title: How to find Android application signature in Facebook API using debug logs
body: <p>I have been following the Facebook API guide on <a href="https://developers.facebook.com/docs/mobile/android/build/#sig" rel="nofollow noreferrer">https://developers.facebook.com/docs/mobile/android/build/#sig</a> and in step 5 it says </p>
  
  <p>There are two ways to find your Android application signature:</p>
  
  <p>1) From debug logs generated during Single Sign On when there is a signature mismatch.</p>
  
  <p>2) From the Java JDK keytool.</p>
  
  <p>How do I find it using debug logs? I have enabled the logs as they said, using <code>private static boolean ENABLE_LOG = true;</code>. I want to know this because I have tried to get it following step 2, but <a href="https://stackoverflow.com/questions/12620601/facebook-sso-doesnt-work-on-android-device">unsuccessfully</a>. I can't find anything in the logs that would tell me the correct Key Hash.</p>
