I am trying to implement Facebook into my Android app.

Everytime though, the facebook stuff fails because of an “Invalid key” error although I’ve been through the steps of setting up an app on FB and getting the key via keytool and so on.

Is there any ideas I can try to fix it ?
Is it normal for a hash code to have symbols such as ‘/’ or ‘=’ in it?

    You must have installed your .apk signed in your device, be sure to use the same keystore to sign your app and to get the Key hash, and yes, your key Hash will contain ‘/’ or ‘=’ i.
