User user = controller.fetchMe();

return user;
}

@Override
protected void done()
{
User user;
try
{
BackgroundProcess.this.mainGui.appendProgressLog("Fetched user record");

// get the user object from doInBackground()
user = get();
mainGui.setCurrentUser(user);
}
catch (InterruptedException | ExecutionException e)
{
BackgroundProcess.this.mainGui.appendProgressLog("ERROR fetching facebook data "+e.getMessage());
e.printStackTrace();
}

}
};

BackgroundProcess.this.mainGui.appendProgressLog("Fetch Current User - Connecting to Facebook");
