I have created a simple android app and signed it using the Eclipse export method.

Then I use the export cert command of keytool.

keytool -exportcert -alias my_alias -keystore "G:\mypath\app\android.keystore"|"C:\ssl\bin\openssl" sha1 -binary |"C:\ssl\bin\openssl" base64

I got some “hash code”. I added this hash code to the facebook panel for native android app and checked the login with facebook.
While logging in, facebook gives and error stating that the hash code of the app is not allowed. i.e. is not given on the list of allowed has codes.

What am I doing wrong ? Is the question clear ? Please comment I will make the necessary changes.

    Ideally you add the key hash to two places:

    • your overall developer settings (so that you can run the Facebook samples)

    • the settings for each of your apps themselves

    These are described in steps 4 & 5 of the Getting Started guide, respectively: https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/

    Make sure you have done both.
