Logout Facebook Android SDK

Question

I use the LoginButton from the Facebook Android SDK to login to my application. How do I programmatically log out the user from any Activity?

Starting Facebook SDK 4.0 you need to call

LoginManager.getInstance().logOut();

I am not seeing that this forces the user to re-authenticate. :( – swooby May 22 '15 at 02:37

If you are using facebook SDK 4, you first need to initialize sdk:

FacebookSdk.sdkInitialize(getApplicationContext());

And then just do:

LoginManager.getInstance().logOut();

See here for more details.
