Maybe not directly, but without iOS it wouldn't exist. Google have never been very good at coming up with new ideas, just copying others, usually badly. My opinion of why Android is so popular is because telephone companies push it. Cheaper phones, less subsidy. People get iPhones cause they want one. Then spend money at the app store and use it frequently for things other than phone calls. Most people get Android cause it was the cheapest plan and use it as a phone.
