/** 
 * Full authorize method. Starts either an Activity or a dialog which prompts the user to log in to Facebook and grant the requested permissions to the given application. This method will, when possible, use Facebook's single sign-on for Android to obtain an access token. This involves proxying a call through the Facebook for Android stand-alone application, which will handle the authentication flow, and return an OAuth access token for making API calls. Because this process will not be available for all users, if single sign-on is not possible, this method will automatically fall back to the OAuth 2.0 User-Agent flow. In this flow, the user credentials are handled by Facebook in an embedded WebView, not by the client application. As such, the dialog makes a network request and renders HTML content rather than a native UI. The access token is retrieved from a redirect to a special URL that the WebView handles. Note that User credentials could be handled natively using the OAuth 2.0 Username and Password Flow, but this is not supported by this SDK. See http://developers.facebook.com/docs/authentication/ and http://wiki.oauth.net/OAuth-2 for more details. Note that this method is asynchronous and the callback will be invoked in the original calling thread (not in a background thread). Also note that requests may be made to the API without calling authorize first, in which case only public information is returned. IMPORTANT: Note that single sign-on authentication will not function correctly if you do not include a call to the authorizeCallback() method in your onActivityResult() function! Please see below for more information. single sign-on may be disabled by passing FORCE_DIALOG_AUTH as the activityCode parameter in your call to authorize().
 * @param activity The Android activity in which we want to display the authorization dialog.
 * @param applicationId The Facebook application identifier e.g. "350685531728"
 * @param permissions A list of permissions required for this application: e.g. "read_stream", "publish_stream", "offline_access", etc. see http://developers.facebook.com/docs/authentication/permissions This parameter should not be null -- if you do not require any permissions, then pass in an empty String array.
 * @param activityCode Single sign-on requires an activity result to be called back to the client application -- if you are waiting on other activities to return data, pass a custom activity code here to avoid collisions. If you would like to force the use of legacy dialog-based authorization, pass FORCE_DIALOG_AUTH for this parameter. Otherwise just omit this parameter and Facebook will use a suitable default. See http://developer.android.com/reference/android/ app/Activity.html for more information.
