title: Rails 3.2 and phonegap
body: <p>I have a rails application currently running ,I want to make a mobile application for it ,I don't want to learn objective-c or java ,I read many articles about phonegap and how I can use it to make a cross platform web apps
  Phonegap compile css/htm/js 
  Rails application has its ruby code and also html.erb and js.erb extensions
  So how can I make a mobile application ,mainly for android for ex as a back-end of my rails excising server<br>
  I will use jquery mobile as a UI for the application 
  Do I need to make an api and use emberjs or angularjs or backbone to contact with the server ?
  Tutorials in using rails as a back-end for a mobile application are so rare </p>
