AndroidFacebook4.0 logout programmatically-AndroidFacebook4.0LogoutProgrammatically

In my app, I allow users to login to and logout from Facebook programmatically.

In my application, I allow users to log in and log out from Facebook programmatically.

For login, I call:

When logging in, I call:

ArrayList permissiOns= new ArrayList();
 permissions.add("manage_pages");
 permissions.add("publish_actions");
 LoginManager.getInstance().logInWithPublishPermissions(App.activity, permissions);
 

And for logout, I call:

For cancellation, I call:

FacebookSdk.sdkInitialize(getApplicationContext());
 LoginManager.getInstance().logOut();
 

When I call the logInWithPublishPermissions() method above, the official Facebook app opens prompting the user to login, and after the user logs in, they become logged in to both my app as well as the official Facebook app.

When I call the logInWithPublishPermissions() method above, the official Facebook app opens, prompting the user to log in, and after the user logs in, they log into my app program as well as the official Facebook app.

However, when I call the logout() method above, the user is not logged out from the official Facebook app. Is there a way to make this happen, i.e. signing out from my app will force signing out from the official app ? A type of ‘single sign-off,’ if you will?

No. It is a common problem even with oauth type “signup via facebook or gmail”, where even if you logout from the third party app, you dont get out of fb or google. There is no mechanism which can make your app issue logout command to facebook app.

No. This is a common problem, even with the oauth type “Register via facebook or gmail”, you won’t log out of FB or Google even if you log out from the 3rd party app. There is no mechanism for your application to issue logout commands to the facebook application.
