  /**
   * 
   * Main class of the SocialAuth Android SDK. Wraps a user interface component
   * with the SocialAuth functionality of updating status, getting user profiles,
   * contacts, upload images, get user feeds, get user albums on Facebook,
   * Twitter, LinkedIn, MySpace, Yahoo, Google FourSquare, Runkeeper, SalesForce
   * and Yammer. <br>
   * 
   * Currently it can be used in four different ways. First, it can be attached
   * with a Button that user may click. Clicking will open a menu with various
   * social networks listed that the user can click on. Clicking on any network
   * opens a dialog for authentication with that social network. Once the user is
   * authenticated, you can use various methods from the AuthProvider interface to
   * update status, get profile, contacts, user feeds, album feeds and upload
   * images. <br>
   * 
   * Secondly, it can be attached to a LinearLayout for creating a Bar with
   * several buttons, one for each social network. Clicking on these icons will
   * open a dialog which will authenticate the user and one the user is
   * authenticated, you can use various methods from the AuthProvider interface to
   * update status, get profile, contacts, user feeds, album feeds and upload
   * images. <br>
   * 
   * Thirdly, it can be used as shareactionprovider in actionbar.. Clicking on it it will show list 
   * of all providers along with other apps which are use by ACTION_SEND intent. The socialauth
   * providers will be shown is added else it will default application. For example
   * if you added socialauth facebook provider then it will show  socialauth facebook
   * provider else it will show default facebook application.<br>
   * 
   * Lastly, you can just launch the authentication dialog directly from any event
   * you prefer. Examples for all of these ways is provided in the examples
   * directory of the SocialAuth Android SDK
