Huaren 2.0

Updated: 2.0.2 was released. It should be working on android 2.1 and 2.2.
I don't know if somebody has noticed, I'v taken the huaren app off from the android market right after I published 2.0. It seems like 2.0 will break since it contains some code only works in gingerbread (2.3). I will republish it soon.
