How set JAVA path to Environment Variables on Windows (7)
Select Start menu > Computer > System Properties > Advanced System Settings(properties).
Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example

First cteate big icon 512x512 px formtat .PGN in graphics editor as Photoshop, Gimp, Piant.NET and save image.
If you create new project via Eclipse and choice your 512x512 image for ic_launcher.
Eclipse will make all icons from this image for new application very well.
