Okey, I\'ve done all the business, followed all the steps, but still can\'t get it to work. The simple Example app that comes with the Facebook SDK, is working on the emulator a

I had a similar problem. For me, it was resolved when I uninstalled the latest update of the Facebook app and now only have the native Facebook app v1.2. (Means, when I go into the market and search for Facebook, the "Facebook for Android" would be displayed as 'not installed' on my device).

On my Nexus One (Android 2.2.1), when I had the latest Facebook app installed, there was not 'uninstall app' buton, only a 'Uninstall latest updates', which is what I did. In fact, I can't even uninstall the entire Facebook (now v1.2) app for whatever reason, the uninstall button is disabled/greyed out. But in this status, the samples seem to work.

At least, I could get the simple and stream app to work this way.

Edit / Solution:

Ok, I got it working now. I found that I copy/pasted the wrong key hash, due to some weird behaviour of keytool under windows and a wrong command syntax in the ReadMe file of the Facebook SDK.

The parameter to be used should be "keytool -export ..." and not "keytool -exportcert ..."; if you do use the second/wrong parameter, keytool would still print out a hash key (withouth asking for any key password though), but the hash is wrong.

Now I got SSO working as well.

This is my call on windows:

keytool -export -alias androiddebugkey -keystore "C:\Documents and Settings\myuser\.android\debug.keystore" | openssl sha1 -binary | openssl enc -a -e
