Android Facebook login problem

Hi!
I’m having problems while connecting to facebook. The window which appears after I execute facebook.login() command only shows for about 3 seconds and then it disappears. I tried logging with SSO(with key generated from debug.keystore which is in Corona SDK files, correct package name and class name “com.ansca.corona.CoronaActivity”) but there wasn’t any login window at all.
I also used libFacebook wrapper library and in the simulator it worked well but on my Xperia not.
I though that it could be key hash fault(I have non-premium Corona SDK and I can’t generate private keys) but as I read about it SSO isn’t vital for app to login.
