As the title of this question suggests, I am looking forward to develop app(s) on Android platform without using Java at all. It doesn't mean I have some kind of vendetta against this beautiful language or I don't know how to develop apps in Java. But I am considering that my application(s) can be developed by only using XML, JavaScript and Ajax. So do I still have to rely on Java?  Will there be any disadvantage(s) of not using Java?Will I still be able to extend my app(s) in the future?Am I asking a really stupid question here?Kindly help me out.Edit:The app I am working on (still on whiteboard, need expert opinion on this approach) will simply fetch news from different news sources and will display to its user.
