Assuming you are familiar with using the AccountManager on Android (see http://alandjackson.wordpress.com/2011/01/05/android-tutorial-snippetsauthenticating-accounts/ for a tutorial) you will need to use the Android
AccountManagers getAuthToken method with an authentication token type string set tolocal.
