Ok so I just submitted Traktor Digger to two app stores in China...
1) Samsung app store http://seller.samsungapps.com
2) Lenovo app store http://developer.lenovomm.com/developer/
Those are the top two smartphone companies in China. And they each have their own app store preinstalled on their phones. There are tons of different app stores in China, but I figured this was the best approach. Further note that AdMob works in China. http://www.bloomberg.com/news/2012-08-22/google-finally-leads-in-china-in-app-ad-sales.html
When you're on those Chinese websites, if you are using Chrome browser, you can right click on the site and choose Translate.
I haven't noticed any significant improvement in my Admob revenue based on this move to China.
What I have noticed, at least in the Lenovo app store, are hacked copies of my game that existed before I even posted it there myself. In fact when I tried to upload my game I got an error like "package name already exists". I emailed support firstname.lastname@example.org
who were suprisingly responsive (responded within 24hrs). They then told me they "fixed" the problem... which I read to mean they removed one of the hacked copies so that I could upload mine lol. Today I sent them another email asking them to remove the remaining hacked copies from their store. We'll see what happens.
If you use Google Translate http://translate.google.com
and find the Chinese translation of the name of your game, you can then search the Lenovo app store in Chinese and see if there are any illegal copies of your game there http://www.lenovomm.com/appstore/html/index.html
Try searching for Traktor Digger there as an example. Note the v2.99 copy is my legal copy, the other copies are hacked copies. Use these Chinese characters in your search...拖拉机
I've heard that the hackers reprogram/repackage your game so that THEY are the ones who receive any Admob revenue from it. So at this point I'm guessing everybody in China has already played the hacked copies of my game, so it was kind of pointless to upload my legal copy of it at this point. That's why I suggest to all of you to upload copies of your games ASAP so that Chinese users play your copy of the game first, and you are the one who gets the money.
Nevertheless there are tons of other Chinese app stores to consider as well...http://www.gizchina.com/2012/08/14/20-ways-to-get-free-android-apps-downloads/
