Instead of implementing everything yourself, try using the free and open source SOOMLA Profile plugin for all of your social network needs: https://github.com/soomla/unity3d-profile

Also available on the asset store for download: https://www.assetstore.unity3d.com/en/#!/content/24601

It covers Facebook, Twitter and Google+ and has a unified API for logging in, posting statues, uploading images and getting friends lists. For proper disclosure, I'm one of the founders.

Version 4.3.6 of the sdk should fix this problem. It's available here: https://developers.facebook.com/ We are still waiting for it to be approved on the asset store, so the only place to get it right now is from Facebook's site.

Note - it's still broken (5/2014) IF you use a Mac. Just follow the "Rafael solution", discover your hash properly from public void OnLoginComplete(string message). Cheers

Answer 3

So after being frustrated for a few days with having to trace out the key to my phone, I decided to look into what it was doing.

After some research it turned out that when you published to an android device, facebook would use the keystore that was defined in your publish settings, not your .android/debug.keystore file. So I went in and changed the sdk to make it work the proper way. Essentially I changed the SDK to look at the ProjectSettings instead of the debug directory for grabbing the key hash. In the FacebookAndroidUtils.cs I added the following.

// Using the user defined keystore values instead of the debug one.
degbugKeyHash = GetKeyHash( PlayerSettings.Android.keyaliasName, PlayerSettings.Android.keystoreName, PlayerSettings.Android.keyaliasPass, PlayerSettings.Android.keystorePass );

I created a small repo that provides the fix as well as some gui changes to make it more easy to update the key hash.

Update - Fixed a bug with OS X related to escaping spaces on the string path

Hope this helps!

Take the "email" permission out of the login function and try it. Oops I thought I seen the "publish_actions" permission in there too.

Make sure the loginactivity in the manifest is in portrait.
