    copied!<p>I have created a Android application with the Facebook Android SDK 3.0.</p> <p>I created a working application (when running from Eclipse). It will create a Facebook session (with com.facebook.UiLifecycleHelper) and a login button (with com.facebook.LoginButton) so that the user can login into Facebook. The Facebook authentication dialog is showing and after filling in the credentials the login button will show that the user is logged in into Facebook. </p> <p>So, far everything works fine, but when I'm making a release build (with Proguard enabled) I get the following exception:</p> <pre><code>E/AndroidRuntime(14690): FATAL EXCEPTION: main E/AndroidRuntime(14690): com.facebook.FacebookException: Unable to save session.
