I am new to this please help

I am running windows 7 64 bit

UPDATE: Tried and Uninstall and install version 6 instead of 7 but did not solved my problem.

I donot know why

You are using java 7..

I am sure android sdk does not fully support java 7 as oracle just released java 7.

Go for lower versions of java like java 6 or jdk 1.6
