But SDK4 seems not to support Session anymore, and in official docs, they mention:
There are two ways to implement Facebook login on Android:
LoginButton class - Which provides a button you can add to your UI. It follows the current access token and can log people in and out.

You can use LoginManager.getInstance().logOut();, even if you use LoginButton because

This UI element wraps functionality available in the LoginManager.
EDIT: Just to mention that this works for Facebook SDK v4. I don't know if they will change it in the future.
@as batoutofhell mention, don't forget to put FacebookSdk.sdkInitialize(getApplicationContext()); to initialize the facebook sdk. Please see here for the details.
