Chinese officials report that Android's popularity has caused the country to become "too dependent" on the operating system. Although other companies have tried to build on top of Android, the ministry complained that the operating system's "core technology and technology road map is strictly controlled by Google."
Just last month, China surpassed the U.S. as the world's largest smartphone market, and Android is running on over two-thirds of all smartphones in China. Gartner data show Android leaping from .05 percent market share in 2008 to controlling 72.4 percent of the Chinese smartphone market.
