How do i export the key for my app android to use with facebook sdk

How do i export the key for my app using the debug defaults specified by the Android SDK and Eclipse I am trying to generate a key for use with the Facebook SDK I have tried

keytool -exportcert -alias androiddebugkey -keystore ~/.an开发者_Python百科droid/debug.keystore | openssl sha1 -binary | openssl base64

if it helps i am running ubuntu 11.04 but what it generates is gibberish if i may say so thanks alot

If gibberish means random characters and numbers, about 30 of them: Thats fine and what you need. Just take them and copy them to your applications profile on Facebook.

If not, please post the error or command output you get while doing so.
