It looks like Google is listening to the community about pushing a standardized design practice for the look and feel of the Android OS. They just launched a new website dedicated to solidifying aesthetic design standards for Android. It's called, simply enough, Android Design, and doesn't force anyone to adhere to a specific look, *cough* Apple *cough*, but it does create a recommended guidelines that will help budding developers differentiate their apps on the Android OS from looking like rehashed iOS apps. It's basically just a site full of utilities, hints and suggestions to help developers follow a pattern that helps Android OS look more like they fit in with the new Ice Cream Sandwich design elements.
It's nice to see Google working toward a cohesive vision that is still open to creativity. Check out the site and share your thoughts in the thread.
