Use of Basic4Android over an existing Java/Eclipse setup

:sign0104:I am currently working with the standard Android/Java/Eclipse installation and have got to a point where I don't think I can continue. I believe Basic4Android may solve my issue. I am using Java 6 for it, so installing Java 7 shouldn't prove a problem, but do I have to re-install Android?

I want to be able to return to the Eclipse setup, just in case, and I am hoping the Basic4Android installation won't interfere with it.

Thanks
