title: new to android - only able to login to facebook when hash key is in the person's developer's account
body: <p>Facebook SDK comes with a login and post app called: HelloFacebookSample. When I login it works fine, but if anyone else logs in there, it wont work. The reason is because it only accepts those facebook accounts who are developers and have the applications key hash assigned in their facebook developer's dashboard.</p>
  
  <p>Example, if I make my john doe facebook uers a facebook developer and assign the key hash in his dashboard, go back to my phone and launch my app and try to login as John doe.. it works fine. But i should have to ask my users to have to do that... is there any way around this? I tried to look through the documentation but could not find anything.</p>
