Becoming an Android Mobile developer

Hi guys. I would like to get into the Android Mobile development field but have very minimal programming experience. Can someone advise me on how to get started. To what level do I need to know java programming before starting a Android mobile developer course? Do I need to be a complete java programmer first as java is quite big. Please advise. Thanks alot.
