title: Cannot generate correct facebook key hash for release apk?
body: <p>Steps that I've tried, 
  1) Generated the keyhash (although i got a warning/error as "keytool: command not found") from the official developer documentation.(<code>keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64</code>)</p>

  <p>2)Also tried the the keyhash shown in the error message while signing in.</p>
  
  <p>Still, none of the above keyhashes worked, interesting i was successfully able to signin to facebook in my debug version.
  Please Help</p>
