Aosp Building Error: Symbol Not Defined

I'm trying to build the cornerstone based on AOSP 4.3_r2.2. I got a lot of errors during the building like these: frameworks/base/core/res/res/values/public.xml:244: error: Symbol

Solution 1:

Finally resolved the problem, by did these: 1. Removed the symbol definition from public.xml; 2. Replaced android.view.Surface with android.view.SurfaceControl, and WindowManagerService.DEFAULT_DIM_DURATION with WindowAnimator.DEFAULT_DIM_DURATION.

After that, I compile it succeed, and it can be run, although there still have some problems.
