android - Facebook API login fails with FB app installed on phone

Question

I am building an app, which is going to have support for facebook. I have downloaded facebook API and their sample called "Hackbook" from original Git repos. The problem is with login - if original FB app is not installed on phone, the login is going through custom dialog and everything works, but if FB app is installed, the Hackbook automatically redirect to original FB app, and then nothing happened. It's impossible to login. I have tested this on five different phones, and always was the same problem.

I had a similar problem. In my case, I had not created a hash key using my signing key. I just had the one hash key created using the debug.keystore default signing key.

As soon as i created a hash key using my app release signing key, that problem was sorted out. If you haven't already done this, create a new hash key using your signing key (for uploading on the market) and add that to your app's facebook control panel.

Hope this helps.
