android facebook hash key

RELEASE_KEY_ALIAS and RELEASE_KEY_PATH values for generating key hash

1- I’m trying to generate my key hash for integrating Android with Facebook. I understand that I have to run the following command on prompt (I am on Windows):

keytool -exportcert -alias <RELEASE_KEY_ALIAS> -keystore <RELEASE_KEY_PATH> | openssl sha1 -binary | openssl base64

But where can I get the values of RELEASE_KEY_ALIAS and RELEASE_KEY_PATH?
Please help me, I have browsed a lot and haven’t find where to get them.

2- A stackoverflow answer said that another way to obtain the hash key was to download this, and run in on my android device. Buy when I import it into Eclipse I get a bunch of errors which I don’t know hot to fix. The question was this one
