Question

I put the Android key hash in the developer settings, like described here:

http://developers.facebook.com/docs/mobile/android/build/#sig

it works, using the app for months already.

Now I want to enable single sign-on.

Did the steps, described in the same page (in the Android app and enable single sign on in the developer account). But I get in the app:

invalid_key:Android key mismatch. Your key ”
xxxxxxxxxxxxxxxxxxxxxxxx

” does not match the allowed keys specified in your application settings. Check your application settings at http://www.facebook.com/developers

(I removed the key for SO).

What is the problem? Everything works if I don’t use single sign on. Is the key maybe not used, when not using single sign on (don’t believe that).

Thanks.

Answer 1

Ok, it seems that the key hash is necessary only for single sign-on. So mine is probably wrong, and it’s ignored when not using single sign-on.

Edit: Confirmed, changing the key fixed the problem.
