我正在尝试基于AOSP 4.3_r2.2构建基石。我在建造过程中犯了很多错误，比如：

我在这里搜索了一下，发现了这个问题。所以我知道这可能是缺少符号定义问题。但当我查看public.xml时，我发现它们属于不同的类型，比如：
<java-symbol type="bool" name="config_bluetooth_sco_off_call" />
<java-symbol type="bool" name="config_enableDreams" />
<java-symbol type="drawable" name="ic_suggestions_add" />
<java-symbol type="drawable" name="ic_suggestions_delete" />
<java-symbol type="id" name="backspace" />
<java-symbol type="id" name="carrier" />
<java-symbol type="id" name="dangerous_perms_list" />
...
我还发现frameworks/base/core/res/MakeJavaSymbols.sed中有一个脚本文件，上面写着命令
make framework 2>&1 | sed -n -f MakeJavaSymbols.sed | sort -u
可以用于生成丢失的资源。我搜索了很多，我找到的只是为了运行这个命令，它会输出缺失的部分。但我跑了，什么也没发生。所以我的问题是，我应该在哪里以及如何添加这些缺失的符号？它们有数百个，我需要手动添加吗？我错过什么了吗？由于我是AOSP框架的新手，所以请帮忙。
通过以下操作最终解决了问题：1.从public.xml中删除了符号定义；2.将android.view.Surface替换为android.vview.SurfaceControl，将WindowManagerService.DEFAULT_DIM_DURATION替换为WindowAnimationr.DEFAULT_DIM _DURATION.
之后，我成功地编译了它，并且它可以运行，尽管仍然存在一些问题。
