Let's be honest, there's no place for you in the android developing world if you haven't mastered the idea and logistics of Java. Don't go hald-assed in to it, you'll just end up with long nights and tears.

All the basics. Do not go into Android till u have solid understanding of the basics like inheritance, typecasting, interfaces, etc
