Generate class diagram Eclipse with Android SDK

I have a Android project f开发者_开发技巧or which I want a class diagram. What is the best way to do this? I have installed the MoDisco, GEF, UML2 Extender. Are these sufficient? What is the simplest way to generate a UML from the classes with activities I already have?
