title: Facebook hash key not working
body: <p>So using the keytool command I was able to generate a hash key for my Android app which uses Facebook login. For purposes of this question, the hash the keytool outputted was "abcdefg=". But when I try to sign on to Facebook from my app, the error says "Key hash abcdefg does not match any stored key hashes" and shows the same exact key I got from keytool just without the equal sign at the end. Why is it not working? Also, when I try to manually type in the key hash on my Facebook developer console (instead of copy/paste), it won't take the key without the equals sign because it only takes keys whose character count is divisible by 4 (my key with equals sign has 28 chars, the key without has only 27 chars). Can someone help?</p>
