Publishing On Facebook With Sdk 3.0 And Android Doesn't Work

I set a connection to fb in my app: clicking a button the app does the login, posts on the wall and then does logout. Everything works perfect for me with my developer account, but

Solution 1:

I think that your app may be placed in the sandbox mode and which is what causing others not from accessing your app. You may be the admin of the app and with your account you can access the app even in sandbox mode

So disable it to make your app work for others. Also check whether you have added the keyhash generated using your keystore file

Solution 2:

Turn-off the sandbox mode in your App settings.
