook.com/</a> and registered a new app.

  <p>And finally I've set my hashkey at the settings of Facebook developers:

  <p>But no whatter I do I keep getting the same error log:
  "Key hash B5dWUEYfZJL/...........jyA= does not match any stored key hashes"</p>
  
  <p>Does anybody know what I did wrong or how I can fix this problem?
  If I used the id and name from the HelloFacebookSample inside my own app everything works.
  So it HAS to do with the key hash, id or name I've set somewhere most likely..</p>
  
  <p>Thank you,
  Yenthe</p>
