logout not working

[mmrk09]

When I logout a user on facebook they are automatically logged in every time in facebook afterwards, never prompted again.

adapter.getCurrentProvider().logout(); <--doesn't work

Yes, none of the below work:

• adapter.getCurrentProvider().logout();
• boolean signOutResult = adapter.signOut(thisContext, SocialAuthAdapter.Provider.LINKEDIN.name());

What I did to work was to erase shared preferences for the file "getPackageName() + "_preferences".xml.

adapter.getCurrentProvider().logout();
adapter.signOut(thisContext, SocialAuthAdapter.Provider.LINKEDIN.name());
StorageUtils.clearAllSharedPrefs(StorageUtils.getAllSharedPrefsFromFile(getPackageName() + "_preferences", thisContext));

public static void clearAllSharedPrefs(SharedPreferences sharedPreferences) {
sharedPreferences.edit().clear().commit();
// in this case we want to do it fast, on the UI thread, this why we do not use .apply, but .commit
}

public static SharedPreferences getAllSharedPrefsFromFile(String fileName, Context context) {
return context.getSharedPreferences(fileName, MODE_PRIVATE);
}
