SDK sends wrong key so login fails with invalid key if facebook app is installed

I created keys from my debug keystore as well as my keystore and set them as in the "Main Android App" field for the facebook app.

I've tested this on multiple devices and it always works with debug.keystore (when deploying from eclipse). But when I sign the app package with my keystore, it only works if the facebook app is not installed on the device.

If the facebook app is installed, it sends a different key which I don't know.

I generated the hash key very carefully by assigning the correct path and password as explained in the instructions from Facebook.

Note. When working with debug.keystore, it works, but it seems to be using the auth dialog and not the facebook app.

thank
