title: facebook hash key when using android studio
body: <p>i am using android studio to develop an app which uses facebook sdk.</p>
  
  <p>when i used the following command</p>
  
  <pre><code>C:\Program Files\Java\jdk1.7.0_21\bin&gt;keytool -exportcert -alias androiddebugkey
   -keystore "C:\Users\ninad\.android\debug.keystore" | "D:\OpenSSL\bin\openssl" s
  ha1 -binary |"D:\OpenSSL\bin\openssl" base64
  </code></pre>
  
  <p>it returned <strong>y5EquINHD6DvwVJFyJTuUEY3NSU=</strong></p>
  
  <p>when using this hash key facebook shows the error </p>
  
  <p>invalid android_key parameter. the key <strong>c33Tm0FL_-kxyaPZq1JBLDh767U</strong> does not match any 
  allowed key.</p>
  
  <p>Is the hash key needed for facebook different when using eclipse and android studio? which among these is my correct hash key?</p>
  
  <p>I added both the hash Key to my app in facebook. still the app shows invalid android_key parameter. </p>
