Having lived in China for the last 5-6 years or so, I thought I'd share my 2 cents.
Basically guys, forget about China or forget about making money from China. Focus on countries that have ethics and a real antipiracy laws. From my experience Japan, South Korea, Thailand and Philippines are the way to go. You can actually sell paid apps in the former 2 countries and make money of ads int the latter 2.
As for China, most of the phones being sold here come with preinstalled black market apps, that have everything from free premium versions to hacked add supported versions of most apps. Google Play is not available and personally I don't know a single person who uses lenovo or samsung app stores.
Here's the most popular black market site at the moment: http://apk.91.com/
It's got an android app for it an everything and I'm pretty sure it's got some of my apps in there as well (that I didn't publish).
So yeah, I guess the point I'm trying to make is, don't waste too much time worrying the Chinese market, and try to break through in neighboring countries. Sure China's population is huge, but most of it is too poor or unwilling to spend 99 cents on an app, when they can get it for free. And the 1% of the population that have the means to buy whatever they want, are using iPhones
