Facebook + Android Key Hashes

I'm trying to get work Facebook login in my Android app and i stack on key hashes: I made them using

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

then I upladed it to facebook. Now if I press login button, Facebook showing for 1 sec and shuting down, Nothing is showing in Logcat what is problem?
